During the observation period, there was no clinical implant failure and the suvival rate for implantation and maxillary sinus floor augmentation was 100 %. Histological examination in a previous report on maxillary sinus augmentation using β-TCP (Cerasorb®), Szabo et al. compared bilateral maxillary sinus augmentation in the same patients using β-TCP and iliac bone at 6 months after surgery ...
As grafting materials for maxillary sinus floor augmentation, autogenous bone, which is considered as the gold standard and reported first by Boyne et al. using iliac bone graft, has been used as the first-choice material. In terms of osteogenic, osteoinductive, and osteoconductive properties, autogenous bone is considered ideal; however, the use of autogenous bone places great physical stress on ...
Change in height of bone surrounding the implant (height from the maxillary sinus floor to the implant tip): Immediately after surgery, all patients had grafted bone between the implant tip and the maxillary sinus floor, with a mean of 2.00 ± 1.51 mm.

The mean age of the 30 patients was 57.4 (40–75) years, and the male/female ratio was 4:26. The mean postoperative observation period was 3 years and 8 months (the maximum period was 5 years and 0 months; the minimum period was 2 years and 2 months). Total of 58 implants were placed at premolar and molar region. There were no dropouts, such as participants not visiting the clinic, during t...

Radiographic examinations to determine changes in bone mass in maxillary sinus floor augmentation have been conducted primarily using panoramic radiography [8–12], which allows for the assessment of the height of the maxillary sinus in only two dimensions. In addition, it does not allow for detailed examination or measurement of the interior of the maxillary sinus without factoring in magnificat...
The maxillary sinus gradually expands after birth and becomes fully pneumatized with the eruption of all permanent teeth. Although the physiological cause and maxillary sinus pneumatization are largely unknown, it is believed that genetics, atmospheric pressure, and hormones are involved in it. This sinus is closely related to the root apex of the premolar and molar teeth, and it is either separat...
The long-term stability of maxillary sinus floor augmentation with β-TCP remains largely unknown. We report the long-term assessment of volumetric changes in maxillary sinus floor augmentation with β-TCP by cone-beam computed tomography (CBCT).

Successful implant therapy is feasible in patients receiving antiresorptive therapy. The risk of osteonecrosis development needs to be explained to the patient. An individual risk assessment is essential, taking the primary disease with the medication and further wound-healing-compromising diseases and medications into account. If possible, bone augmentations should be avoided, and a perioperative...
The use of bone markers is discussed controversially in the literature, and no clear recommendation can be given at the moment [1, 8]. In these cases, where an implant is planned, a perioperative antimicrobial prophylaxis should be administered, similar to the prophylaxis suggested in other surgical procedures performed in these patients, since this seems to be a tool to decrease BP-ONJ frequency ...
Dental implants can improve the Qol in patients with antiresorptive therapy (bisphosphonate/denosumab) [44] analogous to patients without antiresorptive therapy [48]. A recently performed systematic review on masticatory performance, bite force, nutritional state and patient’s satisfaction showed that implant-supported dentures were associated with high patient satisfaction regarding denture com...
Even latest guidelines and statements dealing with medication associated osteonecrosis of the jaws such as the American [7, 8], Scottish [47], Swiss [6] or German [1] do not address implant therapy in these patients in detail. Due to this lack of data a systematic literature review was performed to fill this gap. Unfortunately the literature dealing with this topic is very sparse and consists main...
No articles could be found regarding the prognosis of the remaining dentition depending on implant therapy, neither for patients with bisphosphonate nor denosumab treatment.
There are no reliable parameters indicating the success of implants in patients with anti-resorptive therapy. The risk of osteonecrosis development has already been described in the chapter referring to the osteonecrosis risk...
The literature dealing with this topic can be separated into two groups:
BP-ONJ case series for which varying amounts are caused by dentures in patients with malignant and benign diseases [2, 33–42] and
studies performed on BP patients with dentures analyzing the frequency of BP-ONJ [15, 43].
Here as well, no imbalance regarding the dignity of the primary disease could be found. Jabbour descr...

A similar scenario is well known in patients with radiation of the jaws. Initially, radiation therapy was seen as a contraindication for implant insertion [14] because of osteoradionecrosis. In Germany meanwhile, implants are covered by the health insurance by law in some of these patients (§28 SGB V Sozialgesetzbuch). Due to xerostomia sufficient fixation of a denture is rather complicated, and ...
Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is a well-known side effect in patients receiving bisphosphonates (BP) due to e.g. osteoporosis, multiple myeloma or malignant diseases with metastases to the bone; prevalences range between 0.1% for patients with primary osteoporosis to 1% in patients with secondary osteoporosis and up to about 20% for special high risk subpopulations o...
Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is triggered by inflammatory processes. Typical trigger factors are periodontal disease, denture pressure sores, and surgical interventions such as tooth extractions. Unfortunately there is only little data on how to proceed with implant therapy in patients with bisphosphonate treatment. This topic is not addressed in the German guidelin...

Soft tissue augmentation with PRF using a split-flap technique cannot be recommended to alter thin gingiva types. Future experimental and clinical studies will be necessary to evaluate whether augmentation with PRF is suitable for mucosa thickening.
With respect to marginal bone loss, it could be shown that there were no significant differences when comparing dimension of bone loss between test and control groups. The study of present research data shows, to the best knowledge of the authors, no other RCTs about tissue thickening with PRF and peri-implant bone loss. However, several studies focused on mucosa thickening with tissue grafts and ...
In this study over a period of 6 months, it could be demonstrated that mucosal tissue thickening above implants with PRF led to reduced tissue thickness when performed in a split-flap technique.
The initial post-operative dehiscence and the associated complete loss of mucosal and augmented tissue above the implant were observed in all test patients.
PRF is supposed to be a good healing aid in v...
The mean marginal bone level alterations are displayed in Fig. 3.
Six months after surgery, both groups showed a statistically significant peri-implant bone loss.
The mesial resp. distal defect depth was 0.70 mm ± 0.72 SD resp. 0.64 mm ± 0.66 SD at baseline. Six months later, the marginal bone defect increased to 1.47 mm ± 0.65 SD on the mesial side resp. 1.46 mm ± 0.54 ...
At time of surgery, the patients ranged in age from 33 to 79 years (mean age 53.8 years).
The first surgeries for implant placement in the test group were carried out as described above. Two layers of a PRF matrix were placed on top of the implant. Though surgical flaps were all sutured completely free of tension, a post-operative dehiscence above the implant could be observed in all test pati...
Comparison of bone level alterations between test and control groups.
Data were expressed as means ± standard deviation. Comparisons were made using the Wilcoxon test, the Mann–Whitney U test, and the multiple comparisons test by Schaich-Hamerle (p = 0.05).
After the implantation, standardized digital X-rays were taken with parallel technique (baseline) (illustration 9). For each patient, an individual customized digital film holder was fabricated to ensure a reproducible radiographic analysis. Patients were instructed to avoid chewing hard nutrition in the treated area and to use chlorhexidine mouthwash and a soft brush twice a day for the first 2 ...

As a consequence, recent research focused on soft tissue augmentation of thin gingiva types prior to or simultaneous to implant insertion. Wiesner et al. published a significant gain of soft tissue by thickening the gingiva with a connective soft tissue graft harvested from the palate [12]. Soft tissues at augmented sites were 1.3 mm thicker than on control sites and had a better pink esthetic sc...
The initial bone modeling around implants within the first year after insertion presents a challenging topic in current research. Previous studies have shown that this process is characterized by a remodeling of the horizontal and vertical bone dimension with a range of 0.7 to 3 mm within the first year [1].
First attempts to reduce this loss of tissue focused on changes of implant shapes, impla...
Previous studies have shown that adequate thickness or initial augmentation of soft tissue has a positive effect on the stability of peri-implant bone. This randomized, controlled trial aimed to evaluate the influence of augmenting soft tissue with platelet-rich fibrin (PRF) on crestal bone and soft tissue around implants.
After randomization, 31 fully threaded titanium implants were inserted in ...

Sinus floor elevation
Our study found that the largest tissue thickening was present in the middle section of the maxillary sinus. This tissue thickening did not vary based on gender, age, or smoking status, nor did it relate to the underlying alveolar ridge height. However, patients with a history of periodontal diseases demonstrated a significant association with mucosal thickening. A mucosal thickening index was pro...
Although residual alveolar ridge height has been associated with sinus mucosal thickening [36], our study did not find a significant association between these two parameters. Acharya et al. [36] reported that lower available bone height in the subsinus region was related to thickened sinus membranes within an Asian-Indian and Hong Kong-based Chinese population. Differences in the ethnic compositio...
Based on the findings of the current study, a history of periodontal disease is the only identified parameter significantly associated with sinus mucosal thickening. This finding indicates that clinicians should expect some degree of mucosal thickening when performing sinus augmentation procedures in a previously periodontally involved site. This finding is consistent with several previously publi...
CBCT imaging has been recognized as a more sensitive imaging modality for identifying sinus thickening and pathoses in the posterior maxilla compared to panoramic radiography [21, 22]. This could explain why the current study identified a higher prevalence of mucosal thickening compared to earlier studies [23]. However, compared to other similar CBCT studies [21, 24, 25], the prevalence reported i...
Twenty-nine CBCT images (11 females and 18 males) were included in this study. All the implants placed in these included cases survived, representing a 100% implant survival rate. With regards to measurements of mucosal thickening, the intra-examiner reproducibility revealed an exact intra-examiner correlation of 99%, with a p value of 0.40 for a t test for independent samples, indicating a high r...
The sites that were measured are specified in the image below (Fig. 1). The most posterior and anterior aspects of the visible maxillary sinus were measured. The ½ point along with the ¼ and ¾ points were then selected, and the measurements of the mucosal thickening were then completed at these three sites. The thickest portion of the mucosa was also measured if it did not coincide with one of...
The study required access to University of Michigan Protected Health Information (PHI). PHI was necessary in order to track and coordinate the CBCT data and dental and medical history for each subject. Corresponding subject charts and electronic records were reviewed for retrieval of relevant implant placement and restorative history, medical history, and demographic information, including gender ...
Our study hypothesis was that mucosal thickening of more than 2 mm and up to 1/3 of the volume of the sinus would not alter the predictability for SFE and dental implant placement. The primary outcome was to determine the success rate of dental implant placement in augmented maxillary sinus areas with mucosal thickening. A secondary outcome was to evaluate the effect of gender, age, and smoking o...
Despite the high survival rate of dental implants inserted in maxillary sinuses that have undergone sinus floor elevation (SFE) with bone grafting, complications still occur [1–3]. Sinus membrane perforation is reported to be the most common complication [4, 5]. Postoperative maxillary sinusitis is less common (0–22%) [6, 7]; nevertheless, it could potentially compromise the outcome of SFE and...
Although mucosal thickening is the most common radiographic finding observed regarding sinus pathology, the knowledge regarding its clinical significance on the outcomes of dental implants and grafting in the maxillary sinuses is still limited. We hypothesized that mucosal thickening would not alter the predictability for sinus floor augmentation and dental implant placement. The purpose of this r...

