Abstract

Background:  A study was done to evaluate the success of implants placed in the deficient posterior maxillary ridges following a vertical augmentation procedure either a direct or indirect sinus lift with immediate implant placement. Materials and Methods: A total of 12 patients were chosen for the study. Patients with a residual alveolar ridge of 8 mm and less in posterior edentulous maxilla were chosen. The implant success was evaluated both clinically and radiographically over 6 months, 1 year and 3 year follow up period. Results: Both direct and indirect sinus lifts are predictable procedures, even though in our study we used both, we more often chose a direct sinus lift procedure and it gave more predictable results owing to the better quality and quantity of grafted bone and its good turnover over 1 and 3 years, Conclusion: both the techniques are equally predictable and with the recent advances that have taken place in the field of equipment, surgical expertise, and know how, better graft material and membranes, sinus lift is a predictable procedure for rehabilitation in the posterior maxilla.
