In conclusion, dental implants protruding into the nasal cavity can cause alterations to the airflow. Dental implants partially residing in the nasal cavity can be minimal invasively treated by sectioning the apical part of the implant using a transnasal approach.
No complications were apparent during the surgical procedure. Postoperative clinical and radiological examinations demonstrated an intact nasal mucosa and an adequate resection of the dental implant to the level of the nasal floor (Fig. 3). The patient had an uneventful recovery and at 2-, 6-, and 12-month follow-up, she reported having no altered nasal airflow.

Endosseous dental implants are commonly used to rehabilitate fully or partially edentulous patients [1]. The insertion of such implants can in some cases cause complications, especially in the edentulous atrophic maxilla [2–4]. In this paper, an unusual complication of altered nasal airflow after the placement of an endosseous dental implant in the maxilla is presented. Subsequent treatment of t...
Dental implants have been in routine clinical use for over three decades and are a predictable treatment modality. However, as with all other aspects of dentistry, complications occur. A 50-year-old female patient with complaints of a long ongoing unpleasant altered nasal airflow presented herself at the VU University Medical Center Amsterdam. Visual inspection of the right nasal cavity revealed t...

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 ...

All patients underwent maxillary sinus floor augmentation at the same time as imp...
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).

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...

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.

Depending on the observers’ clinical and radiological experience, PAN alone may not be sufficient for evaluation of pathologies of the maxillary sinus. On the contrary, significant benefits of sFOV-CBCT for diagnosing symptomatic maxillary sinus pathologies were reported. Having sFOV-CBCT seems to have added additional information and confidence in comparison to PAN alone. Nonetheless, also with...
The influence of clinical experience of evaluation of PAN [34] as well as the clinical experience and routine analysis of 3D radiographs (as assumed for maxillofacial surgeons when compared to those for general practitioners) strongly influence the diagnostic value of additional three-dimensional imaging. The number of incidental findings in CBCT in addition to those seen in PAN was not of major d...
In dentistry, PAN is a widely available, useful, and important diagnostic tool for diagnosis and general preoperative planning [32] with less radiation exposure then CBCT [21]. While most dentists have used it routinely successful for years and gained significant experience in doing so [33], there are certain limitations in dependence of the region to be examined [10]. The high number of “not vi...
This study focused on three different aspects in our analysis—PAN, PAN and CBCT, as well as the influence of the different clinical and radiological experience (examples in Figs. 1 and 2).
Panoramic radiography (PAN)
When assessing PAN, the ratings were significantly lower at “good visible and can be evaluated” (9.9%) compared to “visible but cannot be evaluated” (39.5%; p
The first question for PAN addressed the imaging quality in the clinical relevant area of interest (clinical data were given). Three answers were possible: 1 = good visibility and can be evaluated, 2 = visible but cannot be evaluated, and 3 = not visible. The second question asked for an additional need for CBCT scans. Three answers were possible: 1 = required, 2 = reasonable, and 3 = not required...
In an experimental diagnostic comparison, radiographic images of 15 female and 13 male patients were assessed. Patients’ radiographs were selected from the Department of Oral, Maxillofacial and Facial Plastic Surgery of the University Medical Centre of Mainz and Rostock, Germany. All patients have had referrals to the hospitals with symptomatic maxillary sinus pathologies and received PAN (Ortho...
In order to justify CBCT use for clinical examination and diagnosis of the maxillary sinus, the aim of this study was to compare the subjective quality rating of PAN and PAN together with a small field of view (sFOV) CBCT to evaluate symptomatic maxillary sinus by clinicians with different training and clinical experience.
Non-symptomatic abnormalities of the maxillary sinus such as mucosal thickening, retention cysts, and opacification are reported to occur in up to 74% of all cases [1–6]. For diagnosis of symptomatic pathologies of the maxillary sinus like retention cysts, polyps, and tumors, panoramic radiographies (PAN) are commonly used and widely available. In PAN, not every area of interest is accurately de...
A comparison of panoramic radiography (PAN) alone and PAN together with small field of view cone beam computed tomography (sFOV-CBCT) for diagnosis of symptomatic pathologies of the maxillary sinus was carried out by clinicians of different experience.
Corresponding radiographic images (PAN/sFOV-CBCT) of 28 patients with symptomatic maxillary sinus pathologies were chosen and analyzed by two gene...