This case highlights the evolving variations in dentoalveolar augmentation with an emphasis on concomitant implant placement. In the most traditional sense, a vertical osteoperiosteal flap technique would be bound with a stable basal bone that can be used to anchor simultaneous dental implant placement. Further refinement should consider minimizing crestal reflection and overall labial bone resorp...
A critical appraisal of the gingival architecture in the final end point of this case demonstrates some radiolucency through the soft tissue outlining the platform of the Nobel Biocare TiUnite implant. This would lead us to believe that either the transmucosal bone level placement attempt was inaccurate or excessive reflection of the labial tissue has caused some degree of resorption. This is anot...
A suitable alternative surgical management of this particular case might have been to simply perform an alveoloplasty to produce the desired inter-occlusal clearance and proceed with placement of implant and simultaneous direct sinus lift. That would have left more of the apical portion of the implant within the grafted sinus and possibly modified the location of keratinized band of tissue. The lo...
A 35-year-old female with a 10-year history of partial acquired edentulism at site numbers 3 and 4 presented to our clinic for dental implant evaluation. Preoperative clinical examination revealed a reproducible intercuspation, well-delineated band of keratinized tissue, and decreased inter-occlusal clearance to allow for optimal dimension of prosthetic crowns (Fig. 1). Radiographs demonstrated e...
Obtaining proper occlusal clearance to allow for a single unit crown restoration is a fundamental prerequisite for dental implant restoration. Long-standing edentulous sites are often fraught with disuse atrophy and unopposed supra-eruption of the opposing dentition. In the posterior maxillae/mandible, there are vital structures that have to be mobilized in order to allow space for either bone tra...
Dental restorative space from the opposing dentition requires adequate distance for restorative material for an acceptable restoration. Typically, long-standing edentulous alveolar ridges will have vertical and or horizontal defects that require alveolar ridge augmentation for ideal dental implant restorations. Along with these defects, one will see the opposing dentition supra erupt which can obl...

Within the limitations of this study, the results demonstrated a high long-term survival for sinus augmentation procedures and significant improvement of OHRQoL after this procedure. Therefore, sinus augmentation procedures are highly valuable treatment options in implant dentistry.
In order to measure OHRQoL in the present study, a specific and shortened questionnaire based on the validated and reliable OHIP score was developed to consider representative impairments of maxillary sinus augmentation like sinusitis and to relieve the clinical application. In a cross sectional study, Allen et McMillan proofed that a shortened OHIP-14 version showed a similar ability to assess OH...
The clinical and radiological outcomes of sinus augmentation procedures have been published in several studies [1, 3, 6, 7]. However, little data on the physical and psychological impact of this procedure on the patient is available yet. The present study evaluated pre-operative and post-treatment OHRQoL self-assessment scores of patients treated with dental implants after sinus augmentation proce...
Concerning functional limitations, all posed questions showed significant better values for OHRQoL after sinus augmentation procedure than before the treatment (p
After an average time in situ of 41.2 ± 27 months (3.4 years; range 0–96 months), 40 of the 863 implants were lost. These results indicated an in situ rate of 95.4%. One-year and five-year survival rate according to Kaplan–Meier were 95.4 and 94.4%. In patients receiving an external sinus lift an in situ rate of 95.1% and in patients with an internal sinus lift an in situ rate of 96.4%...
The Kaplan–Meier survival function was applied for the description of survival rates. To examine the statistical difference between survival rates, a log-rank test was used. Implant-related data were calculated. For statistical comparison of the paired questions and the total scores, a Wilcoxon test was applied. The intention of this study was descriptive, exploratory without a primary hypothesi...
This retrospective study addresses the oral health-related quality of life after maxillary sinus augmentation. Therefore, all patients that received an implantation after maxillary sinus augmentation in the Department of Oral and Maxillofacial Surgery of the University Medical Centre Mainz, Germany, between July 2002 and December 2007 were included in this study. There were no specific exclusion c...
In conclusion, little information is available about patient’s perception of sinus augmentation procedures. The aim of the present study was to assess whether sinus augmentation procedures together with implant placement and prosthetic rehabilitation improve quality of life in dental patients using a modified German OHIP and to examine the survival rates after this procedure.
Rehabilitation of completely and partial edentulous patients with dental implants has proved to be a safe and predictable procedure [1–3]. However, reduced bone height and the proximity of the maxillary sinus are challenging limitations for dental implant placement in the posterior maxilla [3]. Besides the use of short and tilted implants [4], one of the most frequently used surgical techniques ...
The aim of this study was to measure the oral health-related quality of life (OHRQoL) after maxillary sinus augmentation to determine the physical and psychological impact of this procedure for the patient.

Within the limits of this case series, it has been shown that particulated dentin of autologous teeth may serve as an alternative to autologous bone for alveolar ridge preservation prior to implant therapy. However, randomized studies on this treatment option are necessary.
In humans, particulated tooth material has been used for sinus augmentation in order to enhance implant therapy. Preliminary results from five patients histologically showed an osteoconductive osteogenesis with partial resorption of tooth components [25].
In the present case series, all patients underwent socket preservation with AutoPD. In all cases, one or two upper frontal central incisors wer...
The aim of this case series is to demonstrate the efficacy and safety of this novel augmentative procedure for ridge preservation prior to implant therapy. This shall serve as a basis for a prospective study.

Four months post-extraction and augmentation with autologous, particulated dentin, all four patients received an implant placement in the augmented area. In all cases, a CBCT was taken in between the dentin augmentation and the implant placement.
During implant placement, a biopsy of the bone from the augmented area was taken for histological examination (Fig. 17).

Subsequent to tooth extraction, a resorption of the host bone as defined by atrophy of the alveolar ridge can be observed. Sutton et al. classified the different degrees of alveolar ridge atrophy [32]. Bone resorption especially occurs in the frontal and premolar area of the jaw in the region of the thin buccal lamella. This may lead to a change in contour [11, 28]. Physiological reason for this a...
Ridge preservation can be performed with autologous bone, alloplastic bone substitute material or a combination of both. Dentin is similar to bone in its chemical composition. In its use as bone substitute material, it undergoes a remodelling process and transforms to bone. The presented case report introduces a technique in which the extraction socket is augmented with autologous, particulated de...

In conclusion, segmental mandibular sandwich osteotomy is an easy and safety technique that could be performed in atrophic posterior mandible.
Future studies involving long-term follow-up are needed to evaluate the permanence of these results.
The sandwich technique for bone augmentation of the atrophic mandible was first described by Schettler and Holtermann, with promising results. Since then, variations in this surgical procedure have been proposed by several investigators [4,5,6,7,8,9,10].
All these authors have proposed the same approach about the flap: paracrestal incision. In order to preserve the blood supply, it is of fundamen...

In cases of atrophic mandible, the distance to the mandibular canal and the transverse decrease in bone is an anatomic limitation for prosthetic rehabilitation with dental implants. The gold standard for treatment of this mandibular atrophy continues to be autologous bone grafting [1, 2].
A relatively modern technique for vertical bone augmentation is sandwich osteotomy. Schettler and Holtermann ...
Segmental mandibular sandwich osteotomy is an easy and safety technique that could be performed in an atrophic posterior mandible. Future studies involving long-term follow-up are needed to evaluate the permanence of these results.
A three-dimensionally favourable mandibular bone crest is desirable to be able to successfully implant placement to meet the aesthetic and functional criteria in the implant-prosthetic rehabilitation. Several surgical procedures have been advocated for bone augmentation of the atrophic mandible, and the sandwich osteotomy is one of these techniques. The aim of the present case report was to assess...

The results of the clinical study proves the reliability and low comorbidity of autologous bone grafts in preprosthetic alveolar ridge reconstructions prior to implant insertion.

