骨内牙种植体临床效果评价──Ⅲ．龈下细菌定植观察

An Evaluation of Clinical Effects on Endosseous Dental Implant Part──Ⅲ.An Observation of the Bacteria in the Subgingival Groove

采用细菌分离培养方法，对功能负荷后的钛叶状牙种植体和天然牙局部的龈下细菌定植数量及构成比进行了计数并分析。结果显示，各实验程期种植体与天然牙龈下细菌构成比有差异，但主要优势菌群构成比及细菌生长数量比无差异。说明钛叶状种植牙在行使功能中能保持局部的微生平衡，并与天然牙能保持功能协调。这一结论进一步证实了钛叶状种植牙的良好适应植和组织相容性。

Abstract The colonial character of germ which lived in titanium implant teeth vas tested using anaerobic culture. 30 implanted patients whom have weared gold-ceramic crown or bridge prothesis for 1￣30 months were examined. The results indicated:the titanium implant teeth effected the microenviroment of rnouth in varying degrees,but the titanium implant teeth and natural teeth are able to perform functions in cooridination and keep the balance of the microeubiosis.Titanium implant matericimplant material is an ideal artifical material.
