Aim: The present study was undertaken to evaluate the effectiveness of maxillary sinus augmentation using lateral approach with simultaneously placed two stage implants. Method and Materials: Sinus augmentation procedure was performed in 14 patients using decalcified freeze-dried bone allograft (DFDBA) block with simultaneous placement of   one implant in each patient using piezo surgical device. Radiographic evaluations using OPG and DVT Scan were performed pre-operatively, after implant placement and at 6 months post-operatively. Clinical parameters recorded around implant were plaque index, bleeding index, probing measurement and Clinical implant mobility at 6 months postoperatively and 3 months after final prosthesis. Results: No complications were observed during the 9 months follow-up period. The mean pre-operative residual bone height was 7.096±2.11mm. At 6 months the mean post-operative bone height was 16.58±1.61 mm with a range of 13.02mm to 18.56mm resulting in mean gain of bone height of 9.60±2.35 (0.000, S) with a range of 4.20mm to 12.97mm. The measurement of the crestal bone levels indicated minimum bone loss during observation period with no episodes of peri-mucositis or peri-implantitis. Conclusion: Sinus augmentation using decalcified freeze-dried bone allograft (DFDBA) block as a space filler was found to be an effective and safe procedure allowing high survival rates of implants placed in the posterior maxilla.
