An important finding in this study is that a majority of patients were very satisfied after iliac crest-derived alveolar bone grafting and implant therapy. Although 90% of the patients in our study had successful bone grafting, only 70.1% reported implant survival together with prosthetic rehabilitation after 1 year. These figures are lower than those reported in previous studies [2, 3, 9]. A rev...
The correlation analyses performed did not show a significant correlation between the complications at the donor site and implant loss (Table 4).
The mean OHIP-14 score (Table 5) was 8.4 ± 9.7 (range 0–56) in 44 patients of whom 35 patients scored 14 or less. Nine patients scored a total sum of 1 [1], i.e. “hardly ever” impact on any single item and “at no time” on the remaining ...
The final sample consisted of 44 patients that responded and completed the questionnaire, giving a response rate of 74.6%: 24 women and 20 men, mean age of 61.2 years ± 13.1 (range 27–82 years). The mean time from augmentation surgery until completing the questionnaire was 7.8 years ± 2.65 (range 1.9–12 years).

Health-related QoL (HRQoL) is a dynamic concept referring to an individual’s subjective assessment and perspective of current general health condition as well as functional, social, and emotional well-being [23, 24]. Most people regard oral health as important for QoL, and this is mediated through the concept of oral health-related QoL (OHRQoL) [25]. In this regard, OHRQoL is an important PROM i...
Insufficient alveolar bone volume, as a result of periodontal disease, trauma, congenital anomalies and/or resorption atrophy, often presents a clinical challenge for optimal placement of dental implants for prosthetic rehabilitation. In such cases, augmentation of alveolar bone, with either autologous bone, allogeneic, xenogeneic, or alloplastic biomaterials, is a prerequisite for placing implant...
The objective of this study was to assess patient-reported outcomes such as satisfaction and quality of life after advanced alveolar bone augmentation with anterior iliac crest grafting and implant treatment in orally compromised patients.
This cross-sectional retrospective cohort study included 59 patients (29 women and 30 men) with major functional problems, who underwent advanced alveolar augm...

In conclusion, the repositioning of the bone window after sinus floor elevation in sheep, compared with the use of a resorbable membrane, improved the closure of the antrostomy and led to a greater amount of the newly formed bone in the close-to-window zone of the grafted area. The bone window appeared partially bonded to the newly formed bone. Bridges of new bone from the edges of the antrostomy ...
In the present study, a lesser amount of bone was registered subjacent to the sinus mucosa compared with the other regions. This is in agreement with another experiment, in which a similar material was used for sinus augmentation in sheep [24]. A similar outcome was also reported in another study [27] that used DBBM xenograft for sinus augmentation in sheep. In that study, a collagen membrane was ...
In another similar experiment in sheep, the sinuses were augmented using a similar biphasic calcium phosphate (60% HA, 40% β-TCP) [24], the biomaterial used in the present study. The perforation of the sinus mucosa was performed at the test sites and a collagen membrane was placed to protect the perforation, while at control sites the elevated mucosa was left unprotected. After 12 weeks of heal...
The aim of the present study was to compare the healing of the augmented sinus in large animals, where the antrostomy was covered by a polylactic membrane or a repositioned bone plate, both secured with cyanoacrylate.
No statistically significant differences were found between test and control sites in the bone formation within the augmented space. This outcome is in agreement with a similar stud...
In the centre of the window area, at the test sites, in the analysed histological sections, the bone plate was still visible in five out of six sheep. It appeared partly remodelled and connected by the new bone formed in the sub-window area. Out of the five bone plates still present, three were bridged to the edges of the antrostomy, while in the two cases no contact was achieved in the observed s...
During surgery, one sheep showed acute sinusitis at the test site. The sinus mucosa was perforated to allow sinus drainage and surgery was completed. During the healing period, no evident clinical complications were observed.
At the histomorphometric analysis, one sinus of the control group and one of the test group (corresponding to the sinusitis case) appeared to have lost almost all biomateria...
The percentages of the new mineralised bone, soft or connective tissue, pure graft, graft interpenetrated by bone, and remnants of cyanoacrylate were evaluated. The total tissue percentages in the elevated space that included submucosa, middle, base, and sub-window regions were also calculated.

After 4 months, the animals were anaesthetised and then euthanised with an overdose of pentobarbital sodium and subsequently perfused with 10% formalin. The maxilla was retrieved en bloc, trimmed, and immersed in formalin solution.

