Conclusion : Bone plate repositioned over the antr...

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 ...

Discussion : Bone plate repositioned over the antr...

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...

Discussion : Bone plate repositioned over the antr...

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...

Introduction : Bone plate repositioned over the an...

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...

Conclusion : Bone plate repositioned over the antr...

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 ...

Discussion : Bone plate repositioned over the antr...

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...

Discussion : Bone plate repositioned over the antr...

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...

Results : Bone plate repositioned over the antrost...

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...

Introduction : Bone plate repositioned over the an...

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...

This nongrafted sinus-lifting procedure using an HA/PLLA mesh plate device helps to attain predictable bone formation. Stable membrane elevation by the HA/PLLA device for the long term could contribute to predictable bone formation in the sinus. The source of cell supply could possibly be the Schneiderian membrane, reflecting its osteogenic potential.

In nongrafted sinus-lifting procedure, several devices such as titanium [12–14], hollow hydroxyapatite [15], and bioresorbable materials [16] have been used for space retention to maintain the lifted sinus membrane and the results of predictable bone formation have been reported in addition to histological examination. In this case, a mesh plate device consisting of HA/PLLA materials was applied...

A 60-year-old healthy female, who desired dental implant therapy in the right molar region of the maxilla, was referred to the Department of Oral and Maxillofacial Surgery. Clinical examination revealed an edentulous maxilla from the right first premolar to the second molar region. Panoramic radiography showed atrophy of the maxillary alveolar ridge in the same site (Fig. 1), and the need for sin...

Maxillary sinus lift is a bone augmentation procedure in the sinus that improves the alveolar crest height in atrophic posterior maxilla by forming new bone in the space created under the elevated sinus membrane. To date, numerous grafting materials have been used as a scaffold for new bone regeneration, including autogenous bone, bone graft substitutes, or their combination [1, 2]. Autogenous bon...

Abstract : Continuous intra-sinus bone regeneratio...

Sinus lift is a bone augmentation procedure that improves the alveolar crest height in an atrophic posterior maxilla. However, the regenerated bone volume can vary and generally has a tendency to decrease after sinus operation. This article describes nongrafted maxillary sinus lift using a bioresorbable unsintered hydroxyapatite combined with poly l-lactide (HA/PLLA) mesh plate device and dental i...

A suitable alternative surgical management of this particular case might have been to simply perform an alveoloplasty to produce the desired inter-occlusal clearance and proceed with placement of implant and simultaneous direct sinus lift.

Obtaining proper occlusal clearance to allow for a single unit crown restoration is a fundamental prerequisite for dental implant restoration. Long-standing edentulous sites are often fraught with disuse atrophy and unopposed supra-eruption of the opposing dentition. In the posterior maxillae/mandible, there are vital structures that have to be mobilized in order to allow space for either bone tra...

Dental restorative space from the opposing dentition requires adequate distance for restorative material for an acceptable restoration. Typically, long-standing edentulous alveolar ridges will have vertical and or horizontal defects that require alveolar ridge augmentation for ideal dental implant restorations. Along with these defects, one will see the opposing dentition supra erupt which can obl...

Within the limits of this case-controlled study, it can be concluded that lateral ridge augmentation procedures in atrophic alveolar ridges using bioresorbable matrix barriers without achieving primary flap closure or in the case of early exposures can still lead to clinically satisfying ridge width gain that allows for the placement of dental implants. However, exposures seem to limit the ridge w...

The microbial contamination of the matrix barrier during exposure could be another important factor that might hamper bone formation within the underlying graft. This factor has not been investigated in the present study. However, it has been reported by other groups that the resorbable matrix barrier per se might be less prone to bacterial contamination and can be better cleaned using disinfectan...

Although numerous studies in the literature show successful outcomes of the GBR procedure [6, 31], the most common clinical complication in GBR procedures is early membrane exposure [9].

In this case-controlled study, which was based on a patient subset from ...

Conclusions : Comparison of three different method...

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.

Discussion : Comparison of three different methods...

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...

Discussion : Comparison of three different methods...

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...

Discussion : Comparison of three different methods...

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...

Results : Comparison of three different methods of...

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...

Background : Comparison of three different methods...

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.

Background : Comparison of three different methods...

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.

Within the limits of this case-controlled study, it can be concluded that lateral ridge augmentation procedures in atrophic alveolar ridges using bioresorbable matrix barriers without achieving primary flap closure or in the case of early exposures can still lead to clinically satisfying ridge width gain that allows for the placement of dental implants. However, exposures seem to limit the ridge w...

The microbial contamination of the matrix barrier during exposure could be another important factor that might hamper bone formation within the underlying graft. This factor has not been investigated in the present study. However, it has been reported by other groups that the resorbable matrix barrier per se might be less prone to bacterial contamination and can be better cleaned using disinfectan...

Although numerous studies in the literature show successful outcomes of the GBR procedure [6, 31], the most common clinical complication in GBR procedures is early membrane exposure [9]. There is a general clinical impression that the ridge augmentation results are compromised in the case of early membrane exposures [32, 33]. In this case-controlled study, which was based on a patient subset from ...

Various resorbable membranes exist in the market composing of dura mater, poly-lactic acid, polyglycolic acid, polyurethane, or mostly collagen. Still, even resorbable membranes show frequent events of membrane exposures after GBR procedures. For example, between 22 and 32% of early membrane exposure have been reported for collagen membrane by several authors [15,16,17,18]. A major drawback of col...

It has been reported that unpreserved alveolar ridges can show substantial horizontal and/or vertical ridge deficiency [1, 2] that lack the sufficient alveolar ridge dimensions to allow the ideal positioning of the implant and enhance long-term prognosis of the clinical outcomes [3]. Guided bone regeneration (GBR) is a predictable technique for augmenting the alveolar ridge width that has been use...

