Background: The present study is designed to compare the outcomes of two sinus augmentation procedures: distal displacement of the anterior wall versus standard sinus lifting and grafting with a lateral window approach. Methods: In the displacement group, a localized surgical fracture of the sinus floor achieved through an electromagnetic device results in the distal displacement of the anterior wall. In the filling group, sinus lifting (with lateral access) and grafting with particulate xenogeneic bone substitute was performed. Bone volume beneath the maxillary sinus was investigated with computerized tomography after baseline and postoperative data superimposition. Clinical and radiological outcomes over three years had been evaluated. Results: Forty-three dental implants were selected. The two sinus lift procedures significantly increased the bone volume (p-value ≤ 0.0017) in the displacement group from 1.17 ± 0.34 to 1.53 ± 0.39 cc, with a final bone gain of +0.36 ± 0.17 cc, and in the filling group from 1.24 ± 0.41 to 1.94 ± 0.68 cc, with a bone augmentation of +0.71 ± 0.31 cc. No events of dental implant bulging into the maxillary sinus occurred. Two implants failed early on in the filling group, attesting the 3-year survival rate of 92.6% (CI95%: 82.7–100%). Marginal bone loss at the distal aspect was 1.66 ± 0.72 and 1.25 ± 0.78 mm, respectively, for the displacement and filling groups, with a significant difference (p-value = 0.0497). Conclusion: Results showed a significant and effective bone gain around dental implants at a 3-year survey for both sinus augmented by backward displacement of the anterior wall (+34%) and sinus lifting and grafting with a lateral window approach (+57%).

Abstract Background To compare a sinus augmentation procedure with a distal displacement of the anterior wall to a standard sinus lifting and grafting with a lateral window approach. Methods In the displacement group, a sinus surgical fracture results in the distal displacement of the anterior wall by means of an electromagnetic device. In the filling group, a sinus lifting with lateral access and grafting with particulate bone was performed. Bone volume beneath the maxillary sinus was investigated with Computerized Tomography after data superimposition. Clinical and radiological outcomes over 3 years had been evaluated. Results Forty-three dental implants were enrolled. The surgery of both groups significantly increased the bone volume in the VOIs (p-value≤0.0017) respectively for displacement group from 1.17±0.34cc to 1.53±0.39cc with a final bone volume gain of +0.36±0.17cc and for filling group from 1.24±0.41cc to 1.94±0.68cc with a bone augmentation of 0.71±0.31cc. Two implants early failed in the filling group, attesting the 3-year survival rate to 92.6%(CI95%: 82.7%-100%). Marginal bone loss at the distal aspect was 1.66±0.72mm and 1.25±0.78mm for displacement and filling group, respectively (p-value=0.0497). Conclusions The study showed an effective bone gain around dental implants at 3-year of survey both for sinus augmented by backward displacement of the anterior wall (+34%) and by sinus lifting with a lateral window approach (+57%).

Abstract Background The presence of septa increases the risk of Schneiderian membrane perforation during sinus lift procedure, and therefore, the chance of graft failure increases. We present a safe method of managing septa and, in particular, overcoming small and palatally located septa. Methods After the elevation of the flap and the creation of a small bony window positioned anterior to the septum, the Schneiderian membrane is lifted carefully. A thin and narrow osteotome is then placed at the indentation created at the base of the septum, and mobilization of the septum is achieved by gentle malleting. The membrane is again carefully lifted up behind the septum. Results There was one small membrane perforation case in all 16 cases, and none of these patients showed postoperative complications such as implant failure, infection, or maxillary sinusitis. Conclusions This technique is useful for overcoming the problem of maxillary sinus septa hindering the sinus floor elevation procedure, leading to fewer complications.

