Clinical, biochemical and microbiological methods were used to study the peri-implant status in different types of dental implant. Sixteen normal healthy adults with 12 one-stage implants and 22 two-stage implants were included in this study. Clinical parameters, proportion of subgingival spirochetes, detection rate of spirochetes were found to be significantly higher around one-stage implants than those around two-stage implants. No significant difference in gingival crevicular fluid flow, levels of aspartate aminotransferase and alkaline phosphatase was found between these two types. The bleeding index score in sites which harbored spirochetes was significantly higher than that in sites without spirochetes. The present data suggested that accumulation of plaque and existance of periodontal pathogens maybe related to peri-implant inflammation. This study suggests that plaque control and regular recall should be emphasized in implant maintenance.
采用临床、生化和微生物学方法研究不同类型牙种植体周围的状况。本研究纳入了16名正常健康成年人，他们共有12枚一期种植体和22枚二期种植体。发现一期种植体周围的临床参数、龈下螺旋体比例、螺旋体检出率显著高于二期种植体周围。这两种类型的种植体在龈沟液流量、天冬氨酸转氨酶和碱性磷酸酶水平上没有显著差异。存在螺旋体部位的出血指数评分显著高于无螺旋体部位。目前的数据表明，菌斑堆积和牙周病原体的存在可能与种植体周围炎症有关。本研究表明，在种植体维护中应强调菌斑控制和定期复查。
