摘要: 目的评价基于种植导板的新型双根种植体植入方法的可行性。方法对兔胫骨进行CT扫描,制作种植导板。选择12只新西兰大白兔,在种植导板的辅助下于一侧胫骨植入双根种植体,另一侧胫骨植入单根种植体作为对照组。分别于术后8、12周处死动物,直接观察种植体松动度,标本行X线片检查,通过Image Pro-Plus6.0软件测量种植体周围骨质灰度值;制备含种植体的硬组织切片,通过Image Pro-Plus6.0软件测量种植体-骨界面的骨结合率。采用SPSS20.0软件对数据进行t检验。结果双根种植体植入过程顺利,种植体无明显松动,各时间点实验组和对照组种植体周围骨质灰度值和骨结合率数据差异无显著差异(P>0.05)。结论基于种植导板的双根种植体植入方法操作可行,植入后双根种植体骨结合良好。

Abstract: PURPOSE: To evaluate the feasibility of double-root implantation with the aid of template. METHODS: Implant templates were fabricated based on CT data from the tibia of 12 rabbits. 12 double-root implants were placed in the tibia of rabbits under the guidance of implant templates, and single-root implants were placed in contralateral tibia of the same rabbits. Rabbits were sacrificed at 8 and 12 weeks. Implant mobility was checked directly. Specimens were examined by X-ray to measure bone gray value using Image Pro-Plus6.0 software. Super-rigidity slices were prepared to test bone-implant contact ratio using Image Pro-Plus6.0 software. The data were analyzed with SPSS20.0 software package. RESULTS: The surgical procedures were completed successfully. There was no obvious loosening of implants. No significant difference was found between the experimental and control groups in bone gray value and bone-implant contact ratio at different time(P>0.05). CONCLUSIONS: The implanting method of double-roots implant with the aid of template is feasible, and osteointegration is ideal.