The present study showed that maxillary sinus floor augmentation with BC resulted in adequate amounts of new bone formation allowing successful implant installation, while adding EMD did not have a significant effect.
Nevertheless, the amount of bone generated with BC or BC + EMD herein was adequate to support successful implant placement and osseointegration of implants. In fact, more or less similar amounts of bone formation have been reported in studies evaluating human sinus biopsies after grafting with a variety of biomaterials (bone formation ranging approximately from 30 to 50%) [19]. On the other ha...
The present study compared the histological and histomorphometrical outcome of healing after maxillary sinus floor augmentation with BC with or without EMD, based on human biopsies. The results showed that addition of EMD did not enhance the outcome of healing, neither in terms of quality nor quantity of new bone. Nevertheless, the amount of bone generated after maxillary sinus floor augmentation ...
All ten patients showed uneventful healing after the sinus floor augmentation procedure as well as after dental implant placement, with no overt postoperative inflammation or infection. Consistently, in all ten patients, no significant jiggling of the drill was noticed during biopsy harvesting, while subjective drilling resistance during implant placement was similar in both groups and all implant...

The aim of the present study was to compare histomorphometrically the outcome of maxillary sinus floor augmentation with β-TCP/HA with or without enamel matrix proteins (BC + EMD and EMD, respectively) in humans.
Reconstruction of the edentulous and severely atrophied posterior maxilla is often performed by means of maxillary sinus floor augmentation in combination with dental implants [1, 2]. Various bone graft materials are typically used for enhancing bone formation within the sinus cavity; autogenous bone (AB) is considered as the gold standard due to its osteogenic, osteoinductive, and osteoconductive...
It is still unclear whether enamel matrix proteins (EMD) as adjunct to bone grafting enhance bone healing. This study compared histomorphometrically maxillary sinus floor augmentation (MSFA) with β-TCP/HA in combination with or without EMD in humans.

An amendment to this paper has been published and can be accessed via the original article.
Within the limitation of this study and that of an ex vivo study, we can accept our hypotheses that the balloon is better than the BAOSFE in elevating the membrane mucosa and the CAS kit is better than the BAOSFE in preparing the osteotomy and breaking the sinus floor for elevation heights of 7 mm. Further, in vivo studies need to be taken to prove these findings.
The BAOSFE technique caused perforations in the membrane in 7 out of 12 cases with a percentage of 58.4. This result is consistent with many previous studies which state that this technique has a high rate of perforations when the RBH is less than 5 mm [2, 7, 26]. Also, all the perforations happened during the elevation process; however, this percentage is different than that reported by Steltzle...
Using a reamer instead of the osteotomes for breaking the sinus floor has the advantage of creating a thin bone shell that prevents direct contact between the drill and the Schneiderian membrane [24]. Moreover, using a reamer has been shown to cause less discomfort and nausea when compared to the osteotome technique as a result of the constant tapping of the osteotomes [25]. As a result, the CAS k...
Although the lateral sinus floor elevation is a proven clinically successful technique [14], the indirect SFE approach is favorable among clinicians because it does not require a second surgery site and hence cause less trauma and discomfort for the patient [14,15,16]. However, this method has its drawbacks, such as a higher risk of membrane perforation, a decreased space for using surgical instru...
For the entire sample, the mean perforation length was (0.711 mm, SD = 1.4) and the mean time required to perform the procedure was (5.65 min, SD = 2.26), and out of the entire sample (N = 36), perforations happened in nine cases for a percentage of 25%.
Chi-square test showed a significant association between method used and the occurrence of perforation (chi-square statistic = 8.585, ...
This approach starts like BAOSFE. The osteotomy is enlarged to 5.0 mm before the balloon (Zimmer Sinus Lift Balloon, Zimmer Dental Inc., California, USA) is inserted (Fig. 3). The sinus floor was broken with the 5 mm osteotome after the addition of bone. The sleeve of the balloon was inserted 1 mm beyond the sinus floor. The saline was injected slowly from the syringe into the balloon, so the ...
To achieve our purposes, an experimental ex vivo study was carried. This research project was approved by the University of Damascus Local Research Ethics Committee (UDDS-3045PG.) and was funded by the Damascus University Postgraduate Research Budget (97687027834DEN). The sinus floor elevations were done on 18 bisected heads of lambs aged between 6 and 12 months that were slaughtered in a maximum...
Therefore, the two working hypotheses of our study were “the CAS-Kit is safer than BAOSFE in breaking the sinus floor and the balloon is safer than BAOSFE in elevating the Schneiderian membrane” for elevation heights of 7 mm.
More than half of the implants placed in the posterior maxilla require sinus floor elevation (SFE) [1]. The need for this procedure is explained by continuous ridge resorption in an apical direction after tooth extraction combined with progressive sinus pneumatization in addition to poor bone quality that is frequently seen in the maxilla [2].
Sinus membrane perforation is considered the most com...
Various techniques are available for elevating the sinus membrane. The aim of this study is to evaluate three methods of indirect sinus floor elevation regarding elevation heights of 7 mm on the outcomes of membrane perforation, length of perforation, and time required to perform the procedure.
Three different methods for indirect sinus lifting, bone added osteotome sinus floor elevation (BAOS...

