摘　　要：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B io-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。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.
