局部自体骨粉末夹层法修复骨缺损的临床研究

Repair of Bone Defect by Sandwich Method Using Local Autologous Bone Powder

目的：研究刮取局部临近自体骨碎末应用夹层法覆盖种植体表面修复种植体周围骨缺损的效果。方法：种植骨缺损区周围刮取部分皮质骨及松质骨,均匀铺在种植体表面,再放置Bio-Oss骨粉及Bio-Gide膜。结果：覆盖种植体表面的自体骨碎末外加Bio-Oss骨粉恢复了一定的骨缺损,所有种植体骨结合良好,6-9个月行烤瓷冠修复,形态和功能良好,患者满意。结论：在植入区附近刮取粉末状骨可以与种植体形成良好的骨结合,又恢复种植体周围骨缺损,是完全可行的。

Objective： To study the effect of new bone formation around the area of bone defect by covering local autologous bone powder on the surface of dental implant. Methods： Some of cortical bone powder and spongy bone powder scraping from the nearby area of bone defect were laid on the surface of dental implants, then Bio - Oss and Bio - Gide were placed. Results： New bone formation occurred quickly around the area of bone defect and osseointegration formed completely along the surface of the implants. Porcelain crowns were placed after 6 - 9 months and functioned well. Conclusion ： Sandwich method by using local autologous bone powder is feasible for the patients with bone defect around the dental implant.