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...

Depending on the observers’ clinical and radiological experience, PAN alone may not be sufficient for evaluation of pathologies of the maxillary sinus. On the contrary, significant benefits of sFOV-CBCT for diagnosing symptomatic maxillary sinus pathologies were reported. Having sFOV-CBCT seems to have added additional information and confidence in comparison to PAN alone. Nonetheless, also with...
The influence of clinical experience of evaluation of PAN [34] as well as the clinical experience and routine analysis of 3D radiographs (as assumed for maxillofacial surgeons when compared to those for general practitioners) strongly influence the diagnostic value of additional three-dimensional imaging. The number of incidental findings in CBCT in addition to those seen in PAN was not of major d...
In dentistry, PAN is a widely available, useful, and important diagnostic tool for diagnosis and general preoperative planning [32] with less radiation exposure then CBCT [21]. While most dentists have used it routinely successful for years and gained significant experience in doing so [33], there are certain limitations in dependence of the region to be examined [10]. The high number of “not vi...
This study focused on three different aspects in our analysis—PAN, PAN and CBCT, as well as the influence of the different clinical and radiological experience (examples in Figs. 1 and 2).
Panoramic radiography (PAN)
When assessing PAN, the ratings were significantly lower at “good visible and can be evaluated” (9.9%) compared to “visible but cannot be evaluated” (39.5%; p
The first question for PAN addressed the imaging quality in the clinical relevant area of interest (clinical data were given). Three answers were possible: 1 = good visibility and can be evaluated, 2 = visible but cannot be evaluated, and 3 = not visible. The second question asked for an additional need for CBCT scans. Three answers were possible: 1 = required, 2 = reasonable, and 3 = not required...
In an experimental diagnostic comparison, radiographic images of 15 female and 13 male patients were assessed. Patients’ radiographs were selected from the Department of Oral, Maxillofacial and Facial Plastic Surgery of the University Medical Centre of Mainz and Rostock, Germany. All patients have had referrals to the hospitals with symptomatic maxillary sinus pathologies and received PAN (Ortho...
In order to justify CBCT use for clinical examination and diagnosis of the maxillary sinus, the aim of this study was to compare the subjective quality rating of PAN and PAN together with a small field of view (sFOV) CBCT to evaluate symptomatic maxillary sinus by clinicians with different training and clinical experience.
Non-symptomatic abnormalities of the maxillary sinus such as mucosal thickening, retention cysts, and opacification are reported to occur in up to 74% of all cases [1–6]. For diagnosis of symptomatic pathologies of the maxillary sinus like retention cysts, polyps, and tumors, panoramic radiographies (PAN) are commonly used and widely available. In PAN, not every area of interest is accurately de...
A comparison of panoramic radiography (PAN) alone and PAN together with small field of view cone beam computed tomography (sFOV-CBCT) for diagnosis of symptomatic pathologies of the maxillary sinus was carried out by clinicians of different experience.