Through an extra-oral approach, an oblique incision was made bilaterally along the sagittal axis between the facial tuberosity and the inferior orbital rim. The skin and periosteum were elevated separately, and the bony facial sinus wall was exposed on both sides of the maxilla (Fig. 1a).

To prevent the movement of the bony plate and to gain adequate stability, cyanoacrylate has been suggested to glue the plate to the bony edges of the antrostomy [17]. Cyanoacrylates (as methyl 2-cyanoacrylate or ethyl 2-cyanoacrylate) are widely used in surgery and have shown good compatibility [18] and biomechanical strength for fixation of grafts [19]. In an experiment in rabbits [17], the antro...
Sinus floor elevation is a commonly used technique to increase bone volume in the posterior maxilla prior to implant placement. This procedure was first developed by Tatum in 1977 [1], modified by Boyne and James in 1980 [2], and further modified over time. In this well-described technique, a bony window is created on the lateral wall of the sinus with a round burr, and the membrane elevated. Diff...
The objective of this study was to compare the healing of the augmented sinus at which the antrostomy was covered with a membrane or the repositioned bone plate.

Most people regard oral health as important for QoL, and this is mediated through the concept of oral health-related QoL (OHRQoL) [25]. In this regard, OHRQoL is an important PROM i...
Insufficient alveolar bone volume, as a result of periodontal disease, trauma, congenital anomalies and/or resorption atrophy, often presents a clinical challenge for optimal placement of dental implants for prosthetic rehabilitation. In such cases, augmentation of alveolar bone, with either autologous bone, allogeneic, xenogeneic, or alloplastic biomaterials, is a prerequisite for placing implant...
The objective of this study was to assess patient-reported outcomes such as satisfaction and quality of life after advanced alveolar bone augmentation with anterior iliac crest grafting and implant treatment in orally compromised patients.
This cross-sectional retrospective cohort study included 59 patients (29 women and 30 men) with major functional problems, who underwent advanced alveolar augm...

In conclusion, the repositioning of the bone window after sinus floor elevation in sheep, compared with the use of a resorbable membrane, improved the closure of the antrostomy and led to a greater amount of the newly formed bone in the close-to-window zone of the grafted area. The bone window appeared partially bonded to the newly formed bone. Bridges of new bone from the edges of the antrostomy ...
In the present study, a lesser amount of bone was registered subjacent to the sinus mucosa compared with the other regions. This is in agreement with another experiment, in which a similar material was used for sinus augmentation in sheep [24]. A similar outcome was also reported in another study [27] that used DBBM xenograft for sinus augmentation in sheep. In that study, a collagen membrane was ...
In another similar experiment in sheep, the sinuses were augmented using a similar biphasic calcium phosphate (60% HA, 40% β-TCP) [24], the biomaterial used in the present study. The perforation of the sinus mucosa was performed at the test sites and a collagen membrane was placed to protect the perforation, while at control sites the elevated mucosa was left unprotected. After 12 weeks of heal...
The aim of the present study was to compare the healing of the augmented sinus in large animals, where the antrostomy was covered by a polylactic membrane or a repositioned bone plate, both secured with cyanoacrylate.
No statistically significant differences were found between test and control sites in the bone formation within the augmented space. This outcome is in agreement with a similar stud...
In the centre of the window area, at the test sites, in the analysed histological sections, the bone plate was still visible in five out of six sheep. It appeared partly remodelled and connected by the new bone formed in the sub-window area. Out of the five bone plates still present, three were bridged to the edges of the antrostomy, while in the two cases no contact was achieved in the observed s...
During surgery, one sheep showed acute sinusitis at the test site. The sinus mucosa was perforated to allow sinus drainage and surgery was completed. During the healing period, no evident clinical complications were observed.
At the histomorphometric analysis, one sinus of the control group and one of the test group (corresponding to the sinusitis case) appeared to have lost almost all biomateria...
The percentages of the new mineralised bone, soft or connective tissue, pure graft, graft interpenetrated by bone, and remnants of cyanoacrylate were evaluated. The total tissue percentages in the elevated space that included submucosa, middle, base, and sub-window regions were also calculated.
Mean values and standard deviations (SDs) as well as the 25th, 50th (median), and 75th percentiles were...
After 4 months, the animals were anaesthetised and then euthanised with an overdose of pentobarbital sodium and subsequently perfused with 10% formalin. The maxilla was retrieved en bloc, trimmed, and immersed in formalin solution.