Data on risk factors based on the original examination and documentation are difficult to assess the adverse effects of variable factors on the surgical prognosis because of the multifactorial genesis of surgical complications [73]. Factors such as gender, age, or smoking habit could be associated with postoperative complications after two-stage dentoalveolar reconstruction with autologous bone gr...
The results of the present study have to take into account the absence of a control group with patients undergoing bone augmentation procedures with bone substitutes (allogen, alloplastic, exogen). Without a comparative group of grafting surgeries using alternative bone material, only limited statements can be made.
However, the excellent surgical outcome of autologous surgical methods providing ...
The use of autologous bone in this study has shown excellent graft survival and success rate (95.6%). This is equal to the results from the studies on implants inserted in reconstructed sites [6, 8, 24]. The early implant survival rate of 99.7% found in the present material is very high comparable to that in the previous systematic reviews after staged horizontal ridge augmentation [9, 10, 22, 62,...
Of the sinus floor elevations performed in this study, 84.8% were defined absolutely successful. Only two of our 72 patients having sinus lift operations could not finally be treated with dental implants. These results are comparable to other studies considering the sinus graft to be a safe treatment modality with few complications [6, 8, 51,52,53]. Raghoebar et al. reported incidences of sinus co...
Postoperative morbidity after mandibular bone harvesting procedures was reported to be mainly related to temporary or permanent neural disturbances involving the inferior alveolar nerve and its branches [19]. In this study, only the incidence of the temporary hypoesthesia of the mandibular and lingual nerve after harvesting from the retromolar area could be detected. It was 10.4 and 2.8%, respecti...
Systematic reviews have failed to find evidence that one particular grafting technique is superior to others [10]. Intraoral bone grafts from the mandibular symphysis, mandibular ramus, and maxillary tuberosity provide a good treatment modality for ridge augmentation, and the amount of bone available for harvesting is sufficient for defects up to the width of three teeth [42]. Harvesting of retrom...
Several grafting procedures have been described to create sufficient volume of bone for implant placement [8, 9]. Autologous bone grafts can be harvested by an intraoral approach (mandibular ramus, mandibular symphysis, zygomatic buttress) or from distant sites (iliac crest, calvaria, and etc.) [17, 36, 37]. However, bone harvesting potentially causes donor site morbidity which is a major issue fo...
The average healing period until implant placement after bone harvesting was 4.53 months. Initially, 546 implants in 279 patients were planned. After the healing period, it was possible to place 525 implants in 436 successfully augmented areas in 259 patients. Three hundred implants were inserted in the maxilla and 225 in the mandible. The remaining 21 implants planned for 20 patients could not b...
Regarding intraoperative complications, all sinus membrane perforations were covered with a resorbable collagen membrane (Bio-Gide®, Geistlich Biomaterials, Baden-Baden, Germany) which applied as sealant to overlap the site of perforation prior to insertion of the graft material. These patients were advised to avoid physical stress, blowing their noses, or sneezing for a period of 3 weeks, and n...
No permanent damage to any trigeminal nerves was evident in any of our entire cohort. All cases of postoperative hypoesthesia of the mental, lingual, or infraorbital nerve were just a temporary nature. At the time of implant surgery, none of these patients reported any persisting neural disturbances (Fig. 4).
In eleven patients, hypoesthesia of the mental area was mentioned, and three of them al...
Thirty-eight patients underwent a total of 116 augmentation procedures harvesting from the iliac crest. In 20 patients, a bone graft augmentation of the maxilla and the mandible in combination with bilateral sinus floor augmentations was performed. Eighteen patients had augmentations only in the maxilla, involving bone grafting and sinus lift elevations. Totally, 76 sinus lifts with bone material ...
In six patients, a partial graft resorption was detected at the time of implantation and an additional simultaneous augmentation with bone chips harvested with the Safescraper device (C.G.M. S.p.A., Divisione Medicale META, Italy) was then necessary in order to ensure the osseointegration of the implants. Two out of these six cases had grafts from the crista zygomatico-alveolaris, two from the ram...
A total of 112 sinus floor elevations were performed. In all of the cases, implants were inserted in a two-stage procedure. The donor site for harvesting the bone for the sinus elevations was in 76 procedures in the iliac crest area, and in 36 procedures, the bone was harvested with a bone scraper device from the lateral sinus wall at the site of sinus lifting.
The distribution and number of tran...
Two hundred seventy-nine patients—250 men and 29 women—underwent 456 augmentation procedures involving autologous bone grafts prior to implant placement. The patients ranged in age from 18.5 to 71.5 years (average 43.1 years) at the moment of augmentation surgery.
Of those patients, 162 (58.1%) were younger than 40 years of age and 117 (41.9%) were older than 40 years of age. Caries or pe...
Early and late implant loss was documented in this study, defining the clinical success of osseointegration. Early implant failures were assessed before the acquisition of osseointegration, i.e., before the placement of prosthodontic restorations. Early implant failure could occur from the time of placement, during the healing phase and before abutment connection. The implant inserted after re-aug...

In addition to the bone already gained with the bone scraper device from the sinus wall during the antrostomy, bone was harvested with the same device from the maxillary buccal buttress, if more volume was needed. By taking this approach, the collection of enough bone for the augmentation of at least two implantation sites was feasible with a mean surgical time of 5 to 10 min for harvesting. In c...
Grafting from the iliac crest was always performed under general anesthesia in a two-team approach. The iliac crest was exposed and autogenous grafts from the anterosuperior inner edge of the iliac wing were harvested with an oscillating saw and/or a chisel, keeping a safe distance of around 2 cm from the anterosuperior iliac spine. After harvesting the bone grafts, the corticocancellous bone blo...
A standardized two-stage surgical protocol was used, and all sites were treated in a similar fashion. In the first intervention, a bone block harvested from the donor site was fixed with osteosynthesis titanium screws to the recipient site as an onlay graft to achieve a horizontal and/or vertical enlargement of the alveolar ridge. Placement of the bone graft was always guided by an augmentation te...
For this retrospective cohort study, we reviewed the records of all patients without exclusion criteria who were referred to the department of oral and plastic maxillofacial surgery at the military hospital of Ulm, Germany, between January 2009 and December 2011 for alveolar ridge augmentations prior to implant insertions using autologous bone grafts harvested from different donor sites and unilat...
In our military outpatient center exclusively, autologous bone transplantations harvested from different donor sites were used intraorally (crista zygomatico-alveolaris, ramus mandible, symphysis mandible, anterior sinus wall) and extraorally (iliac crest) to reconstruct severe horizontal and/or vertical alveolar ridge atrophy prior to implant placement. The aim of this study was to assess the cli...
Although the iliac crest is most often used in jaw reconstruction, a significant bone resorption has been mentioned [12]. This disadvantage, and the fact that dental implants do not always require a large amount of bone, has increased the use of autologous block bone grafts from intraoral sources [13]. Bone grafts from intraoral donor sites offer several benefits like surgical accessibility, proxi...
Oral implantation has a significant role in the rehabilitation of patients. Bone reconstruction techniques have been advanced in order to optimize the esthetic and functional outcome. However, the restoration of the oral function of atrophic alveolar crests still remains a challenge in oral implantology. Bone augmentation procedures are often indicated to allow implant placement in an optimal thre...
This review demonstrates the predictability of autologous bone material in alveolar ridge reconstructions prior to implant insertion, independent from donor and recipient site including even autologous bone chips for sinus elevation. Due to the low harvesting morbidity of autologous bone grafts, the clinical results of our study indicate that autologous bone grafts still remain the “gold standar...
This study assessed the clinical outcomes of graft success rate and early implant survival rate after preprosthetic alveolar ridge reconstruction with autologous bone grafts.

Within the limitations of this clinical study, we may conclude that the use of CCXBB in combination with DBBM particles and a native bilayer collagen membrane for staged lateral bone augmentation in severe atrophic alveolar crests achieved significant horizontal crestal width allowing for staged implant placement in most of the patients. Histological analysis and implant survival records indicate ...
The immune-histochemical results reported expression of osteopontin mainly at the border between mineralized vital bone (MVB) with CCXBB, what coincides with findings from previous reports [38,39,40]. Alkaline phosphatase (ALP) is considered as an early osteoblast differentiation marker [41]. ALP-positive cells were detectable, in all specimens on the periphery of MVB, associated to areas of new b...
When correlating the clinical results and the histological outcomes, there was a positive association between the presence of soft tissue dehiscence with CCXBB exposure and a diminished amount of new mineralized bone (p = 0.06). This lower amount of new bone within the xenogeneic graft suggests a lack of full graft integration and diminished vascular supply, what may have caused the soft tissu...
The purpose of this investigation was to evaluate histologically and immunohistochemically the behavior of CCXBB blocks when used for staged lateral bone augmentation in severe human horizontal residual bone defects. Six months after the regenerative intervention using the CCXBB blocks, the mean increase in bone width was 4.12 mm and hence, this outcome allowed for the placement of dental implant...
The results from the histomorphometric measurements are depicted in Table 2. Bone biopsies were composed by 21.37% (SD 7.36) of residual CCXBB, 26.90% (SD 12.21) of mineralized vital bone (MVB), 47.13% (SD 19.15) of non-mineralized tissue and 0.92% of DBBM (Fig. 5b). Biopsies from patients who lost their implants had a statistical significant lower amount of MVB (p = 0.01u) and a statistical...
Twenty-eight CCXBB blocks were placed in 15 patients that fulfilled the selection criteria (12 women and 3 men) with a mean age of 54.5 (SD 8.34).
The detailed clinical and radiographical outcomes have been reported previously [21]. In brief, one patient experienced pain and soft tissue dehiscence leading to removal of the graft material 3 days after the regenerative procedure. Another patient r...
For the immunohistochemical analysis, the semi-thin sections were incubated over night with primary antibodies at 4 °C (Santa Cruz Biotechnology Inc., Santa Cruz, Calif., USA). The antibody dilutions used were alkaline phosphatase (ALP) 1:100, osteopontin (OPN) 1:100, osteocalcin (OSC) 1:100, and tatrate resistant acid phosphatase (TRAP) 1:100.
The obtained semi-thin sections were evaluated wit...
Twenty-six weeks after the regenerative procedure the patient returned for the re-entry intervention for placement of dental implants. After raising full-thickness flaps, the augmented area was exposed and horizontal crestal width measurements were performed. Then, the surgeon evaluated the bone availability and if implant placement was considered possible, a core bone biopsy was harvested with th...
CCXBB (Bio-Graft® Geistlich Pharma) is a bone substitute material in a natural block form. The dimensions of the Bio-Graft block are 10 mm in height, 10 mm in length and 5 mm in width. It consists of a natural cancellous bone structure of hydroxyapatite and endogenous collagen type I and III, equine origin and is a class III medical device according to the Medical Device Directive 93/42 EECs...
The present manuscript reports the histological outcomes of a prospective single arm study evaluating the safety and clinical performance of CCXBB blocks when used as replacement bone grafts for lateral bone augmentation prior to staged implant placement. The results of the clinical and radiographic outcomes have been reported in a previous publication [21]. For correlation of the histological wit...
Different techniques and grafting materials have been used for the horizontal reconstruction of deficient alveolar processes before implant placement, resulting in different degrees of predictability and clinical outcomes [1]. Among the grafting materials, particulated xenogeneic materials have been extensively studied in both experimental and clinical studies and when combined with porcine-derive...
The osteoconductive properties of collagen containing xenogeneic bone blocks (CCXBB) remain unclear. The aim of this prospective single-arm clinical study was to assess the histological outcomes of CCXBB blocks used as bone replacement grafts for lateral bone augmentation procedures.