The present study showed that maxillary sinus floor augmentation with BC resulted in adequate amounts of new bone formation allowing successful implant installation, while adding EMD did not have a significant effect.
Nevertheless, the amount of bone generated with BC or BC + EMD herein was adequate to support successful implant placement and osseointegration of implants. In fact, more or less similar amounts of bone formation have been reported in studies evaluating human sinus biopsies after grafting with a variety of biomaterials (bone formation ranging approximately from 30 to 50%) [19]. On the other ha...
The present study compared the histological and histomorphometrical outcome of healing after maxillary sinus floor augmentation with BC with or without EMD, based on human biopsies. The results showed that addition of EMD did not enhance the outcome of healing, neither in terms of quality nor quantity of new bone. Nevertheless, the amount of bone generated after maxillary sinus floor augmentation ...
All ten patients showed uneventful healing after the sinus floor augmentation procedure as well as after dental implant placement, with no overt postoperative inflammation or infection. Consistently, in all ten patients, no significant jiggling of the drill was noticed during biopsy harvesting, while subjective drilling resistance during implant placement was similar in both groups and all implant...

Six months after grafting, another CBCT examination was carried out for implant planning.

The aim of the present study was to compare histomorphometrically the outcome of maxillary sinus floor augmentation with β-TCP/HA with or without enamel matrix proteins (BC + EMD and EMD, respectively) in humans.
Reconstruction of the edentulous and severely atrophied posterior maxilla is often performed by means of maxillary sinus floor augmentation in combination with dental implants [1, 2]. Various bone graft materials are typically used for enhancing bone formation within the sinus cavity; autogenous bone (AB) is considered as the gold standard due to its osteogenic, osteoinductive, and osteoconductive...
It is still unclear whether enamel matrix proteins (EMD) as adjunct to bone grafting enhance bone healing. This study compared histomorphometrically maxillary sinus floor augmentation (MSFA) with β-TCP/HA in combination with or without EMD in humans.
In ten systemically healthy patients needing bilateral MSFA, one side was randomly treated using β-TCP/HA mixed with EMD (BC + EMD) and the ot...

