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).

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.

SummaryIntroduction. An enforcement of atrophic maxilla with biomaterials during sinus-lift surgery improves size and quality of alveolar bone. Radiological densitometric analysis can prove it. Within the study a density of bone was investigated and findings were compared with natural bone around the implants.Aim of the Study.Was to determine if density around the implant inserted with one stage sinus-lift operation using bone substitute materials increase and if that can be detected radiologically.Materials and Methods.Totally there were examined 22 patients where 64 implants were inserted in maxilla: 48 implants were inserted with one stage sinus-lift operation using bone substitute materials; represented study group. Sixteen implants were inserted in natural maxillary alveolar bone of the same patients, representing control group. The density of implant supporting tissue was measured with cone beam computed tomography and expressed in Hounsfield units (HU). The measurements were performed according to standardized pattern.Results.Densitometric measurements were higher in the study group than in the control group in all points, but statistically significant difference was observed in two measurement sites: buccally in sinus elevation area (BSM) (p=0.005) and palatinally in sinus elevation area (PSM) (p=0.0012), and corresponding areas in control group.Conclusions.Surgical elevation of maxillary sinus floor using calcium phosphate bone substitute materials resulted in higher optical density compared to natural bone. Mineralization of the bone, induced by the bone substitute materials, can be detected radiologically

Maxillary Sinus Floor Elevation

The sinus lift is a procedure that is used frequently in oral surgery, different techniques exist to perform this procedure approaches, which allow the surgeon to give a sufficient bone height for planning a rehabilitative treatment with implant at the required site. In this case the unilateral lifting of the maxillary sinus floor by buccal bone window, with subsequent implant placement and lyophilized human bone in a single surgical procedure.

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%).

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.