Through an extra-oral approach, an oblique incision was made bilaterally along the sagittal axis between the facial tuberosity and the inferior orbital rim. The skin and periosteum were elevated separately, and the bony facial sinus wall was exposed on both sides of the maxilla (Fig. 1a).

To prevent the movement of the bony plate and to gain adequate stability, cyanoacrylate has been suggested to glue the plate to the bony edges of the antrostomy [17]. Cyanoacrylates (as methyl 2-cyanoacrylate or ethyl 2-cyanoacrylate) are widely used in surgery and have shown good compatibility [18] and biomechanical strength for fixation of grafts [19]. In an experiment in rabbits [17], the antro...
Sinus floor elevation is a commonly used technique to increase bone volume in the posterior maxilla prior to implant placement. This procedure was first developed by Tatum in 1977 [1], modified by Boyne and James in 1980 [2], and further modified over time. In this well-described technique, a bony window is created on the lateral wall of the sinus with a round burr, and the membrane elevated. Diff...
The objective of this study was to compare the healing of the augmented sinus at which the antrostomy was covered with a membrane or the repositioned bone plate.
Eight sheep underwent bilateral maxillary sinus floor augmentation. The control site was covered with a resorbable membrane, while at the experimental site the bone plate was repositioned, and both were secured with cyanoacrylate. Animal...

To overcome the shortcomings of this case reports, prospective, multicenter, and controlled studies must follow to affirm a potential relationship between vitamin D deficiency, osteoimmunology, and the early failure of dental implants. Currently, a general recommendation for a standardized vitamin D screening in dental implantology cannot be stated due to lack of evidence.
Nevertheless, the vitamin D deficiency prevalence in the European population indicates that a vitamin D deficiency is probably not a sole causative factor for early implant failure; otherwise, the early implant failure rate would be significantly higher. However, a synergistic effect with other factors is conceivable. Some authors stated that implant osseointegration is not simply a wound healing ...
Local and systemic factors can affect the survival rate of dental implants [30–33]. The causes of early implant failure are not fully clarified and an association between vitamin D and dental implant osseointegration has not been investigated properly [8, 13–16]. Some recent animal studies in rodents demonstrated a relationship between vitamin D supplementation and an increased bone to implant...
In this 51-year-old male patient, no grafting procedure was performed as vertical and horizontal alveolar ridge dimension was adequate for implant placement. The implant placement in regions 36 and 37 was performed as guided surgery (Fig. 2a, Table 1). The implant placement was uneventful and the bone appeared clinically healthy. A cortical bone profiling was performed during implant placement. ...
The medical history of this 48-year-old male patient showed a high blood pressure; otherwise, the patient was healthy. A successfully completed periodontal therapy was done before implant therapy. The patient demonstrated stable marginal bone levels. Autologous retromolar bone grafting using local anesthesia was performed in the left mandible (see Fig. 1a). This patient received a postoperative o...

Long-term stable osseointegrated implants are the primary goal in dental implantology. Although dental implants have proven clinical reliable in the long term, the failure of implants at a very early stage of osseointegration has been described [1, 2]. The pursuit to identify the mechanisms leading to early implant failure is ongoing to date and include the following: tobacco usage, diabetes, wear...
An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants from different...

We described in the present case a vertical lack of the bone from the alveolar ridge to the opposing teeth, the short distance from the reabsorbed ridge to the floor of the maxillary sinus, and the presence of septa and a thickened sinus membrane within the maxillary sinus. A sandwich bone graft was successfully applied and followed up in the long term. The resulting gains in ridge height and incr...
In this case, the alveolar ridge was Seibert class II, and septa and a thickened sinus membrane were evident within the maxillary sinus. Sinus floor elevation was limited because of the condition of the floor morphology, the presence of septa, and the thickness of sinus floor membrane [22, 23]. Considering these issues, we selected the interpositional bone graft technique using autologous bone in ...

Six months after surgery, radiological examinations were carried out and the patient underwent implant placement (Fig. 4). The postoperative bone height had increased to 10.1 mm at position 26 and 12.9 mm at position 27 compared with the preoperative heights of 6.1 and 7.5 mm, respectively.

