The aim of the study was to assess possible risk indicators for peri-implantitis at different levels of severity using multi-level analyses.
One hundred and nine subjects attended the examination, 69 females and 40 males. Mean time of implants in function was 8.4 years (standard deviation 4.6) (subject level). The participants were examined clinically and radiographically. Information regarding general health and habits was gathered, with special emphasis on smoking, oral hygiene and susceptibility to periodontitis. The relation between possible risk indicators and the following features were assessed: • Detectable peri-implantitis: detectable radiographic bone loss (>0.4 mm) and inflammation • Overt peri-implantitis: radiographic peri-implant bone loss 2.0 mm and bleeding on probing /suppuration at pocket probing depth 4 mm.
Multi-level statistical analyses identified location in the maxilla as risk indicator for detectable peri-implantitis. Regarding overt peri-implantitis, gender (male) and history of periodontitis were identified as risk indicators.
Individuals with a history of periodontitis were prone to peri-implantitis, peri-implant bone loss ≥ 2.0 mm and overt in the present study. No association was found between smoking and peri-implant disease in the present study population.
本研究旨在使用多水平分析评估不同严重程度的种植体周围炎的可能风险指标。
109 名受试者接受了检查，其中 69 名女性和 40 名男性。种植体功能的平均时间为 8.4 年（标准差 4.6）（个体水平）。参与者接受了临床和影像学检查。收集了有关一般健康和习惯的信息，特别强调了吸烟、口腔卫生和牙周病易感性。评估了可能的风险指标与以下特征之间的关系：•可检测的种植体周围炎：可检测的放射学骨丧失（>0.4 毫米）和炎症；•显性种植体周围炎：放射学种植体周围骨丧失 2.0 毫米，探诊深度为 4 毫米时探诊出血/溢脓。
多水平统计分析确定上颌骨位置为可检测种植体周围炎的风险指标。关于显性种植体周围炎，性别（男性）和牙周病史被确定为风险指标。
在本研究中，有牙周病史的个体易患种植体周围炎，种植体周围骨丧失≥2.0 毫米且明显。在本研究人群中，未发现吸烟与种植体周围疾病之间存在关联。