Context: Edentulous patients under the use of removable prosthesis face important restrictions, including sociocultural ones and, for this reason, the insertion of implants has become frequent in clinical dental practice. However, the success of the method will depend on the sort of different types of bone grafting, quality of donor area and the residual amount of bone left in insertion site. Purpose: the purpose of this study was to evaluate the effectiveness and safety of different types of bone grafts used in maxillary sinus lifting surgeries for implant insertion. Methods: systematic review of randomized clinical trials or quasi-randomized. We used the guidelines of the manual of systematic reviews from Cochrane Collaboration and a sensitive search strategy in three electronic databases has been built. Results: We included six randomized clinical trials from different regions of the world with 135 participants. Bone volume was 3% higher on the grafted site with autogenic bone pure, but not a statistically significant difference DM: 3 (-8.48-14.48), the average percentage between the vital and non-vital bone showed up 0.82% higher on the grafted site with FDBA + PRP. The average percentage of vital tissue was also 15.8% higher on the side where PRP was used. Conclusion: the available evidence is insufficient to recommend a specific type of bone grafting in sinus augmentation (lift) procedures to place a dental implant. There was no statistically significant difference for bone volume, sensory loss, local inflammatory response and loss of implants, among others. For this reason, new randomized controlled trials that evaluate the effectiveness and safety of different types of bone graft for lifting of the maxillary sinus are necessary.

Introduction: Measurement of different dimensions of maxillary sinus and anterior wallthickness of maxillary sinus by Computed Tomography in normal Nepalese populationMethods: Dimensions of 90 patients were measured in CT PNS using Syngovia Software. AP diameter, width and anterior wall thickness were measured in axial images and height was measured in coronal images.Results: The mean volume of maxillary sinuses in study of male population on left and right side were 17.09 cm3±3.89, 17.19 cm3 ±4 respectively whereas in female were 15.64 cm3±3.5 and 15.21cm3±3.2 respectively as shown in Table 1. This shows the volume of male was significantly larger than female with P- Value = 0.012 (<0.05). Similarly, the thickness of Anterior Wall (AW) of maxillary sinus was also measured in this study and the mean value of left and right side in male were 0.16cm± 0.04 and 0.15cm± 0.03 respectively and in female were 0.12cm± 0.04 and 0.14cm± 0.02 respectively.Conclusion: This study showed that CT is a reliable method for the measurement of different dimensions of the maxillary sinus. The result showed greater mean value of volume in male than female with significant differences. So this study concluded that the measurement of volume of maxillary sinus can help in the identification of gender which can be very useful for forensic sciences.

Sinus Lifting

The posterior maxilla is indubitably the site reported with highest failures in implant literature so far as the bone availability beneath the sinus poses a major challenge for surgeons. Sinus lift both by direct and various indirect accesses were hitherto utilized to counter the compromising situation. But the risk of implant failure if the implant was simultaneously placed besides the parasthesia, perforation and morbidity were experienced more with more the cases documented. The osseodensification(OD), a relatively new technique provides a minimally invasive approach along with feasibility where the above-mentioned other modalities are contraindicated. The present article presents the novel case of indirect sinus lift with OD concept and simultaneous implant placement using an adjunct PRF (Platelet-rich fibrin).

Tissue Trauma

Maxillary sinus is the first paranasal sinuses to develop, which is pyramidal in shape and it completes developing around 20 years of age with the eruption of the maxillary third molars. Pneumatization of the maxillary sinus occurs with time. Tooth loss may lead to loss of bone density, atrophy of bone and further pneumatization of the maxillary sinus leading to insufficient quality and quantity of bone for placing implants. Despite lots of literature and research being done, there is no clarity in obtaining consensus regarding the techniques and materials used in maxillary sinus lift procedures. This article reviews the various techniques and bone graft materials used in maxillary sinus lift procedures. The techniques include lateral window approach, hydraulic sinus lift technique, Piezoelectric Surgery technique, Transcrestal Approach, Osteotome Technique, and Balloon elevation technique. It can be concluded that the balloon antral elevation technique and Hydraulic Sinus Lift technique are more efficient techniques for maxillary sinus lift procedures. These techniques are known to result inless perforations, less chair-side time, comparatively easier, and the need for elaborate instrumentation is minimized. It can also markedly increase the success rates of implants in contrast to the conventional techniques which pose greater risks to the patient, more soft tissue trauma, more chair-side time and can expose patients to infections.