In the literature, the technique of segmental osteotomy accompanied by interpositional grafting has been reported as a practical and predictable procedure with a low incidence of complications and a high probability of success [15,16,17,18,19]. This approach leaves the soft tissue on the oral side of the midcrestal incision attached to the crestal bone segment. Various studies have shown that alve...
Osseointegrated implants for the replacement of missing teeth have recently become a routine treatment option [1, 2]. However, any tooth loss may be followed by extensive resorption of the alveolar ridge, which usually makes implant placement difficult or impossible because of the lack of bone volume. There are a variety of defect situations with increasing complexity, ranging from fenestrations, ...
The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons. This report describes the outcome of treatment after alveolar ridge augmentation in the atrophic posterior maxillary region via segmental ...

In the literature, the technique of segmental osteotomy accompanied by interpositional grafting has been reported as a practical and predictable procedure with a low incidence of complications and a high probability of success [15,16,17,18,19]. This approach leaves the soft tissue on the oral side of the midcrestal incision attached to the crestal bone segment. Various studies have shown that alve...
Osseointegrated implants for the replacement of missing teeth have recently become a routine treatment option [1, 2]. However, any tooth loss may be followed by extensive resorption of the alveolar ridge, which usually makes implant placement difficult or impossible because of the lack of bone volume. There are a variety of defect situations with increasing complexity, ranging from fenestrations, ...
The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons. This report describes the outcome of treatment after alveolar ridge augmentation in the atrophic posterior maxillary region via segmental ...

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.

The results of this clinical study support the use of a biphasic in situ hardening alloplastic bone graft substitute for ridge preservation in intact post-extraction sites without the use of a dental membrane. Therefore, grafting of sockets without primary wound closure or using dental membranes or a soft tissue punch can be an effective minimally invasive method of preserving the contour and arch...
Likewise, the reported amount of residual grafting material in the defect site was similar. In average, only 26.2 ± 9.4% of the defect was occupied with residual graft material in this study which is well in line with 26.6 ± 5.2% reported for BCP but below the 37.7 ± 8.5% reported for xenograft [14].
All 15 implants could be placed without the need for additional bone augmentation....
As previously reported, secondary intention soft tissue healing of grafted post-extraction sites can be well achieved when using an in situ hardening and in situ stabilizing bone graft substitutes without the need of a dental membrane [18, 20]. Findings of the present report corroborate these results. The authors found that all sites healed uneventfully with coverage of soft tissue and no local co...
Ridge preservation following dental extractions is fundamental, preserving the ridge profile for subsequent implant placement and providing a sustained function and esthetics. This clinical trial reports on the successful application of an in situ hardening biphasic alloplastic bone graft substitute for ridge preservation and subsequent implant placement in 15 healthy patients. A routine but minim...
Cone beam computer tomography (CBCT) was performed before tooth extraction and at the time point of implant placement. Mean ridge width reduction before tooth extraction to implant placement was calculated to effect in 0.79 ± 0.73 mm horizontal bone loss (Table 2). Primary implant stability was achieved in all 15 cases, showed in average high ISQ levels 70.3 ± 9.7 (buccal/palatal), and...
Fifteen patients (4 females and 11 males) with a mean age of 51.3 + 14.8 years (range: 27 to 75 years) participated in this randomized clinical trial. The site specific areas and teeth numbers for the study are shown in Table 1.
In all cases, the postoperative healing was uneventful. Clinically, the soft tissue healing pattern observed was very similar in all cases. The soft tissue on all ...
Bone biopsies were harvested using a trephine bur at the site of implant placement. The trephine burs including the bone biopsies were fixed in 4% formalin for 5–7 days, rinsed in water, and dehydrated in serial steps of ethanol (70, 80, 90, and 100%), remaining for 1 day in each concentration. Specimens were then infiltrated, embedded, and polymerized in resin (Technovit 9100, Heraeus Kulzer,...
Antibiotic therapy consisting of 1 g amoxicillin every 12 h for 4 days and mouth rinsing with 0.2% chlorhexidine every 8 h for 10 days were prescribed. The suture was removed 1 week postoperatively. After 3 to 8 months (average 5.2 ± 2 months), the sites (Fig. 2a) were reentered for implant placement. A site-specific full thickness mucoperiosteal flap was elevated to expose the regen...
This study was approved by the Yenepoya University Ethics committee, Mangalore, India (Approval Number YOEC83/8/3/2014).

