Abstract

This case report discusses osteotome sinus floor elevation (OSFE) and immediate placement in 2 stages in severely resorbed alveolar bone height in which multiple implant placement is not otherwise feasible due to a lack of initial stability. The first implant placed using OSFE without bone grafting prepares the adjacent resorbed sites for further implant placement in the sinus areas, which allows for better initial stability and early functional loading. This process avoids the conventional extensive lateral approach for sinus lifting and bone grafting procedures even in extremely resorbed alveolar bone.

Highlights

Osteotome sinus floor elevation (OSFE) is a widely practiced technique for elevation of the maxillary sinus prior to implant placement [1, 2]
Jensen recommended that the procedure should be performed with simultaneous implant placement when a residual subsinus alveolar bone height (RSBH) of at least 5 mm is present [5]
We report a case of multiple implant insertion on a severely resorbed alveolar bone height in a staged manner in which the first implant is placed by tenting the sinus membrane using OSFE without a bone graft to prepare the adjacent resorbed sites for further implant placement in the sinus areas, which allows for better initial stability and early functional loading

Summary

Introduction

Osteotome sinus floor elevation (OSFE) is a widely practiced technique for elevation of the maxillary sinus prior to implant placement [1, 2]. Jensen recommended that the procedure should be performed with simultaneous implant placement when a residual subsinus alveolar bone height (RSBH) of at least 5 mm is present [5]. The implant is inserted simultaneously with a sinus lift procedure when sufficient primary stabilization can be expected [7, 8]. Attaining initial stability in cases of severely resorbed bone is difficult and is often complicated by fractured residual bone during multiple implant insertion. We report a case of multiple implant insertion on a severely resorbed alveolar bone height in a staged manner in which the first implant is placed by tenting the sinus membrane using OSFE without a bone graft to prepare the adjacent resorbed sites for further implant placement in the sinus areas, which allows for better initial stability and early functional loading
