自体骨碎末与复合移植修复种植体周围骨缺损的比较研究

目的：研究自体骨碎末与混入Bio-Oss复合移植修复种植体周围骨缺损的效果。方法：9周及16周后对种植体周围骨缺损处植入自体骨末、自体骨末与Bio-Oss二者1：1混合骨末及未植骨进行比较。结果：植入的自体骨碎末恢复了一定的骨缺损，混合Bio—Oss组恢复最佳。各组16周时骨整合均优于9周。结论：植入钻孔时收集的自体骨碎末对于恢复种植体周围少量的骨缺损，是完全可行的。自体骨碎末作为供骨量不足时，可以混合适当的Bio—Oss颗粒行复合移植，效果更为理想。

Comparison of Autogenous Chip Bone and Mixture Bone in Treating Bone Defect around Dental Implant

Objective:To study the effect of autogenous chip bone and the mixture of chip bone and Bio-Oss in treating bone defect around dental implant.Methods: We compared the groups with grafting autogenous chip bone,the mixture of chip bone and Bio-Oss and negative control after implanting 9 weeks and 16 weeks.Results: Chip bone restored some bone defects,but the mixture group was the best.Osseointegration was better in 16 weeks.Conclusion: It is feasible to treat small bone defects around implant with autogenous chip bone.When bone defects are relatively large,it's better to apply mixture of chip bone and Bio-Oss.