To our knowledge, this is the first systematic clinical, radiographic, and histological evaluation that assesses bone formation and ridge width preservation after socket grafting using an in situ hardening biphasic bone graft substitute in healthy patients.
Following tooth extraction, the alveolar ridge will decrease in volume and change its morphology [1, 2]. These changes are clinically significant [3] and can complicate the placement of a conventional bridge or an implant-supported crown. Post-extraction maintenance of the alveolar ridge following the principles of ridge preservation using bone graft substitutes minimizes ridge resorption and, thu...
Post-Extraction ridge preservation using bone graft substitutes is a conservative technique to maintain the width of the alveolar ridge. The objective of the present study was to evaluate an in situ hardening biphasic (HA/β-TCP) bone graft substitutes for ridge preservation without primary wound closure or a dental membrane.
A total of 15 patients reported for tooth extraction were enrolled in t...

We described in the present case a vertical lack of the bone from the alveolar ridge to the opposing teeth, the short distance from the reabsorbed ridge to the floor of the maxillary sinus, and the presence of septa and a thickened sinus membrane within the maxillary sinus. A sandwich bone graft was successfully applied and followed up in the long term. The resulting gains in ridge height and incr...
In this case, the alveolar ridge was Seibert class II, and septa and a thickened sinus membrane were evident within the maxillary sinus. Sinus floor elevation was limited because of the condition of the floor morphology, the presence of septa, and the thickness of sinus floor membrane [22, 23]. Considering these issues, we selected the interpositional bone graft technique using autologous bone in ...
This paper reports on a segmental osteotomy procedure with an interpositional graft in the posterior maxillary region with 9 years of follow-up.
The techniques used to overcome a lack of alveolar bone height rely on the placement supplemented by various vertical guided bone regeneration (GBR) procedures [4, 5] and the use of alveolar distraction osteogenesis [6], titanium mesh [7], or onlay bone...
Six months after surgery, radiological examinations were carried out and the patient underwent implant placement (Fig. 4). The postoperative bone height had increased to 10.1 mm at position 26 and 12.9 mm at position 27 compared with the preoperative heights of 6.1 and 7.5 mm, respectively. Postoperative clearance was reduced by 11 mm compared with the preoperative clearance. Careful separati...
A 67-year-old male patient sought implant rehabilitation for the purposes of restoration of occlusal support and assistance with chewing difficulties. Clinical and radiological examinations revealed that teeth were absent 26–27. The clearance from the alveolar ridge to the opposing teeth was 20 mm (Fig. 1). A CT scan showed that the distance from the reabsorbed ridge to the floor of the maxill...
In the literature, the technique of segmental osteotomy accompanied by interpositional grafting has been reported as a practical and predictable procedure with a low incidence of complications and a high probability of success [15,16,17,18,19]. This approach leaves the soft tissue on the oral side of the midcrestal incision attached to the crestal bone segment. Various studies have shown that alve...
Osseointegrated implants for the replacement of missing teeth have recently become a routine treatment option [1, 2]. However, any tooth loss may be followed by extensive resorption of the alveolar ridge, which usually makes implant placement difficult or impossible because of the lack of bone volume. There are a variety of defect situations with increasing complexity, ranging from fenestrations, ...
The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons.

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.
A consecutive retrospective study was conducted on all patients who were treated at the military outpatient clinic of the Department of Oral and Plastic Maxillofacial Surgery at the military hospital in Ulm (Germany) in the ...

