摘要: 目的:评价“三明治”截骨术用于前牙区种植修复临床效果。方法:使用“三明治”截骨术对6例前牙缺失区垂直骨缺损严重的患者进行骨增量,植骨术后6个月行种植术,3个月后修复。结果:植骨前后对比获得骨高度增加为4.10 mm,3.70~4.40 mm(M,Q25~Q75),差异具有统计学意义(P<0.05)。负载1年后平均骨吸收量0.3 mm。顺利完成9颗种植体植入术并获得较满意的美学修复效果。结论:“三明治”截骨术用于前牙种植修复表现出良好的美学效果,是一种安全可靠的骨增量技术。

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
