碳—钛复合体骨内种植的酶组织化学研究

An Enzymohistochemical Study on the Endosseous Implantation of i c Composite

目的：证实碳—钛复合体（ｉ－ｃ）的良好生物相容性。方法：分别将ｉ－ｃ、ＴｉＮ－Ｔｉ、Ｔｉｃ－Ｔｉ和Ｔｉ４种种植体植入６条狗的双侧下颌骨内，术后１，２和４个月处死动物，取材。用酶组织化学方法检测４种不同种植体骨界面处新生骨的代谢程度。结果：ｉ－ｃ植入后成骨活动启动早，植入后２个月即基本达到骨整合。结论：ｉ－ｃ的生物相容性优于其它３种种植体。

Objective:Purpose was to verify the histocompatibility of i c composites.Methods: We implanted i c, TiN Ti, Tic Ti and Ti composites into maxilla bone of 3 dogs, with 24 implants totally. The animals were randomly assigned to 3 groups, and killed in 1, 2, and 4 months respectively after operation. The metablic degree of the new bone at the integration interface was observed and compared by enzymohistochemical method. Results: The implant of i c composite had the earliest inception of bone formation and interface intergration in about 2 months. Conclusions: The implant of i c composite exhibited the best histocompatibility in comparison with the other three composites.
