摘　　要：目的：为了探讨种植体周围炎的病因及发病机制，明确其龈下优势厌氧菌群。方法：运用厌氧培养技术，对３９例种值体周围炎的龈下标本进行厌氧菌的分离与鉴定，另外还选取了２２例健康种植体及３０例牙周炎作对照。结果：种植体周围炎组厌氧菌检出率（８９．７％）显著高于健康对照组（６３．６％）（Ｐ＜０．０５），而与牙周炎组（９０％）则无显著性差异（Ｐ＞０．０５），并发现不同临床症状的种植体周围炎病例其龈下的所得厌氧菌株的构成比有显著性差异。结论：本文认为种植体周围炎是种植后细菌再定植过程中的一种菌群失调症，Ｇ－厌氧菌为其龈下优势厌氧菌群。Objective: The purpose of this study is to make clear the predominant submucosal anaerobes of periimplantitis, so as to investigate it's etiology and pathology. Methods: 39 failing implants were selected to examine by means of anaerobic culture method. Besides that we also selected 22 healthy implants and 30 teeth with periodontitis as comparison Results: Results showed the radio of anaerobes present in periimplantitis samples(89.9%),as well as peridontitis group (90%), were significantly higher than in healthy ones(63.6%). And during the different phases, the bacteria distribution pattern was also changed. Conclusions: Periimplantitis is a flora imballance symptom during the microbial recolowization and reestablishment around implants after fitted. Gramnegative anaerobes was the most predominant submucosal bacteria species.
