[Research progress in microbiological characteristics of peri-implant disease].

Peri-implant disease is an inflammatory status which leads to the destruction of the soft and hard tissues around osseointegrated implants, including peri-implant mucositis and peri-implantitis. It is generally accepted that bacterial infection appears to be responsible for peri-implant lesions. This review aims to summarize the characteristics of the subgingival microbiota in healthy and diseased implants and compare the microbial composition of subgingival biofilm in teeth with periodontal disease and in diseased implant, so as to provide biological basis on the diagnosis, therapy and prevention of peri-implant disease in clinical practice.种植体周围病是指发生于种植体周围软硬组织的感染性疾病，包括种植体周围黏膜炎和种植体周围炎两类疾病，是临床上常见的种植体生物学并发症。大量研究证实，种植体周围软组织炎症和边缘骨吸收的发生与微生物感染密切相关。本文通过回顾有关种植体周围微生物研究的相关文献，总结归纳健康和疾病状态下种植体周围微生物的特点，并对比牙周病患牙与种植体周围病植体龈下微生物的构成，为种植体周围病的诊断、治疗及预防提供依据。.
