ABSTRACT
Background & Objective: The present study was conducted with the aim to clinically and radiographically evaluate the efficacy and efficiency of the direct sinus lift with simultaneous implant placement and bone grafting, and to evaluate bone height with the merits and demerits of lateral approach for sinus membrane elevation. Methodology: This randomized prospective study consisted of 10 patients who met the inclusion and exclusion criteria. The patients were selected irrespective of the age, sex & socioeconomic status, with the residual alveolar bone height between 1 to 4 mm in the edentulous posterior maxillary region. Direct sinus lift was carried out with simultaneous implant placement. Bovine graft (xenograft) was used as a sole grafting material. Patients were followed up for 36 months of prosthetic rehabilitation. Results: Pre-operative alveolar bone height was on an average 2.9 mm (ranging from 1 to 4 mm) with the standard deviation of 0.67 mm. After 36 months of loading, there wasn’t any clinical or radiographical complication. On an average 13 mm bone height was evident (ranging from 11.5 to 14 mm) with the standard deviation of 0.81 mm. Conclusion: Direct sinus lift is an excellent technique for the rehabilitation in the cases with severely atrophic posterior maxilla.