Within the limits of this case-controlled study, it can be concluded that lateral ridge augmentation procedures in atrophic alveolar ridges using bioresorbable matrix barriers without achieving primary flap closure or in the case of early exposures can still lead to clinically satisfying ridge width gain that allows for the placement of dental implants. However, exposures seem to limit the ridge w...
The microbial contamination of the matrix barrier during exposure could be another important factor that might hamper bone formation within the underlying graft. This factor has not been investigated in the present study. However, it has been reported by other groups that the resorbable matrix barrier per se might be less prone to bacterial contamination and can be better cleaned using disinfectan...
Although numerous studies in the literature show successful outcomes of the GBR procedure [6, 31], the most common clinical complication in GBR procedures is early membrane exposure [9]. There is a general clinical impression that the ridge augmentation results are compromised in the case of early membrane exposures [32, 33]. In this case-controlled study, which was based on a patient subset from ...
To assess if the baseline situations of the patients in the two treatment groups were comparable and well balanced, the distribution of gender, age, and the initial ridge measurements were compared. There were three women and four men in each group. The median age for the test and control group was 50 and 62 years old, respectively (Table 1). The initial alveolar mean ridge widths before lateral...

Fourteen subjects were retrospectively recruited for this case-controlled study.

Various resorbable membranes exist in the market composing of dura mater, poly-lactic acid, polyglycolic acid, polyurethane, or mostly collagen. Still, even resorbable membranes show frequent events of membrane exposures after GBR procedures. For example, between 22 and 32% of early membrane exposure have been reported for collagen membrane by several authors [15,16,17,18]. A major drawback of col...
It has been reported that unpreserved alveolar ridges can show substantial horizontal and/or vertical ridge deficiency [1, 2] that lack the sufficient alveolar ridge dimensions to allow the ideal positioning of the implant and enhance long-term prognosis of the clinical outcomes [3]. Guided bone regeneration (GBR) is a predictable technique for augmenting the alveolar ridge width that has been use...
The effect of membrane exposure on guided bone regeneration (GBR) for lateral ridge augmentation has been poorly addressed. This case-controlled study aimed to investigate potential effect of membrane exposure lateral ridge augmentation and subsequent implant placement.
A total of 14 patients that did receive lateral ridge augmentation procedure using allogeneic cancellous graft particulate in co...

Based on clinical, radiological, histological, and histomorphometric analysis, this study confirms the suitability of BCP for vertical augmentation of the posterior maxilla by means of an MSFE procedure, allowing dental implant placement after 9 and 12 months healing times. Yet, complete degradation of the BCP particles does not occur within a 12-month healing time. From a histological and histom...
In the cranial part of the biopsy, some osteoid islands with osteogenic activity were detected, possibly caused by osteoinductive properties from the lifted bony trap-door. In the present study, histomorphometric analyses revealed that the vital bone volume was higher in the 9-month healing time group than in the 12-month healing time group, while one would expect to find more newly formed bone in...
This study presents the clinical, radiological, histological and histomorphometric results on the use of a biphasic calcium phosphate (Straumann® bone ceramic) in a MSFE procedure with healing times of 9 and 12 months. During the clinical evaluation, it appeared that both 9-month and 12-month healing times resulted in integration of the grafted BCP with the original maxillary bone (sinus floor),...
Histological observations did not show inflammatory cells in the tissue adjacent to the bone substitute particles. Bone marrow-like tissue, which included blood vessels, was observed in between the bone trabeculae (Fig. 4). Reinforcement by lamellar bone was shown in some areas after 9 and 12 months (Figs. 5 and 6). No Howship’s lacunae could be detected on the characteristic outlines of the su...
None of the 10 patients showed postoperative inflammation or infection after the MSFE procedure nor during surgical re-entry for dental implant placement. When opening the area for dental implant insertion, the grafted area proved to be well vascularized and the tissue at the site of the former trap-door location was slightly flexible and had a fibrous aspect. Between the periosteum and the bone g...

A midcrestal incision was made with vertical release incisions at the canine and tuberosity region. A full-thickness mucoperiosteal flap was elevated. The lateral maxillary sinus wall was prepared using a diamond burr with copious irrigation with sterile isotonic saline, regarding the contour of the maxillary sinus as observed on the preoperative panoramic radiograph. A bony top-hinge trap-door wa...
In this study, 10 consecutive healthy patients were selected for a unilateral MSFE procedure. Five patients received dental implants 9 months after MSFE and five patients underwent dental implant surgery 12 months after MSFE. In the 9-month group (three men and two women), the average age was 56.6 years (range 40 to 64 years); in the 12-month group (one man and four women), the average age was...
β-TCP is a biocompatible osteoconductive calcium phosphate that may provide a scaffold for potential bony ingrowth [24]. β-TCP resorbs rather quickly but not necessarily at the same rate as new bone formation [25,26,27]. Most research focused on either using the relative unresorbable HA as a scaffold or β-TCP as a degradable component [19, 24,25,26, 28, 29]. Zerbo et al. [30] concluded that due...
Maxillary sinus floor elevation (MSFE) is a surgical procedure to enhance the bone height in the posterior maxilla with graft material, allowing dental implant placement (later or at the same time) [1, 2]. This pre-implant procedure is predictable and results in a dental implant survival of more than 93.8% 3 years after dental implant placement [3]. According to Pjetursson [4] in his systematic r...
This study evaluates the clinical, radiological, histological, and histomorphometric aspects of a fully synthetic biphasic calcium phosphate (BCP) (60% hydroxyapatite and 40% ß-tricalcium phosphate), used in a human maxillary sinus floor elevation (MSFE) procedure with 9- and 12-month healing time.

Dental implant placement is an effective treatment method for the replacement of lost teeth with high survival rates after long-term follow-up [1,2,3]. However, the long-term success and stability of implants in function are directly correlated with the quality and quantity of the available bone at the prospective implant site [4, 5]. Despite the development of various techniques and augmentation ...

Sinus floor elevation
Our study found that the largest tissue thickening was present in the middle section of the maxillary sinus. This tissue thickening did not vary based on gender, age, or smoking status, nor did it relate to the underlying alveolar ridge height. However, patients with a history of periodontal diseases demonstrated a significant association with mucosal thickening. A mucosal thickening index was pro...
Although residual alveolar ridge height has been associated with sinus mucosal thickening [36], our study did not find a significant association between these two parameters. Acharya et al. [36] reported that lower available bone height in the subsinus region was related to thickened sinus membranes within an Asian-Indian and Hong Kong-based Chinese population. Differences in the ethnic compositio...
Based on the findings of the current study, a history of periodontal disease is the only identified parameter significantly associated with sinus mucosal thickening. This finding indicates that clinicians should expect some degree of mucosal thickening when performing sinus augmentation procedures in a previously periodontally involved site. This finding is consistent with several previously publi...
CBCT imaging has been recognized as a more sensitive imaging modality for identifying sinus thickening and pathoses in the posterior maxilla compared to panoramic radiography [21, 22]. This could explain why the current study identified a higher prevalence of mucosal thickening compared to earlier studies [23]. However, compared to other similar CBCT studies [21, 24, 25], the prevalence reported i...
Twenty-nine CBCT images (11 females and 18 males) were included in this study. All the implants placed in these included cases survived, representing a 100% implant survival rate. With regards to measurements of mucosal thickening, the intra-examiner reproducibility revealed an exact intra-examiner correlation of 99%, with a p value of 0.40 for a t test for independent samples, indicating a high r...
The sites that were measured are specified in the image below (Fig. 1). The most posterior and anterior aspects of the visible maxillary sinus were measured. The ½ point along with the ¼ and ¾ points were then selected, and the measurements of the mucosal thickening were then completed at these three sites. The thickest portion of the mucosa was also measured if it did not coincide with one of...
The study required access to University of Michigan Protected Health Information (PHI). PHI was necessary in order to track and coordinate the CBCT data and dental and medical history for each subject. Corresponding subject charts and electronic records were reviewed for retrieval of relevant implant placement and restorative history, medical history, and demographic information, including gender ...
Our study hypothesis was that mucosal thickening of more than 2 mm and up to 1/3 of the volume of the sinus would not alter the predictability for SFE and dental implant placement. The primary outcome was to determine the success rate of dental implant placement in augmented maxillary sinus areas with mucosal thickening. A secondary outcome was to evaluate the effect of gender, age, and smoking o...
Despite the high survival rate of dental implants inserted in maxillary sinuses that have undergone sinus floor elevation (SFE) with bone grafting, complications still occur [1–3]. Sinus membrane perforation is reported to be the most common complication [4, 5]. Postoperative maxillary sinusitis is less common (0–22%) [6, 7]; nevertheless, it could potentially compromise the outcome of SFE and...
Although mucosal thickening is the most common radiographic finding observed regarding sinus pathology, the knowledge regarding its clinical significance on the outcomes of dental implants and grafting in the maxillary sinuses is still limited. We hypothesized that mucosal thickening would not alter the predictability for sinus floor augmentation and dental implant placement. The purpose of this r...