The results of this clinical study support the use of a biphasic in situ hardening alloplastic bone graft substitute for ridge preservation in intact post-extraction sites without the use of a dental membrane. Therefore, grafting of sockets without primary wound closure or using dental membranes or a soft tissue punch can be an effective minimally invasive method of preserving the contour and arch...
Likewise, the reported amount of residual grafting material in the defect site was similar. In average, only 26.2 ± 9.4% of the defect was occupied with residual graft material in this study which is well in line with 26.6 ± 5.2% reported for BCP but below the 37.7 ± 8.5% reported for xenograft [14].
All 15 implants could be placed without the need for additional bone augmentation....
As previously reported, secondary intention soft tissue healing of grafted post-extraction sites can be well achieved when using an in situ hardening and in situ stabilizing bone graft substitutes without the need of a dental membrane [18, 20]. Findings of the present report corroborate these results. The authors found that all sites healed uneventfully with coverage of soft tissue and no local co...
Ridge preservation following dental extractions is fundamental, preserving the ridge profile for subsequent implant placement and providing a sustained function and esthetics. This clinical trial reports on the successful application of an in situ hardening biphasic alloplastic bone graft substitute for ridge preservation and subsequent implant placement in 15 healthy patients. A routine but minim...
Cone beam computer tomography (CBCT) was performed before tooth extraction and at the time point of implant placement. Mean ridge width reduction before tooth extraction to implant placement was calculated to effect in 0.79 ± 0.73 mm horizontal bone loss (Table 2). Primary implant stability was achieved in all 15 cases, showed in average high ISQ levels 70.3 ± 9.7 (buccal/palatal), and...
Fifteen patients (4 females and 11 males) with a mean age of 51.3 + 14.8 years (range: 27 to 75 years) participated in this randomized clinical trial. The site specific areas and teeth numbers for the study are shown in Table 1.
In all cases, the postoperative healing was uneventful. Clinically, the soft tissue healing pattern observed was very similar in all cases. The soft tissue on all ...
Bone biopsies were harvested using a trephine bur at the site of implant placement. The trephine burs including the bone biopsies were fixed in 4% formalin for 5–7 days, rinsed in water, and dehydrated in serial steps of ethanol (70, 80, 90, and 100%), remaining for 1 day in each concentration. Specimens were then infiltrated, embedded, and polymerized in resin (Technovit 9100, Heraeus Kulzer,...
Antibiotic therapy consisting of 1 g amoxicillin every 12 h for 4 days and mouth rinsing with 0.2% chlorhexidine every 8 h for 10 days were prescribed. The suture was removed 1 week postoperatively. After 3 to 8 months (average 5.2 ± 2 months), the sites (Fig. 2a) were reentered for implant placement. A site-specific full thickness mucoperiosteal flap was elevated to expose the regen...
This study was approved by the Yenepoya University Ethics committee, Mangalore, India (Approval Number YOEC83/8/3/2014). Fifteen patients who required extraction of a maxillary or mandibular tooth and subsequent single-tooth implant placement and who met the inclusion and exclusion criteria were included in this prospective single-arm clinical study. The patients (4 females and 11 males) had a mea...
To our knowledge, this is the first systematic clinical, radiographic, and histological evaluation that assesses bone formation and ridge width preservation after socket grafting using an in situ hardening biphasic bone graft substitute in healthy patients.
Following tooth extraction, the alveolar ridge will decrease in volume and change its morphology [1, 2]. These changes are clinically significant [3] and can complicate the placement of a conventional bridge or an implant-supported crown. Post-extraction maintenance of the alveolar ridge following the principles of ridge preservation using bone graft substitutes minimizes ridge resorption and, thu...
Post-Extraction ridge preservation using bone graft substitutes is a conservative technique to maintain the width of the alveolar ridge. The objective of the present study was to evaluate an in situ hardening biphasic (HA/β-TCP) bone graft substitutes for ridge preservation without primary wound closure or a dental membrane.
A total of 15 patients reported for tooth extraction were enrolled in t...

Within the limits of this systematic review, the chairside method to harvest BMAC is a viable option for maxillary sinus augmentation for implant site development. The implant survival of the BMAC group was similar to the laboratory FICOLL concentration of BMAC group, without the additional cost and time of laboratory cell isolation techniques. Single or double centrifugation of BMAC does not appe...
In addition, the parameters to evaluate new bone formation were variable. New bone formation and percentage of vital bone are different methods to measure bone formation, and the data from different methods could not be combined or analyzed together. Furthermore, the BMAC evaluated in test groups were prepared differently and were harvested from different sources (tibia or iliac). The control grou...
Although the variations of the materials and methods for BMAC preparation were discussed, this review was not aimed to compare materials and methods for BMAC preparation, but rather the end clinical result for new bone formation and implant survival. Although implant survival and new bone formation were not the only parameters to consider when evaluating sinus augmentation, these parameters were t...
It appears that BMAC offers no statistically significant advantage for regeneration of bone in the maxillary sinus for site preparation of dental implants. BMAC + bovine bone graft results in similar regeneration outcome measures histologically as alveolar bone alone at 3–4 months. Measured histomorphometrically MSCs treated by FICOLL–Hypaque centrifugation to consolidate osteogenic and osteo...
Pasquali et al. [7], in eight patients compared BMAC + bovine bone graft (test group) with bovine bone graft alone (control group). New bone (55.15%) was reported in the test group compared with new bone (27.3%) in the control group based on histomorphometric analyses. This reported observation indicating statistically more new bone regeneration in the BMAC + bovine bone graft group compared with ...
Sauerbier et al. [14] further compared BMAC + bovine bone grafts (test group) with alveolar bone, autologous + bovine bone grafts (control group) for maxillary sinus site preparation. New bone (31.3%) for the test group compared with new bone (19.3%) for the control group statistically indicated equivalence in histomorphometric outcome. Histologic images showing impressive new bone formation were ...
Mesenchymal stem cells (MSCs) in BMAC have the potential to renew, experience clonal expansion, and differentiate into musculoskeletal tissues [16]. MSCs are also known to have an immunoregulatory role and may enhance the normal healing response and angiogenesis [10]. BMAC has been used in bone, cartilage, and tendon injuries with encouraging results [16]. BMAC is a minimally invasive procedure, a...

