摘要
目的比较埋植型与非埋植型种植两种不同方式之间种植体-骨界面组织学反应的异同。方法选用成年杂种犬8只,在其下颌分别植入埋植型与非埋植型种植体,在种植术后1、2、4和12周分别处死动物,采用HE染色对埋植型与非埋植型种植体-骨界面愈合过程进行动态观察,比较两者骨界面改建的异同。结果不同实验时间的结果均显示埋植型与非埋植型种植其新骨形成的速度与骨性结合的程度基本一致。结论非埋植型种植体尽管植入后基桩在整个愈合过程中承受了一定的咬合力,但它能与埋植型种植体一样获得良好的骨结合。
Objective To compare the characteristics of histological reaction at the implant-bone interface after submerged and nonsubmerged implant remodeling in dogs. Methods Eight adult mongrel dogs were used to establish the animal model for submerged and nonsubmerged implants into the bilateral mandibular sites. At 1, 2, 4, and 12 weeks postoperatively, 2 dogs were sacrificed at each time point for histological observation of the healing and remodeling process at the implant-bone interface by HE staining. Results No distinct difference in the rate of new bone generation and degree of osseointegration was observed between dogs with submerged and nonsubmerged implant at each time point. Conclusion In spite of the bite force imposed on the abutment to some extent during the healing process after nonsubmerged implant plantation, favorable osseointegration similar to that after submerged implants can be achieved.