This case highlights the evolving variations in dentoalveolar augmentation with an emphasis on concomitant implant placement. In the most traditional sense, a vertical osteoperiosteal flap technique would be bound with a stable basal bone that can be used to anchor simultaneous dental implant placement. Further refinement should consider minimizing crestal reflection and overall labial bone resorp...
A critical appraisal of the gingival architecture in the final end point of this case demonstrates some radiolucency through the soft tissue outlining the platform of the Nobel Biocare TiUnite implant. This would lead us to believe that either the transmucosal bone level placement attempt was inaccurate or excessive reflection of the labial tissue has caused some degree of resorption. This is anot...
A suitable alternative surgical management of this particular case might have been to simply perform an alveoloplasty to produce the desired inter-occlusal clearance and proceed with placement of implant and simultaneous direct sinus lift. That would have left more of the apical portion of the implant within the grafted sinus and possibly modified the location of keratinized band of tissue. The lo...
A 35-year-old female with a 10-year history of partial acquired edentulism at site numbers 3 and 4 presented to our clinic for dental implant evaluation. Preoperative clinical examination revealed a reproducible intercuspation, well-delineated band of keratinized tissue, and decreased inter-occlusal clearance to allow for optimal dimension of prosthetic crowns (Fig. 1). Radiographs demonstrated e...
Obtaining proper occlusal clearance to allow for a single unit crown restoration is a fundamental prerequisite for dental implant restoration. Long-standing edentulous sites are often fraught with disuse atrophy and unopposed supra-eruption of the opposing dentition. In the posterior maxillae/mandible, there are vital structures that have to be mobilized in order to allow space for either bone tra...
Dental restorative space from the opposing dentition requires adequate distance for restorative material for an acceptable restoration. Typically, long-standing edentulous alveolar ridges will have vertical and or horizontal defects that require alveolar ridge augmentation for ideal dental implant restorations. Along with these defects, one will see the opposing dentition supra erupt which can obl...

Within the limits of this case series, it has been shown that particulated dentin of autologous teeth may serve as an alternative to autologous bone for alveolar ridge preservation prior to implant therapy. However, randomized studies on this treatment option are necessary.
In humans, particulated tooth material has been used for sinus augmentation in order to enhance implant therapy. Preliminary results from five patients histologically showed an osteoconductive osteogenesis with partial resorption of tooth components [25].
In the present case series, all patients underwent socket preservation with AutoPD. In all cases, one or two upper frontal central incisors wer...
The aim of this case series is to demonstrate the efficacy and safety of this novel augmentative procedure for ridge preservation prior to implant therapy. This shall serve as a basis for a prospective study.
In all four cases, patients showed a stable volume of soft and hard tissues after the augmentation with AutoPD and good osseointegration of titanium implants, having been placed in this augm...
Four months post-extraction and augmentation with autologous, particulated dentin, all four patients received an implant placement in the augmented area. In all cases, a CBCT was taken in between the dentin augmentation and the implant placement.
During implant placement, a biopsy of the bone from the augmented area was taken for histological examination (Fig. 17).
The final prosthetic solution...
The 1-year follow-up examination of the presented case showed an implant success, according to the appropriate clinical criteria [2] (Figs. 14, 15 and 16).
The pink esthetic score (PES) was used for the evaluation of reproducible soft tissue around the final implant crown as a parameter for the aesthetic outcome [12]. Seven variables were evaluated comparing the soft tissue around the implant wi...
An autologous soft tissue graft was harvested from the patient’s palate using a soft tissue punch (Biopsy Punch, kai Europe GmbH, Solingen, Germany) (Fig. 9). The graft had a comparable dimension as the recipient site. The gingival graft was placed on top of the augmentation material, adapted and carefully sutured to the marginal gingiva after the sulcus epithelium was removed with a rotating d...
Four patients between 36 and 65 years of age are presented in this case series. There was no financial compensation. All four patients suffered from a trauma, causing damage to one or two teeth of the anterior maxilla. The frontal tooth/teeth has/had to be extracted. The pulp of the extracted teeth of three patients and the root canal filling of one patient had to be removed. All patients were in...
Subsequent to tooth extraction, a resorption of the host bone as defined by atrophy of the alveolar ridge can be observed. Sutton et al. classified the different degrees of alveolar ridge atrophy [32]. Bone resorption especially occurs in the frontal and premolar area of the jaw in the region of the thin buccal lamella. This may lead to a change in contour [11, 28]. Physiological reason for this a...
Ridge preservation can be performed with autologous bone, alloplastic bone substitute material or a combination of both. Dentin is similar to bone in its chemical composition. In its use as bone substitute material, it undergoes a remodelling process and transforms to bone. The presented case report introduces a technique in which the extraction socket is augmented with autologous, particulated de...

In conclusion, segmental mandibular sandwich osteotomy is an easy and safety technique that could be performed in atrophic posterior mandible.
Future studies involving long-term follow-up are needed to evaluate the permanence of these results.
The sandwich technique for bone augmentation of the atrophic mandible was first described by Schettler and Holtermann, with promising results. Since then, variations in this surgical procedure have been proposed by several investigators [4,5,6,7,8,9,10].
All these authors have proposed the same approach about the flap: paracrestal incision. In order to preserve the blood supply, it is of fundamen...
A 59-year-old woman with a severely atrophied right mandible was treated with the sandwich osteotomy technique filled with autologous bone graft harvested by a cortical bone collector from the ramus.

In cases of atrophic mandible, the distance to the mandibular canal and the transverse decrease in bone is an anatomic limitation for prosthetic rehabilitation with dental implants. The gold standard for treatment of this mandibular atrophy continues to be autologous bone grafting [1, 2].
A relatively modern technique for vertical bone augmentation is sandwich osteotomy. Schettler and Holtermann ...
Segmental mandibular sandwich osteotomy is an easy and safety technique that could be performed in an atrophic posterior mandible. Future studies involving long-term follow-up are needed to evaluate the permanence of these results.
A three-dimensionally favourable mandibular bone crest is desirable to be able to successfully implant placement to meet the aesthetic and functional criteria in the implant-prosthetic rehabilitation. Several surgical procedures have been advocated for bone augmentation of the atrophic mandible, and the sandwich osteotomy is one of these techniques. The aim of the present case report was to assess...

The results of the clinical study proves the reliability and low comorbidity of autologous bone grafts in preprosthetic alveolar ridge reconstructions prior to implant insertion.