Maxillary sinus augmentation is indicated when there is an inadequate vertical alveolar bone height to effectively support surgically placed dental implants. The sinus elevation procedure requires grafting bone material onto the sinus floor to regenerate sufficient vertical alveolar bone height [1, 2]. The ideal bone grafting material should be biocompatible, possess no risk of disease transmissio...
Maxillary sinus pneumatization following dental tooth extractions and maxillary alveolar bone resorption frequently leaves inadequate bone levels for implant placement. The objectives of this systematic review are to evaluate the effects of bone marrow aspirate concentrates (BMACs) used in maxillary sinus augmentation for implant site development.
A systematic search was conducted using PubMed, E...

The current review showed that the exposure of dental implants in the sinus cavity without the augmentation procedure or graft materials shows a high survival rate of 95.6%, without statistically significant differences according to the level of penetration (lower or higher to 4 mm). Changes in maxillary sinuses in relation to protruding implants within the sinus cavity do not statically affect ...
Consequently, it seems that maxillary sinus changes in relation to protruded implants inside the sinus cavity and does not statically affect to implant survival rate neither to clinical nor radiographic complications.
Several limitations could be described for the present review. Firstly, there is a lack of a control group in the included studies, to compare outcomes and complications, with impla...
Pneumatization of the maxillary sinus and resorption of the residual alveolar ridge following tooth extraction can compromise the dental implant placement. Similarly, extension of the dental implants inside the maxillary sinus cavity is not rare. Some studies have observed some differences in relation to the depth of the implant extension inside the sinus cavity. When the implants penetrate inside...
Seven studies [27,28,29,30,31,32,33] provide information on clinical complications with a global sample of 232 patients.

Intrusion of dental implants into the maxillary sinus perforating through the Schneiderian membrane is considered a cause of undesirable complications [24, 25]. However, this phenomenon has never been properly evaluated and systematically studied. For this reason, the aim of this systematic review was to assess the implant survival and complication rates of implants intruding into the sinus cavity...
The edentulous posterior maxillary region often presents with unique challenging conditions in implant dentistry [1]. Limited bone height secondary to pneumatization of the maxillary sinus and the resorption of the alveolar ridge preclude in many instances the installation of dental implants. To compensate for the lack of bone height, several treatment options have been proposed.

The overall survival rate of the implants into the sinus cavity was 95.6%, without statistical differences according to the level of penetration. The clinical and radiological complications were 3.4% and 14.8% respectively. The most frequent clinical complication was the epistaxis, and the radiological complication was thickening of the Schneiderian membrane, without reaching statistical significa...

