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 33例 39颗种植体周围炎病例及 2 0例 2 2颗健康种植体的龈下厌氧菌进行分离鉴定。结果 :两组厌氧菌检出率分别为 89 7%与6 3 6 % ,有显著性差异 (p <0 0 5 )。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 。
Objective:The purpose of this study is to make clear the predominant submucosal anaerobes around peri-implantitis,so as to investigate its etiology and pathology.Methods:33 patients with 39 failing implants were selected to examine by means of anaerobic culture method.Besides that we also selectde 20 patients with 22 healthy implants as comparison.Results:Results showed the ratio of anaerobes present im peri-implantitis samples(89.9%)was significantly higher than in healthy ones(63.6%).Conclusion:Peri-implantitis is a flora imballance symptom during the microbial re-colonization and re-establishment around implants after fitted.Gram-negative anaerobes,especially rods,were the most predominant species.