Data on risk factors based on the original examination and documentation are difficult to assess the adverse effects of variable factors on the surgical prognosis because of the multifactorial genesis of surgical complications [73]. Factors such as gender, age, or smoking habit could be associated with postoperative complications after two-stage dentoalveolar reconstruction with autologous bone gr...
The results of the present study have to take into account the absence of a control group with patients undergoing bone augmentation procedures with bone substitutes (allogen, alloplastic, exogen). Without a comparative group of grafting surgeries using alternative bone material, only limited statements can be made.
However, the excellent surgical outcome of autologous surgical methods providing ...
The use of autologous bone in this study has shown excellent graft survival and success rate (95.6%). This is equal to the results from the studies on implants inserted in reconstructed sites [6, 8, 24]. The early implant survival rate of 99.7% found in the present material is very high comparable to that in the previous systematic reviews after staged horizontal ridge augmentation [9, 10, 22, 62,...
Of the sinus floor elevations performed in this study, 84.8% were defined absolutely successful. Only two of our 72 patients having sinus lift operations could not finally be treated with dental implants. These results are comparable to other studies considering the sinus graft to be a safe treatment modality with few complications [6, 8, 51,52,53]. Raghoebar et al. reported incidences of sinus co...
Postoperative morbidity after mandibular bone harvesting procedures was reported to be mainly related to temporary or permanent neural disturbances involving the inferior alveolar nerve and its branches [19]. In this study, only the incidence of the temporary hypoesthesia of the mandibular and lingual nerve after harvesting from the retromolar area could be detected. It was 10.4 and 2.8%, respecti...
Systematic reviews have failed to find evidence that one particular grafting technique is superior to others [10]. Intraoral bone grafts from the mandibular symphysis, mandibular ramus, and maxillary tuberosity provide a good treatment modality for ridge augmentation, and the amount of bone available for harvesting is sufficient for defects up to the width of three teeth [42]. Harvesting of retrom...
Several grafting procedures have been described to create sufficient volume of bone for implant placement [8, 9]. Autologous bone grafts can be harvested by an intraoral approach (mandibular ramus, mandibular symphysis, zygomatic buttress) or from distant sites (iliac crest, calvaria, and etc.) [17, 36, 37]. However, bone harvesting potentially causes donor site morbidity which is a major issue fo...
The surgical outcome after augmentation and implantation procedures is presented in Fig. 5.
The average healing period until implant placement after bone harvesting was 4.53 months. Initially, 546 implants in 279 patients were planned. After the healing period, it was possible to place 525 implants in 436 successfully augmented areas in 259 patients. Three hundred implants were inserted in the maxilla and 225 in the mandible. The remaining 21 implants planned for 20 patients could not b...
Regarding intraoperative complications, all sinus membrane perforations were covered with a resorbable collagen membrane (Bio-Gide®, Geistlich Biomaterials, Baden-Baden, Germany) which applied as sealant to overlap the site of perforation prior to insertion of the graft material. These patients were advised to avoid physical stress, blowing their noses, or sneezing for a period of 3 weeks, and n...
No permanent damage to any trigeminal nerves was evident in any of our entire cohort. All cases of postoperative hypoesthesia of the mental, lingual, or infraorbital nerve were just a temporary nature. At the time of implant surgery, none of these patients reported any persisting neural disturbances (Fig. 4).
In eleven patients, hypoesthesia of the mental area was mentioned, and three of them al...
Thirty-eight patients underwent a total of 116 augmentation procedures harvesting from the iliac crest. In 20 patients, a bone graft augmentation of the maxilla and the mandible in combination with bilateral sinus floor augmentations was performed. Eighteen patients had augmentations only in the maxilla, involving bone grafting and sinus lift elevations. Totally, 76 sinus lifts with bone material ...
A total of 104 retromolar bone graft procedures in 86 patients were conducted. Twenty-two harvesting procedures were performed for augmentation of the maxilla and 82 for the mandible. Seven retromolar bone grafts (93.2%) in seven single-tooth gap dental regions by seven patients had been lost. Therefore, seven implants could not be inserted in augmented alveolar sites after graft failure. Three of...
In six patients, a partial graft resorption was detected at the time of implantation and an additional simultaneous augmentation with bone chips harvested with the Safescraper device (C.G.M. S.p.A., Divisione Medicale META, Italy) was then necessary in order to ensure the osseointegration of the implants. Two out of these six cases had grafts from the crista zygomatico-alveolaris, two from the ram...
A total of 112 sinus floor elevations were performed. In all of the cases, implants were inserted in a two-stage procedure. The donor site for harvesting the bone for the sinus elevations was in 76 procedures in the iliac crest area, and in 36 procedures, the bone was harvested with a bone scraper device from the lateral sinus wall at the site of sinus lifting.
The distribution and number of tran...
Two hundred seventy-nine patients—250 men and 29 women—underwent 456 augmentation procedures involving autologous bone grafts prior to implant placement. The patients ranged in age from 18.5 to 71.5 years (average 43.1 years) at the moment of augmentation surgery.
Of those patients, 162 (58.1%) were younger than 40 years of age and 117 (41.9%) were older than 40 years of age. Caries or pe...
Early and late implant loss was documented in this study, defining the clinical success of osseointegration. Early implant failures were assessed before the acquisition of osseointegration, i.e., before the placement of prosthodontic restorations. Early implant failure could occur from the time of placement, during the healing phase and before abutment connection. The implant inserted after re-aug...

In addition to the bone already gained with the bone scraper device from the sinus wall during the antrostomy, bone was harvested with the same device from the maxillary buccal buttress, if more volume was needed. By taking this approach, the collection of enough bone for the augmentation of at least two implantation sites was feasible with a mean surgical time of 5 to 10 min for harvesting. In c...
Grafting from the iliac crest was always performed under general anesthesia in a two-team approach. The iliac crest was exposed and autogenous grafts from the anterosuperior inner edge of the iliac wing were harvested with an oscillating saw and/or a chisel, keeping a safe distance of around 2 cm from the anterosuperior iliac spine. After harvesting the bone grafts, the corticocancellous bone blo...
A standardized two-stage surgical protocol was used, and all sites were treated in a similar fashion. In the first intervention, a bone block harvested from the donor site was fixed with osteosynthesis titanium screws to the recipient site as an onlay graft to achieve a horizontal and/or vertical enlargement of the alveolar ridge. Placement of the bone graft was always guided by an augmentation te...
For this retrospective cohort study, we reviewed the records of all patients without exclusion criteria who were referred to the department of oral and plastic maxillofacial surgery at the military hospital of Ulm, Germany, between January 2009 and December 2011 for alveolar ridge augmentations prior to implant insertions using autologous bone grafts harvested from different donor sites and unilat...
In our military outpatient center exclusively, autologous bone transplantations harvested from different donor sites were used intraorally (crista zygomatico-alveolaris, ramus mandible, symphysis mandible, anterior sinus wall) and extraorally (iliac crest) to reconstruct severe horizontal and/or vertical alveolar ridge atrophy prior to implant placement. The aim of this study was to assess the cli...
Although the iliac crest is most often used in jaw reconstruction, a significant bone resorption has been mentioned [12]. This disadvantage, and the fact that dental implants do not always require a large amount of bone, has increased the use of autologous block bone grafts from intraoral sources [13]. Bone grafts from intraoral donor sites offer several benefits like surgical accessibility, proxi...
Oral implantation has a significant role in the rehabilitation of patients. Bone reconstruction techniques have been advanced in order to optimize the esthetic and functional outcome. However, the restoration of the oral function of atrophic alveolar crests still remains a challenge in oral implantology. Bone augmentation procedures are often indicated to allow implant placement in an optimal thre...
This review demonstrates the predictability of autologous bone material in alveolar ridge reconstructions prior to implant insertion, independent from donor and recipient site including even autologous bone chips for sinus elevation. Due to the low harvesting morbidity of autologous bone grafts, the clinical results of our study indicate that autologous bone grafts still remain the “gold standar...
This study assessed the clinical outcomes of graft success rate and early implant survival rate after preprosthetic alveolar ridge reconstruction with autologous bone grafts.

The immune-histochemical results reported expression of osteopontin mainly at the border between mineralized vital bone (MVB) with CCXBB, what coincides with findings from previous reports [38,39,40]. Alkaline phosphatase (ALP) is considered as an early osteoblast differentiation marker [41]. ALP-positive cells were detectable, in all specimens on the periphery of MVB, associated to areas of new b...
When correlating the clinical results and the histological outcomes, there was a positive association between the presence of soft tissue dehiscence with CCXBB exposure and a diminished amount of new mineralized bone (p = 0.06). This lower amount of new bone within the xenogeneic graft suggests a lack of full graft integration and diminished vascular supply, what may have caused the soft tissu...
The purpose of this investigation was to evaluate histologically and immunohistochemically the behavior of CCXBB blocks when used for staged lateral bone augmentation in severe human horizontal residual bone defects. Six months after the regenerative intervention using the CCXBB blocks, the mean increase in bone width was 4.12 mm and hence, this outcome allowed for the placement of dental implant...
The results from the histomorphometric measurements are depicted in Table 2. Bone biopsies were composed by 21.37% (SD 7.36) of residual CCXBB, 26.90% (SD 12.21) of mineralized vital bone (MVB), 47.13% (SD 19.15) of non-mineralized tissue and 0.92% of DBBM (Fig. 5b). Biopsies from patients who lost their implants had a statistical significant lower amount of MVB (p = 0.01u) and a statistical...
Twenty-eight CCXBB blocks were placed in 15 patients that fulfilled the selection criteria (12 women and 3 men) with a mean age of 54.5 (SD 8.34).
The detailed clinical and radiographical outcomes have been reported previously [21]. In brief, one patient experienced pain and soft tissue dehiscence leading to removal of the graft material 3 days after the regenerative procedure. Another patient r...
For the immunohistochemical analysis, the semi-thin sections were incubated over night with primary antibodies at 4 °C (Santa Cruz Biotechnology Inc., Santa Cruz, Calif., USA). The antibody dilutions used were alkaline phosphatase (ALP) 1:100, osteopontin (OPN) 1:100, osteocalcin (OSC) 1:100, and tatrate resistant acid phosphatase (TRAP) 1:100.
The obtained semi-thin sections were evaluated wit...
Twenty-six weeks after the regenerative procedure the patient returned for the re-entry intervention for placement of dental implants. After raising full-thickness flaps, the augmented area was exposed and horizontal crestal width measurements were performed. Then, the surgeon evaluated the bone availability and if implant placement was considered possible, a core bone biopsy was harvested with th...
CCXBB (Bio-Graft® Geistlich Pharma) is a bone substitute material in a natural block form. The dimensions of the Bio-Graft block are 10 mm in height, 10 mm in length and 5 mm in width. It consists of a natural cancellous bone structure of hydroxyapatite and endogenous collagen type I and III, equine origin and is a class III medical device according to the Medical Device Directive 93/42 EECs...
The present manuscript reports the histological outcomes of a prospective single arm study evaluating the safety and clinical performance of CCXBB blocks when used as replacement bone grafts for lateral bone augmentation prior to staged implant placement. The results of the clinical and radiographic outcomes have been reported in a previous publication [21]. For correlation of the histological wit...
Different techniques and grafting materials have been used for the horizontal reconstruction of deficient alveolar processes before implant placement, resulting in different degrees of predictability and clinical outcomes [1]. Among the grafting materials, particulated xenogeneic materials have been extensively studied in both experimental and clinical studies and when combined with porcine-derive...
The osteoconductive properties of collagen containing xenogeneic bone blocks (CCXBB) remain unclear. The aim of this prospective single-arm clinical study was to assess the histological outcomes of CCXBB blocks used as bone replacement grafts for lateral bone augmentation procedures.
In 15 patients with severe horizontal alveolar ridge resorption, lateral augmentation procedures were performed us...