Conclusion
Within the limitations of the current review, it can be concluded that implant survival in autogenous bone grafts in H&N oncology patients appears to be promising with implant survival being reported at over 80% in 16 of the 20 studies included with 11 of these reporting implant survival of over 90% in follow-up ranging from 3 months [28] to 15 years [5]. However, there i...
A clear deficiency of many of the studies was the imprecise and inconsistent definitions of implant survival or implant success, as detailed in Table 1. In addition, in a number of studies, the terminology ‘implant success’ and ‘implant survival’ were used interchangeably within the narrative making comparison of the studies challenging and rendering statistical analysis of the surv...
The implant placement protocol with regard to primary (immediate) or secondary (delayed) implant placement was also reviewed, and there is limited evidence from Fenlon et al. that implant failure is significantly worse in immediately placed implants in comparison with a delayed approach in free vascularized grafts.
Implant success was shown to be lower than implant survival and was related ...
Discussion
Summary of evidence
Dental implants are now perceived to be a vital part of the clinician’s armamentarium in the provision of oral and dental rehabilitation for patients with acquired deformity following management of their H&N cancer, and therefore, this systematic review is relevant to clinicians and stakeholders involved in the treatment and management of H&N cancer patient...
Six of these studies (Schultes et al., Wang et al., Zou et al., Chiapasco et al., Chiapasco et al., Wu et al.) reported some of this lack of success to the peri-implant soft tissue which was most frequently the soft tissue component of a combined bone and soft tissue free flap (most commonly the external skin).
Complications
A variety of implant-based complications were documented. Complicatio...
Implant survival and Peri-implant soft tissue
Only one study (Linsen et al. ) reported on the effect of the peri-implant soft tissue and implant survival of implants placed into autogenous bone grafts. Linsen et al. reported a higher implant failure of implants placed into bone and soft tissue grafts in comparison to implants placed into a bone grafts with residual soft tissues. This difference...
However, in two studies (Teoh et al., Burgess et al.), no statistical significance was found despite higher implant failure.
Primary and secondary implant placement and implant survival
Six studies clearly reported the use of both primary and secondary implant placement within their study (Fenlon et al., Ch’ng et al., Zou et al., Burgess et al., Watzinger et al., Wu et al.); however, only on...
Two studies (Fenlon et al., Burgess et al. ) reported no significant effect on implant survival in varying graft donor sites; however, three studies (Hessling et al., Shaw et al., Chiapasco et al.) reported varying implant survival rates within different autogenous bone grafts but only one study (Hessling et al.) reported that implant loss was significant with this being for implants placed into...
Autogenous bone graft type and implant survival
Seventeen studies reported on the specific bone graft type (non-vascularised or vascularised) into which the implants were placed. In the remaining three studies (Buddula et al., Fierz et al., Yerit et al.), this distinction was not possible.
Of these 17 studies, 8 studies reported on implant survival in non-vascularised bone grafts and 14 studie...
The surgical and loading implant protocols were reported in 17 studies with no description given in 3 studies (Barrowman et al., Fierz et al., Hessling et al.). The implant placement protocols were diverse with variables including the use of surgical templates/guides, primary and/or secondary implant placement following autogenous bone grafting, and immediate and/or delayed implant loading; howe...
These 20 studies were published over a range of 21 years (1996 to 2017) and provide cumulative data on 1905 implants placed into autogenous bone grafts in H&N cancer patients with both benign and malignant tumours being reported. The exact patient number for this intervention within some of the studies was unclear as a result of the studies reporting on implant rather than patient number or ther...

Introduction
Rationale
The use of implants to retain prostheses as part of oral and dental rehabilitation of head and neck (H&N) cancer patients is becoming an increasingly common treatment approach. A number of benefits advocating implant anchorage over conventionally secured prostheses have been proposed but importantly include a significant improvement in the reported quality of life (QoL) of...

However, a synergistic effect with other factors is conceivable. Some authors stated that implant osseointegration is not simply a wound healing phenomenon but rather complex foreign body reaction with activation of the immune system. Titanium and metal particle release is discussed as cause for implant failure as well as implant dentistry. It is assumed that metal particles influence the ma...
However, a present human study cannot confirm an effect due to vitamin D supplementation on bone formation or graft resorption after maxillary sinus augmentation. Satue et al. found a positive influence of 7-dehydrocholesterol (7-DHC), the precursor of vitamin D, coated implants on osteoblast differentiation in vitro. But whether vitamin D-coated dental implants have an effect of osseo...
Discussion
This article demonstrated that implant placement was successful after vitamin D supplementation in patients with vitamin D deficiency and early failed implants. None of the patients showed systemic disease or did take regular medication, alcohol, nicotine, or drugs. The patients were not immunosuppressed, irradiated, or received chemotherapy. All implants were inserted with the s...
After vitamin D supplementation and a healing period of 6 months, a third surgical intervention was planned and one implant (Conelog ScrewLine) was inserted in region 36 (see Table 1 and Fig. 1d). During implant placement, the former explantation site appeared clinically fully re-ossified. The patient received an intraoperative intravenous single-dose antibiotic therapy with Isocillin 1.2 mega. At...

Background
Long-term stable osseointegrated implants are the primary goal in dental implantology. Although dental implants have proven clinical reliable in the long term, the failure of implants at a very early stage of osseointegration has been described. The pursuit to identify the mechanisms leading to early implant failure is ongoing to date and include the following: tobacco usage, diabete...
Abstract
An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants fr...
