Clinical Application of “Sandwich” Osteotomy for Implant Restoration at Deficient Anterior Alveolar Ridges

Abstract

Abstract: Objective: To evaluate the final vertical gain at the deficient anterior alveolar ridges using “sandwich” osteotomy. Methods: Six patients with severe vertical bone defects at deficient anterior alveolar ridges were treated with “sandwich” osteotomy bone augmentation and 9 implants were placed after 6 months. The final restorations were delivered 3 months later. Results: The final vertical gain was 4.10 mm (3.70-4.40 mm), which was statistically significant (P<0.05). The average bone resorption after loading for 1 year was 0.3 mm. Nine implants were successfully completed and the restorations achieved satisfactory aesthetics. Conclusion: “Sandwich” osteotomy has got good aesthetic effect at anterior and is a safe and reliable bone augmentation technique.

Key words: “sandwich” osteotomy, bone defect of vertical ridges, implant restoration