An amendment to this paper has been published and can be accessed via the original article.
Within the limitation of this study and that of an ex vivo study, we can accept our hypotheses that the balloon is better than the BAOSFE in elevating the membrane mucosa and the CAS kit is better than the BAOSFE in preparing the osteotomy and breaking the sinus floor for elevation heights of 7 mm. Further, in vivo studies need to be taken to prove these findings.
The BAOSFE technique caused perforations in the membrane in 7 out of 12 cases with a percentage of 58.4. This result is consistent with many previous studies which state that this technique has a high rate of perforations when the RBH is less than 5 mm [2, 7, 26]. Also, all the perforations happened during the elevation process; however, this percentage is different than that reported by Steltzle...
Using a reamer instead of the osteotomes for breaking the sinus floor has the advantage of creating a thin bone shell that prevents direct contact between the drill and the Schneiderian membrane [24]. Moreover, using a reamer has been shown to cause less discomfort and nausea when compared to the osteotome technique as a result of the constant tapping of the osteotomes [25]. As a result, the CAS k...
Although the lateral sinus floor elevation is a proven clinically successful technique [14], the indirect SFE approach is favorable among clinicians because it does not require a second surgery site and hence cause less trauma and discomfort for the patient [14,15,16]. However, this method has its drawbacks, such as a higher risk of membrane perforation, a decreased space for using surgical instru...
For the entire sample, the mean perforation length was (0.711 mm, SD = 1.4) and the mean time required to perform the procedure was (5.65 min, SD = 2.26), and out of the entire sample (N = 36), perforations happened in nine cases for a percentage of 25%.
Chi-square test showed a significant association between method used and the occurrence of perforation (chi-square statistic = 8.585, ...
This approach starts like BAOSFE. The osteotomy is enlarged to 5.0 mm before the balloon (Zimmer Sinus Lift Balloon, Zimmer Dental Inc., California, USA) is inserted (Fig. 3). The sinus floor was broken with the 5 mm osteotome after the addition of bone. The sleeve of the balloon was inserted 1 mm beyond the sinus floor. The saline was injected slowly from the syringe into the balloon, so the ...
To achieve our purposes, an experimental ex vivo study was carried. This research project was approved by the University of Damascus Local Research Ethics Committee (UDDS-3045PG.) and was funded by the Damascus University Postgraduate Research Budget (97687027834DEN). The sinus floor elevations were done on 18 bisected heads of lambs aged between 6 and 12 months that were slaughtered in a maximum...
Therefore, the two working hypotheses of our study were “the CAS-Kit is safer than BAOSFE in breaking the sinus floor and the balloon is safer than BAOSFE in elevating the Schneiderian membrane” for elevation heights of 7 mm.
More than half of the implants placed in the posterior maxilla require sinus floor elevation (SFE) [1]. The need for this procedure is explained by continuous ridge resorption in an apical direction after tooth extraction combined with progressive sinus pneumatization in addition to poor bone quality that is frequently seen in the maxilla [2].
Sinus membrane perforation is considered the most com...
Various techniques are available for elevating the sinus membrane. The aim of this study is to evaluate three methods of indirect sinus floor elevation regarding elevation heights of 7 mm on the outcomes of membrane perforation, length of perforation, and time required to perform the procedure.
Three different methods for indirect sinus lifting, bone added osteotome sinus floor elevation (BAOS...

Velasco-Torres et al. [19] showed a larger sinus volume for dentate patients compared to edentulous and partially edentulous patients. This may be explained through the loss of posterior teeth in the maxilla, leading to the reduction of mechanical stimulation of the maxillary sinus. As a consequence, the sinus could expand (pneumatization) due to increased pressure and ostoclastic activity of the ...
The aim of this study was to analyze volume parameters of the maxillary sinus based on CBCT data. Further, neighboring anatomical structures and related pathologies were recorded. Overall, the applied volume software used in this study allowed the calculation of the surface area and volume of maxillary sinuses.
In clinics, the radiographic evaluation of the maxillary sinus is obligatory prior to ...
No relationship was observed between a patient’s age and the presence of partial or complete obliteration of at least one maxillary sinus (Fig. 6, p = 0.92). Patient’s age and the mean osseus sinus volume were also not associated significantly (Fig. 7, p = 0.20). Both maxillary sinuses (osseus borders) of each patient were quite similar in size (mean difference between left and right...
In total, 128 maxillary sinuses were analyzed. The mean surface area was found to be 39.7 cm2 and the mean volume 17.1 cm3. The mean surface area of the remaining pneumatized cavities of obliterated sinuses was found to be 36.4 cm2 and the mean volume 15 cm3 (Table 1). 42.2% of all sinuses showed an obliteration, and the mean volume of the obliterated sinuses was 5.1 cm3. If there was an obl...
Patient-specific variables like gender, date of birth, and date of CBCT were recorded. The date of the CBCT image was further divided into either being in autumn/winter (1 January 2013–19 March 2013; 22 September 2013–31 December 2013) or spring/summer (20 March 2013–21 September 2013). The maxillary sinus was classified into obliterated or nonobliterated. It was also documented if there was...
In the present study, 64 CBCT images (128 maxillary sinuses), taken between 1 January 2013 and 31 December 2013 at the Department of Cranio-Maxillofacial and Oral Surgery at the University of Zurich, were included. The inclusion criterion of each CBCT scan was the presence of two complete maxillary sinuses; the osseus borders of both sinuses had to be entirely visible.
The scans were performed us...
The precise assessment of the maxillary sinus is important in oral and maxillofacial surgery in cases of traumatology, sinusitis, and dental implantology. After the introduction of cone-beam computed tomography (CBCT) in dental medicine in 1998 [1], the number of clinicians using CBCTs increased constantly. Whereas in 2004, there were only three CBCTs registered in Switzerland, the current number ...
There are few studies measuring the dimensions of the maxillary sinus, being mostly based on computed tomography imaging and rarely being based on cone-beam computed tomography (CBCT). The aim of this study was to measure the 3D osseous and soft tissue defined volume and surface area of the maxillary sinus. Further, possible associations with patient-specific and sinus-related variables were evalu...

