Dental implants represent the majority of treatment strategies used to replace missing teeth. However, peri-implant diseases caused by disturbance in peri-implant microbiological balance are among the reasons for implant failure. Since the 1980s, peri-implant microorganisms have been a hot research topic in dental microbiology. The bacterial ecology between the disease and health largely differs, which directly or indirectly increases the risk of peri-implant diseases. Accordingly, the determination of the 'core microbiome' of peri-implantitis and peri-implant mucositis is a key point of recent research.
牙种植术是目前修复牙列缺损和牙列缺失的主要治疗方案，但是种植体周围微生态失衡易造成种植体周围疾病的发生，进而导致种植失败。从20世纪80年代开始，种植体周围微生物的研究就成为了口腔微生物研究的热点之一。正常种植体周围微生物和种植体周围炎症相关微生物存在着差异，这些差异直接或间接增加了种植体周围疾病的风险，因此寻找种植体周围黏膜炎和种植体周围炎“核心微生物组”是目前研究的关键。.