Within the limits of this case-controlled study, it can be concluded that lateral ridge augmentation procedures in atrophic alveolar ridges using bioresorbable matrix barriers without achieving primary flap closure or in the case of early exposures can still lead to clinically satisfying ridge width gain that allows for the placement of dental implants. However, exposures seem to limit the ridge w...
The microbial contamination of the matrix barrier during exposure could be another important factor that might hamper bone formation within the underlying graft. This factor has not been investigated in the present study. However, it has been reported by other groups that the resorbable matrix barrier per se might be less prone to bacterial contamination and can be better cleaned using disinfectan...
Although numerous studies in the literature show successful outcomes of the GBR procedure [6, 31], the most common clinical complication in GBR procedures is early membrane exposure [9]. There is a general clinical impression that the ridge augmentation results are compromised in the case of early membrane exposures [32, 33]. In this case-controlled study, which was based on a patient subset from ...
To assess if the baseline situations of the patients in the two treatment groups were comparable and well balanced, the distribution of gender, age, and the initial ridge measurements were compared. There were three women and four men in each group. The median age for the test and control group was 50 and 62 years old, respectively (Table 1). The initial alveolar mean ridge widths before lateral...
Means ± SD was calculated for all parameters. The statistical significance difference of means between the groups was tested using an exact two-sample Fisher-Pitman permutation test; since the sample size seemed too small to test for normality, p
Fourteen subjects were retrospectively recruited for this case-controlled study. In test group (seven patients), primary closure was not achieved and membrane was left exposed at the initial surgery or it became exposed during the first week of healing. In the control group (seven patients), primary wound closure was achieved and no exposure of the membrane occurred until the placement of a dental...
Various resorbable membranes exist in the market composing of dura mater, poly-lactic acid, polyglycolic acid, polyurethane, or mostly collagen. Still, even resorbable membranes show frequent events of membrane exposures after GBR procedures. For example, between 22 and 32% of early membrane exposure have been reported for collagen membrane by several authors [15,16,17,18]. A major drawback of col...
It has been reported that unpreserved alveolar ridges can show substantial horizontal and/or vertical ridge deficiency [1, 2] that lack the sufficient alveolar ridge dimensions to allow the ideal positioning of the implant and enhance long-term prognosis of the clinical outcomes [3]. Guided bone regeneration (GBR) is a predictable technique for augmenting the alveolar ridge width that has been use...
The effect of membrane exposure on guided bone regeneration (GBR) for lateral ridge augmentation has been poorly addressed. This case-controlled study aimed to investigate potential effect of membrane exposure lateral ridge augmentation and subsequent implant placement.

Based on clinical, radiological, histological, and histomorphometric analysis, this study confirms the suitability of BCP for vertical augmentation of the posterior maxilla by means of an MSFE procedure, allowing dental implant placement after 9 and 12 months healing times. Yet, complete degradation of the BCP particles does not occur within a 12-month healing time. From a histological and histom...
In the cranial part of the biopsy, some osteoid islands with osteogenic activity were detected, possibly caused by osteoinductive properties from the lifted bony trap-door. In the present study, histomorphometric analyses revealed that the vital bone volume was higher in the 9-month healing time group than in the 12-month healing time group, while one would expect to find more newly formed bone in...
This study presents the clinical, radiological, histological and histomorphometric results on the use of a biphasic calcium phosphate (Straumann® bone ceramic) in a MSFE procedure with healing times of 9 and 12 months. During the clinical evaluation, it appeared that both 9-month and 12-month healing times resulted in integration of the grafted BCP with the original maxillary bone (sinus floor),...
Histological observations did not show inflammatory cells in the tissue adjacent to the bone substitute particles. Bone marrow-like tissue, which included blood vessels, was observed in between the bone trabeculae (Fig. 4). Reinforcement by lamellar bone was shown in some areas after 9 and 12 months (Figs. 5 and 6). No Howship’s lacunae could be detected on the characteristic outlines of the su...
None of the 10 patients showed postoperative inflammation or infection after the MSFE procedure nor during surgical re-entry for dental implant placement. When opening the area for dental implant insertion, the grafted area proved to be well vascularized and the tissue at the site of the former trap-door location was slightly flexible and had a fibrous aspect. Between the periosteum and the bone g...

β-TCP is a biocompatible osteoconductive calcium phosphate that may provide a scaffold for potential bony ingrowth [24]. β-TCP resorbs rather quickly but not necessarily at the same rate as new bone formation [25,26,27]. Most research focused on either using the relative unresorbable HA as a scaffold or β-TCP as a degradable component [19, 24,25,26, 28, 29]. Zerbo et al. [30] concluded that due...
Maxillary sinus floor elevation (MSFE) is a surgical procedure to enhance the bone height in the posterior maxilla with graft material, allowing dental implant placement (later or at the same time) [1, 2]. This pre-implant procedure is predictable and results in a dental implant survival of more than 93.8% 3 years after dental implant placement [3]. According to Pjetursson [4] in his systematic r...

Within the limitations of this study, being retrospective and having no control group, the results show that individualized CAD-CAM-produced titanium meshes are a safe and predictable procedure for large vertical and horizontal ridge augmentations. The soft tissue covering remains one of the most critical steps using this technique. However, exposure of the mesh does not result in complete loss of...
The results showed that in all 21 augmented sites, a significant ridge augmentation was achieved, with a mean vertical augmentation of 6.5 ± 1.7 mm and a mean horizontal augmentation of 5.5 ± 1.9 mm. To our best knowledge, this is the first study investigating these parameters in individualized CAD-CAM-produced titanium meshes. For conventional titanium meshes, several studies were publish...
In our study, PRF membranes were additionally to collagen membranes used to cover the CAD-CAM mesh. The aim of this clinical approach was to improve and accelerate wound healing.

Sinus floor elevation surgery with balloon is said to be a minimally invasive technique [5], but to date, no systematic review was made to clearly present the study results, authors experience, and surgical outcomes. Results of studies that utilized MIAMBE technique could be discussed under these highlighted points.
There are two critical points in sinus floor elevation surgery which include entr...
The total electronic search results were 5395 articles. The reviewed articles were 400, and the extracted articles which involved utilization of balloon technique in the maxillary sinus floor elevation surgery were 27 articles. Siventen articles were excluded from this study [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20] and only 10 articles met the inclusion criteria.

Several sinus floor elevation techniques had been introduced as a minimally invasive surgical procedure. Among which, minimally invasive antral membrane balloon elevation technique was developed to achieve better results with minimal trauma to the patient also to reduce complications and intra-operative time. Conventionally, sinus augmentation procedure is performed either via lateral approach (mo...
Minimally invasive antral membrane balloon elevation was introduced as a less traumatic technique in sinus floor elevation surgery. This is the first systematic review to assess the results of previous studies utilizing this technique.
The objectives of this study were to assess the bone gain, sinus augmentation success rate, implant survival rate, and complications with minimally invasive antral...

In conclusion and within its limitations, the present clinical study revealed that TR grafts may be associated with improved SA26 values following lateral alveolar ridge augmentation.
When further analyzing the present data, it was also noted that both TR and AB grafts were associated with comparable BI26 values, thus corroborating the clinical observation of a firm graft connection to the host bone at 26 weeks, which allowed for a proper placement of adequately dimensioned titanium implants at all sites investigated [9]. The regression analysis also revealed that BI26 values ...
The present analysis aimed at assessing and comparing CBCT outcomes following lateral alveolar ridge augmentation using TR and AB grafts. After a healing period of 26 weeks, it was observed that TR grafts were associated with significantly higher mean SA26 values when compared with the AB group. A similar tendency was also noted for mean BI26 values; however, this difference did not reach statist...
Mean CWb and GT values were comparable in both groups and amounted to 4.53 ± 1.54 mm (median 4.50; 95% CI 3.68, 5.38) and 5.66 ± 1.75 mm (median 5.0; 95% CI 4.69, 6.64) in the TR group and 5.26 ± 1.25 mm (median 5.00; 95% CI 4.57, 5.95) and 4.96 ± 1.75 mm (median 5.0; 95% CI 4.24, 5.68) in the AB group, respectively.

In brief, lateral ridge augment...
Autogenous bone (AB) blocks harvested from intraoral donor sites (i.e., retromandibular, chin) are the most commonly used procedure for lateral alveolar ridge augmentation [1]. However, despite significant horizontal bone gains, cortical bone blocks were noted to undergo an incomplete replacement resorption [2, 3], thus featuring a composition of non-vital residual and newly formed vital bone in t...

A minor, but statistically significant, radiographic bone loss occurred from baseline to the final follow-up at the neighbouring tooth surfaces in both groups. Moreover, both groups experienced a minor recession of the marginal gingiva from baseline to the final follow-up, but the change was not significant. Recession and the bone level of the neighbouring tooth surfaces to implants placed in ...
The combination of the NobelParallel CC implant launched in 2015 and an abutment with ASC is relatively new and has so far been lined to only few mechanical problems [39, 40], among which rotation of the crown when torqueing the abutment screw was not stated. In both patients, a new implant was placed without any need for additional bone augmentation and without further complications. ...
Discussion
The present study focused on clinical and radiographic characteristics of staged implants placed in autogenous bone grafts covered by either a PRF membrane (PRF group) or a standard procedure (gold standard) involving coverage of the autogenous bone graft using a deproteinised bovine bone mineral and a resorbable collagen membrane (control group).
The PRF group demonstrated a hi...
One patient (control group) expressed minimally changed extraoral sensation in the chin region at both the 1- and 2-week follow-up. However, the extra- and intraoral clinical examination revealed no sensory disturbances. The patient was not affected by this and described the same changed sensation at the final clinical follow-up after 29 months.
Another patient (PRF group) experienced sensory d...
Radiographic peri-implant marginal bone change
The mean peri-implant marginal bone level at the different time points is shown in Table 2 and Fig. 2. The mean marginal bone level at follow-up was 0.26 mm (95% CI: 0.01–0.50 mm) in the PRF group and 0.68 mm (95% CI: 0.41–0.96 mm) in the control group. The difference between the groups was − 0.43 mm (95% CI: − 0.80 to − 0....
Bleeding on probing
The estimated probability or observed proportion of BOP for implants was 0.31 (95% CI: 0.14–0.70) in the PRF group and 0.30 (95% CI: 0.12–0.77) in the control group. The ratio of the probability of observing BOP was 1.046 (95% CI: 0.91–1.20), indicating that the probability of observing BOP is 4.6% higher in the PRF group than in the control group. No statistical differe...

