本研究的目的是比较实验性牙龈炎和实验性种植体周围粘膜炎发展过程中的临床和微生物（显微镜）参数。20例部分无牙患者接受了中晚期牙周病治疗。在积极的牙周治疗，包括动机，指导口腔卫生习惯，刮治和根面平整和牙周手术，如有指征，IMZ口腔种植体被纳入后牙区。愈合3个月后，将修复基台连接起来，并密切监督患者再愈合3个月。此时，获得基线数据。计划在3个月和6个月时进行复查。在此之后，要求患者避免口腔卫生习惯3周。在所有检查中，包括无口腔卫生期结束时，获得以下临床参数：菌斑指数、牙龈指数和龈沟出血指数，均由Mombelli等人（1987）修改。此外，获得粘膜下/龈下菌斑样品并使用相差显微镜进行分析。在3周的菌斑累积期结束时，恢复了最佳口腔卫生。在任何观察期内，种植体与牙齿部位的所有参数平均值之间均无统计学显著差异。没有口腔卫生的时期表现出类似的因果关系之间的细菌菌斑的积累和种植体周围粘膜炎的发展，建立牙龈单位的实验牙龈炎模型。
The purpose of this study was to compare the clinical and microbiological (microscopic) parameters during the development of experimental gingigivitis and experimental peri-implant mucositis. Twenty partially edentulous patients were treated for moderate to advanced periodontal disease. Following active periodontal therapy consisting of motivation, instruction in oral hygiene practices, scaling and root planing and periodontal surgery where indicated, IMZ oral implants were incorporated in posterior edentulous areas. After 3 months of healing, the prosthetic abutments were connected, and the patients were closely supervised for another 3 months of healing. At this time, baseline data were obtained. Re-examinations were scheduled at 3 and 6 months. Following this, the patients were asked to refrain from oral hygiene practices for 3 weeks. At all examinations including the end of the period of no oral hygiene, the following clinical parameters were obtained: Plaque Index, Gingival Index and Sulcus Bleeding Index, all modified by Mombelli et al. (1987). probing pocket depths and recession in mm. Furthermore, submucosal/subgingival plaque samples were obtained and analyzed using phase contrast microscopy. At the end of the 3-week period of plaque accumulation, optimal oral hygiene was reinstituted. There were no statistically significant differences between the mean values of all parameters at implant compared to tooth sites at any observation periods. The period of no oral hygiene demonstrated a similar cause-effect relationship between the accumulation of bacterial plaque and the development of peri-implant mucositis as established for the gingival units by the experimental gingivitis model.