Crestal sinus lifting technique is a simple less invasive procedure. Nevertheless, it suffers a serious disadvantage of being a blind technique. Thus, perforation can easily occur without being detected which will lead to later implant failure especially when bone graft is added [1, 12,13,14]. We used endoscopic-assisted evaluation as a dependable method to assess the safety of the Schneiderian me...
On the other hand, assessing the effect of membrane morphology pattern on the perforation risk revealed that the polyp type has the lowest risk of perforation, whereas the irregular type represents the most insecure pattern. There was a relation between different membrane morphology and perforation.
All patients tolerated the procedure without major complications. Minor complications included postoperative swelling, edema, and pain that were managed by antibiotic and anti-inflammatory drugs. All implants were successfully osseo-integrated and loaded after about 6 months.
The floor was lifted without perforation in 83.33% of cases. The lifter was able to raise and stretch the sinus membrane ...
After completing the elevation of the Schneiderian membrane, the endoscope (70° lens) was removed from the lateral wall of the maxillary sinus and re-inserted (with 0°) from the crestal osteotomy site of the implant (Fig. 4) to check the integrity of the Schneiderian membrane, as well as to ensure the absence of any undetected minor perforation (Fig. 5). The implant was finally inserted in the...
Twelve patients (4 males and 8 females) ranging in age from 25 to 60 years were included in the study. All patients have bone height ranging 3–5 mm below the sinus membrane. They all performed closed sinus lifting and simultaneous immediate implant insertion.
Under local anesthesia, the flap was elevated and retracted exposing the crestal and buccal bone. A trephine bur 4 mm diameter on hand...
The evolution of closed sinus lift techniques since 1994 [1] was proposed as a less invasive method for management of atrophic posterior maxillae [2]. However, it is a blind technique that lacks the ability to confirm an intact sinus floor elevation without perforation and thus represented a real shortcoming [3]. Various forms of osteotome lifters were designed to guarantee safe elevation of maxil...

By reviewing the literature, we can conclude that in selecting the surgical approach to close an oroantral fistula, different parameters have to be taken into account, including location and size of fistula as well as its relationship to the adjacent teeth, height of the alveolar ridge, persistence, sinus inflammation and the general health of the patient.

