本文报道了对３２例行牙种植修复患者的龈沟细菌分析。共检测出十八种细菌，以口腔链球菌群（９０％）和口普氏菌（６２％）为主，细菌学研究结果表明，成功牙种植体周菌斑细菌组成情况与正常牙牙周菌斑细菌组成情况基本相同；与牙周炎一样，细菌感染因素是导致牙种植体周围炎的重要原因。因此，保持良好的口腔卫生状况，对维持牙种植修复体行使正常功能和延长使用寿命，具有重要意义。
This article reports the analysis of gingival sulcus bacteria in 32 patients undergoing dental implant repair. A total of eighteen kinds of bacteria were detected, which belonged to the group of oral streptococcal (90%) and oral Cephalo (62%). Bacteriological studies showed that the bacterial composition of the bacterial plaque in the successful dental implants was similar to that of the normal dental period Bacterial plaque composition is basically the same; as with periodontitis, bacterial infection is an important cause of inflammation around dental implants. Therefore, to maintain good oral health status, to maintain the normal function of dental implants to restore and extend the service life, is of great significance.