Implant survival
Two of the 27 initially placed implants were lost in the control group (Table 1). Twenty months after placement of the implant-supported crown, one implant (first premolar, regular platform (4.3 mm), length: 13 mm) was lost due to failed osseointegration. No periodontitis or peri-implant marginal bone resorption was obvious at the time of implant removal. A second...
The distance from the implant-abutment connection to the peri-implant marginal bone level was measured mesially and distally in parallel with the long axis of the implant using open-source software (ImageJ, National Institutes of Health, Bethesda, MD, USA). The distance from the cemento-enamel junction to the marginal bone level at the neighbouring tooth surfaces was also measured in parallel with...
Prosthodontic treatment
Forty-nine days (range: 27–113 days) after placement of the healing abutment, the abutment was removed and the implant position was registered by an impression coping on the implant.

The bone graft was retrieved by making a continuous osteotomy line with a cylindrical and a round bur at the lateral part of the mandible, with a uniform size of approximately 15 × 25 mm (Fig. 1c, d). The bone block containing mainly cortical bone was then gently separated from the mandible using a raspartorium. The block graft was covered with a saline-moistened gauze until used. In the PRF g...
At the time of the bone augmentation procedure, two patients (14%) in the PRF group and one (8%) patient in the control group were smokers. Patients were partially edentulous due to trauma (n = 22), agenesis (n = 3) or marginal periodontitis [2]. Two patients were unavailable for the final follow-up. The referring dentist followed the non-attenders, and telephone interview revealed no subjective o...
Material and methods
The study was performed according to the Declaration of Helsinki and internationally accepted guidelines for RCT, including the CONSORT statement (www.consort-statement.org). The volumetric changes of the augmented bone [26], the histological composition of the augmented bone [27] and pain after the primary bone augmentation procedure [28] were previously described in d...
Despite the shape of a membrane, the PRF membrane does not have the properties of a resorbable barrier membrane [21, 22], due to its fast degradation in the same manner as a natural blood clot (1–2 weeks) [23]. Therefore, the PRF membrane is not believed to replace a barrier membrane in the classic understanding of guide bone regeneration (GBR), but rather to enhance the healing capacity of t...
Background

In addition, Buch et al. compared the different criteria proposed for implant success with regard to their clinical value. The authors demonstrated that the proposed criteria led to very different success rates 6 years after implant insertion (75–89%) and did not allow reliable comparison of the results with each other. Thus, during control visits in our practices, only prosthetic complica...
The most often used graft material in our evaluation was Geistlich Bio-Oss (53.0%) followed by autogenous bone (32.5%). When compared to no graft, the use of both grafts resulted in significantly higher implant survival rates. In various studies, the bone substitute was found to promote bone regeneration and to allow for long-term stability of the augmented volume. A recent meta-analysis com...
However, there are also a few clinical studies in which reduced survival rates for implants inserted in grafted areas were found. Differences in numbers of implants analysed, surgical techniques, indications and/or graft materials may account for these inconsistent results and further studies might be needed.
In the retrospective analysis shown here, the comparison of different augmentation...
Discussion
The retrospective analysis presented here evaluates implants inserted in three different private practices with or without augmentation procedures. Treatments were performed according to the standard protocols applied in the private practices. More than 10,000 implants were inserted in various indications and were followed up to 20.2 years from the day of implant insertion. The o...
When looking into the Kaplan-Meier implant survival curves of the augmentation procedures using the log-rank test, the highest implant survival was found for bone condensing followed by lateral augmentation, internal sinus lift, transplantation of bone blocks, bone splitting/spreading, titanium mesh, external sinus lift (one- and two-step) and finally, no augmentation. This sequence was statistica...
Results
Of the 10,158 implants, 58.2% (5916 implants) were inserted using an augmentation procedure. The minimal observation period until the last control visit or until explantation was 0 days (day of implantation); the maximum period was 20.2 years. Distribution of analysed implants according to the period of observation is shown in Table 1.

Although there are only very few cases in the literature with augmentation of bone/sinus lift, these procedures are linked to a functioning vascular recipient site with working osteoclastic resorption and osteoblastic bone formation, and this is compromised in patients with antiresorptive therapy. Due to the denudation of the bone at the recipient site the vascular situation might be e...
Discussion
Even latest guidelines and statements dealing with medication associated osteonecrosis of the jaws such as the American, Scottish, Swiss or German do not address implant therapy in these patients in detail. Due to this lack of data a systematic literature review was performed to fill this gap. Unfortunately the literature dealing with this topic is very sparse and consists mainl...
Nibbe analyzed 128 patients with IV BP or denosumab separated into 3 groups. In the first group 5 out of 60 patients with no denture had an osteonecrosis (8%), in the 2nd group 5 out of 34 patients with a fixed partial denture had an osteonecrosis 15%, and in the 3rd group 11 out of 34 patients with a removable denture had an osteonecrosis (32%). Kyrgidis determined that dentures increase the ris...
Results
Out of 606 articles 556 articles were excluded because they were either duplicates, case reports, narrative reviews, case series with less than 5 cases or were not associated with the topic at all (Table 1 and Fig. 1). Some of the articles analyzed more than one outcome and are referred to several times. Since the available literature is very inhomogeneous with a low level of evidence a...
Introduction
Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is a well-known side effect in patients receiving bisphosphonates (BP) due to e.g. osteoporosis, multiple myeloma or malignant diseases with metastases to the bone; prevalences range between 0.1% for patients with primary osteoporosis to 1% in patients with secondary osteoporosis and up to about 20% for special high risk ...
Dental implants in patients treated with antiresorptive medication – a systematic literature review
Abstract
Objective
Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is triggered by inflammatory processes. Typical trigger factors are periodontal disease, denture pressure sores, and surgical interventions such as tooth extractions. Unfortunately there is only little data on how...

This study presents new data on maxillary sinus mucosal thickening derived from a carefully defined data set; however, there were some limitations in the study. One limitation was the limited sample size. However, as discussed, our stringent case selection criteria yielded a more uniform data set for analyses. Other limitations were related to the actual measurements of the maxillary sinus. ...
Our study did not find a significant association between endodontically treated teeth and mucosal thickening. Though this finding is consistent with some previously published studies, other studies did report an association. These discrepant findings could be the result of different inclusion criteria in the study design. Since our study did not include any patients with radiographic signs o...
The current study demonstrated that sinus mucosal thickening does not correlate with implant survival. This result is consistent with a previously published report by Jungner et al. In their study, the presence of sinus thickening was not significantly associated with implant failure. Similarly, our study found a 100% implant survival rate for both patients with and without sinus mucosal thi...
Discussion
CBCT imaging has been recognized as a more sensitive imaging modality for identifying sinus thickening and pathoses in the posterior maxilla compared to panoramic radiography. This could explain why the current study identified a higher prevalence of mucosal thickening compared to earlier studies. However, compared to other similar CBCT studies, the prevalence reporte...
Results
Twenty-nine CBCT images (11 females and 18 males) were included in this study. All the implants placed in these included cases survived, representing a 100% implant survival rate. With regards to measurements of mucosal thickening, the intra-examiner reproducibility revealed an exact intra-examiner correlation of 99%, with a p value of 0.40 for a t test for independen...
In order to standardize the measurements for each sinus, each scan was carefully oriented in the axial, coronal, and sagittal plane. In the axial plane, a horizontal line from the right and left zygoma was chosen as the standard. Orienting the hard palate horizontally was the standard in the coronal plane as well as in the sagittal plane. The specific teeth that were to be replaced by implants wer...
Given these specific inclusion and exclusion criteria and the specific purpose of this study, only 29 cases qualified for inclusion from an original screen of approximately 4000 cases. An initial search of our database resulted in a larger number of cases that would theoretically qualify; however, further investigation revealed the need to exclude a great number of cases. The reasons for exclusion...
Methods
Study design
Our study hypothesis was that mucosal thickening of more than 2 mm and up to 1/3 of the volume of the sinus would not alter the predictability for SFE and dental implant placement. The primary outcome was to determine the success rate of dental implant placement in augmented maxillary sinus areas with mucosal thickening. A secondary outcome was to evaluate the effect of g...
Background
Despite the high survival rate of dental implants inserted in maxillary sinuses that have undergone sinus floor elevation (SFE) with bone grafting, complications still occur. Sinus membrane perforation is reported to be the most common complication. Postoperative maxillary sinusitis is less common (0–22%); nevertheless, it could potentially compromise the outcome of...
Dental implants and grafting success remain high despite large variations in maxillary sinus mucosal thickening
Abstract
Background
Although mucosal thickening is the most common radiographic finding observed regarding sinus pathology, the knowledge regarding its clinical significance on the outcomes of dental implants and grafting in the maxillary sinuses is still limited. We hypothesized th...
