Graftless Maxillary Sinus Lift Using Lateral Window Approach

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%).

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.

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.