Logan and Coates described a procedure that provided closure of OAF in immunocompromised patients [74].
The oroantral fistula was de-epithelialized under local anesthesia, and the patient wore an acrylic surgical splint continuously for an 8-week period. The acrylic surgical splint covered the fistula and the edentulous area including the hard palate. The investigators reported complete healing o...
Use of guided tissue regeneration has been documented by Waldrop and Semba [71]. This method uses an absorbable gelatin membrane, allogenic bone graft material, and a nonresorbable expanded polytetrafluoroethylene (ePTFE) membrane. After flap reflection, an absorbable gelatin membrane is placed over the OAF with its edges on the bony margins of the perforation, which serve as a barrier for the bon...
The use of a bioabsorbable root analog made of β-tricalcium phosphate for closure of oroantral fistulas was proposed by Thoma et al. [68]. The root replicas were fabricated chair side, using a mold of the extracted tooth [10]. The investigators reported that the healing was uneventful. However, fragmentary roots or overly large defects prevent replica fabrication or accurate fitting of the analog...
Polymethylmethacrylate has been introduced as an alternative technique for closing OAFs [64]. After 24 h of immersion in a sterilizing solution, the polymethylmethacrylate plate is placed over the defect. Mucoperiosteal flaps are then replaced without attempting to cover the acrylic plate. The polymethylmethacrylate plate is removed as soon as the edges become exposed. One of the common disadvant...
Various synthetic materials have been used for OAF closures. Use of gold foil and gold plate for the closure of OAFs was reported for the first time by Goldman and Salman, respectively [59, 60]. It is a simplified technique for the closure of oroantral fistulas. The technique consists of elevating the mucoperiosteum to expose the bony margins of the fistula. Then, the opening is covered with an ov...
Multiple techniques have been described for the closure of OAFs using lyophilized fibrin glue of human origin [53]. In this technique, the fibrin glue is prepared and injected into the socket, together with the collagen sheet. Stajčić et al. stressed the importance of inserting the syringe above the floor of the antrum to protect the clot from airflow [53]. The technique is simple with few posto...
An autogenous bone graft and platelet-rich fibrin (PRF) membrane as a treatment strategy for closure of OAF has also been proposed [50]. PRF is a product of centrifuged blood. The biochemical components of PRF are well-known as factors acting synergistically in the healing process. This includes platelet-derived growth factor (PDGF), whose components are the reason why PRF has anti-inflammatory pr...
Recently, auricular cartilage graft has been used for the closure of OAFs. A full-thickness flap is raised at the defect site [47]. A semicircular incision is then made posteriorly over the conchal cartilage. The conchal cartilage with overlying perichondrium is exposed with a blunt dissection. The harvested auricular graft is then adapted on the defect site and sutured with the surrounding tissue...
A retromolar bone graft is a viable procedure for OAF closure. However, harvesting of a retromolar bone can occasionally be combined with removal of the third molar, which may affect acceptance of the procedure by patients [44]. When compared to chin bone grafts, the significant disadvantage of the retromolar donor area is the confined amount of bone available [45]. The incision is made medial to ...
The tongue is an excellent donor site for soft tissue defects of the oral cavity, due to its pliability, position, and abundant vascularity. Tongue flaps can be created from the ventral, dorsal, or lateral part of the tongue [36]. The surgical design of the flap is dictated by the location of the defect. A lateral tongue flap has been described as a suitable method for the closure of large OAF [37...
Free mucosal grafts (FMG) or connective tissue grafts (CTG) are suitable for the closure of small to moderate size defects in the premolar area as well as small to medium size-persistent defects. In contrast to the techniques described so far, the harvested grafts are not directly vascularized. The flap initially receives its nutrients within the first three postoperative days by diffusion alone, ...
The palatal straight advancement flap is of limited use due to the inelastic nature of the palatal tissue, which reduces its lateral mobility. For the same reason, it is suitable for the closure of minor palatal or alveolar defects [17].
The palatal hinged flap has been used successfully to close small fistula of the hard palate, i.e., those less than 2 cm in diameter in a one-stage operation [1...
Môczáir [14] described closing alveolar fistulas by the buccal sliding flap, shifting the flap one tooth distally. This technique produces only a negligible change in the depth of the buccal vestibule. A drawback of this approach is that it requires a large amount of dentogingival detachment in order to facilitate the shift, which may result in gingival recession and periodontal disease.