The effect of membrane exposure on guided bone regeneration (GBR) for lateral ridge augmentation has been poorly addressed. This case-controlled study aimed to investigate potential effect of membrane exposure lateral ridge augmentation and subsequent implant placement.

Conclusions : Comparison of three different method...

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.

Discussion : Comparison of three different methods...

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...

Discussion : Comparison of three different methods...

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...

Discussion : Comparison of three different methods...

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...

Results : Comparison of three different methods of...

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...

Background : Comparison of three different methods...

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.

Background : Comparison of three different methods...

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.

Atieh [11] found no significant difference in perforation risk. In these studies, occurred in the two groups of the RCTs are almost identical perforations.

The review of Stacchi [12] also described a lower incidence of membrane perforation during piezosurgery (10.9%) than during conventional ...

Though both techniques exist more than 20 years, only single studies could be found in which the incidence of membrane perforation was focused comparing both operative techniques.

In conclusion, and within the limits of its retrospective nature, our study implies that in cases of intraoperative perforation of the Schneiderian membrane, a consequent surgical assessment and treatment might avoid complications regarding graft stability and implant survival. Two-stage procedures might be appropriate if primary stability does not seem to be achievable. Augmentation of the sinus ...

The surgical management in cases of a membrane perforation might also influence the overall postoperative outcome and complications.

To date, most existing studies recommend sealing smaller sizes of perforations with...

Sinus floor elevation procedures have become a predictable and successful treatment, performed when the maxillary alveolar ridge is atrophied and the bone height is not sufficient for primary implantation. If the postoperative course remains uneventful, the outcome is highly predictable [1,2,3]. However, complications may have a negative impact on the overall treatment success. As a common complic...

Abstract : Impact of surgical management in cases ...

Until now, sinus floor elevation represents the gold standard procedure in the atrophic maxilla in order to facilitate dental implant insertion. Although the procedure remains highly predictive, the perforation of the Schneiderian membrane might compromise the stability of the augmented bone and implant success due to chronic sinus infection. The aim of this retrospective cohort study was to show ...

Discussion : Crestal endoscopic approach for 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...

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...

Conclusions : Thickness of the Schneiderian membra...

In conclusion, the present study demonstrated that male patients tend to have a thicker membrane than female patients. The angles of the sinus seemed to increase in width from mesial to distal, and they have no significant correlation with any of our parameters. Thickness of the mucosa and width of the maxillary sinus did not seem to correlate. Future studies including larger groups of participant...

In the present study, it was also concluded that the width of the sinus increases from mesial to distal. Male sinuses had higher prevalence of high angle values compared to female sinuses, but the majority of angle values and widths was characterized as moderate. In an attempt to correlate the membrane biotype regarding thickness with the sinus width, it was proven that there is no correlation be...

Comparing the thickness of the membrane between the two genders, males seem to have thicker membranes than females. Vallo et al. 2010, Janner et al. 2011, Ji-Young Yoo et al. 2011, Cakur et al. 2013, and Jildirim et al. 2017 [9, 11, 12, 16, 17] also come to this conclusion. Our study assumed that this difference is of the order of 40%. On the contrary, Pazera et al. 2010 concluded that there is no...

It is very important to pre-operatively evaluate the thickness of the Schneiderian membrane to plan the surgical procedure in the region that involves the membrane, such as a sinus lift augmentation, which increases the possibility of membrane perforation or other complications. The present study assumed that the average thickness of the Schneiderian membrane is 1.60 ± 1.20 mm. There are m...

The mean value of the overall average thickness is 1.60 ± 1.20 mm (males 1.95 ± 1.28 mm and females 1.24 ± 1.02 mm) (Table 1). The average thickness of the membrane also showed no tendency for differentiation by age group (p = 0.878) (Table 2). The statistical analysis also shows a clear tendency towards lower values when checking from point AR to point CR and from point ...

These three cross-sectional images, in which the thickness of the Schneiderian membrane was previously measured, were also used for the measurement of the angle of the maxillary sinus. A segment DG (point D is the deepest point of the floor of the maxillary sinus) is created, vertical to the horizontal plane with stable length equal to 9.9 mm. The mean of 9.9 mm was chosen, because of a limitati...

The study sample included 76 patients, of which 39 were females and 37 were males. In total, 120 sinuses (44 both left- and right-sided, 21 right-sided, and 11 left-sided) were evaluated as suitable for the present study and were measured. The total sample was classified in four age groups (below 45 years, 45–54 years, 54–64 years, and over 65 years of age). The mean age value of the sampl...

Background : Thickness of the Schneiderian membran...

The maxillary sinus is the largest of the paranasal air-filled spaces, and it develops firstly in utero [1, 2]. Anatomically, the maxillary sinus is a pyramid-shaped cavity located in the facial skull with a mean volume of 12.5 mL (min 5 mL and max 22 mL) [2,3,4,5,6]. The size, the shape, and the wall thickness of every maxillary sinus not only vary among the population, but also between the tw...

The aims of the present study were to determine the thickness of the Schneiderian membrane and identify the width of the maxillary sinus, which is indicated by the buccal and lingual walls of the sinus angle between. Furthermore, to investigate the possibility of a correlation between the aforementioned structures and also other anatomical and demographic parameters using CBCTs for dental implant ...

Despite the shape of a membrane, the PRF membrane does not have the properties of a resorbable barrier membrane [21, 22], due to its fast degradation in the same manner as a natural blood clot (1–2 weeks) [23].