A narrative literature review of articles and case reports for oroantral fistula has been conducted in the PubMed databases of published English literature. Articles published until April 2018 were reviewed. In addition to 262 articles on the closure of oroantral, 4 articles on the closure of antrooral fistula in humans, and 5 articles in animals, citations were referenced to identify further rele...
Radiologically, in the computed tomography (CT) or cone beam computed tomography (CBCT), the oroantral fistula might show as sinus floor discontinuity, opacification of the sinus, or communication between the oral cavity and the sinus. In addition, focal alveolar atrophy and associated periodontal disease may be observed [6]. In chronic OAF, there is generalized mucosal thickening. Recent studies ...
An oroantral fistula (OAF) can be defined as an epithelialized pathological unnatural communication between the oral cavity and the maxillary sinus [1]. The term oroantral fistula is used to indicate a canal lined by epithelium that may be filled with granulation tissue or polyposis of the sinus membrane [2]. They can arise as late sequelae from perforation and last at least 48–72 h. An oroantr...

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...

This systematic review and subsequent meta-analysis follow the guidelines of the PRISMA statement.
The following focus question was developed: Is the intrusion of dental implants into the sinus cavity during implant drilling or implant placement, without regenerative procedure (lateral sinus lift or transalveolar technique) and graft material, has an effect on implant survival or increase clinica...
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...
After tooth loss, the posterior maxilla is usually characterized by limited bone height secondary to pneumatization of the maxillary sinus and/or collapse of the alveolar ridge that preclude in many instances the installation of dental implants. In order to compensate for the lack of bone height, several treatment options have been proposed. These treatment alternatives aimed at the installation o...

The authors concluded that in clinical decision-making regarding donor site for bone graft harvesting, patients and clinicians should consider expected decrease in HRQoL if deciding to use extra-oral donor sites. Therefore, the authors recommended to prefer intra-oral donor sites whenever possible. In a recent study of Nickenig et al., OHIP-G 21 was evaluated in 8689 patients with variou...
In this prospective study, health-related quality of life questionnaire was given to 76 patients evaluating patient perception of recovery in the four areas pain, oral function, general activity, and other symptoms. The results showed that average and maximal pain peaked on post-operative day 1 and improved on post-operative days 4 and 5. Difficulty in mouth opening was greatest on pos...
Discussion
The clinical and radiological outcomes of sinus augmentation procedures have been published in several studies. 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 ...
In the subcategory physical and psychological disabilities, all questions had significant better values after the sinus lift (p
Results
Survival analysis
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...
Methods
Study design and subjects
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 stu...
Background
Rehabilitation of completely and partial edentulous patients with dental implants has proved to be a safe and predictable procedure. However, reduced bone height and the proximity of the maxillary sinus are challenging limitations for dental implant placement in the posterior maxilla. Besides the use of short and tilted implants, one of the most frequently used surgical techniques fo...
Abstract
Background
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.
Methods
Three hundred sixteen patients treated with an external or internal maxillary sinus augmentation and a total of 863 implants in the Department of Oral and Maxi...

Discussion
Insertion of endosseous dental implants is usually associated with a low incidence of complications and excellent prognosis. However, physiologic changes following tooth loss may complicate or even impede insertion of dental implants in the upper jaw. Furthermore dental implants can only be inserted if there is sufficient bone for adequate stabilization. Therefore, in severely at...
Background
Endosseous dental implants are commonly used to rehabilitate fully or partially edentulous patients. The insertion of such implants can in some cases cause complications, especially in the edentulous atrophic maxilla. In this paper, an unusual complication of altered nasal airflow after the placement of an endosseous dental implant in the maxilla is presented. Subsequent treatmen...
Altered nasal airflow: an unusual complication following implant surgery in the anterior maxilla
Abstract
Dental implants have been in routine clinical use for over three decades and are a predictable treatment modality. However, as with all other aspects of dentistry, complications occur. A 50-year-old female patient with complaints of a long ongoing unpleasant altered nasal airflow presented...

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...

Introduction
The edentulous posterior maxillary region often presents with unique challenging conditions in implant dentistry. 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 ...

Abstract
Background
After tooth loss, the posterior maxilla is usually characterized by limited bone height secondary to pneumatization of the maxillary sinus and/or collapse of the alveolar ridge that preclude in many instances the installation of dental implants. In order ...
