Several measurements are combined to diagnose peri-implant disease, and different thresholds are used to describe the disease. The purpose of this study was to evaluate the prevalence of peri-implant disease and to apply different diagnostic thresholds to assess its prevalence in relation to severities of peri-implantitis with different degrees of bone loss.
A total of 164 subjects with dental implants inserted at the Institute of Clinical Odontology, University of Oslo, between 1990 and 2005, were invited to join the project, and 109 subjects attended the examination (mean age: 43.8 years; range: 18 to 80 years). The mean functional loading time was 8.4 years (SD: 4.6 years). The participants were examined clinically and radiographically. The following aspects of disease were assessed to describe the peri-implant condition: detectable radiographic peri-implant bone loss and inflammation, the presence of bleeding on probing at a probing depth >or=4 or >or=6 mm, and radiographic peri-implant bone loss assessed at >or=2.0 and >or=3.0 mm.
Assessing peri-implantitis at different levels of severity yielded a substantial variance in prevalence (11.3% to 47.1%) in the present study population.
Peri-implant inflammation was a frequent finding with and without peri-implant bone loss.
有几种测量方法被用于诊断种植体周围疾病，并且使用不同的阈值来描述该疾病。本研究的目的是评估种植体周围疾病的患病率，并应用不同的诊断阈值来评估其与不同程度骨丧失的种植体周围炎严重程度相关的患病率。
共邀请了 164 名在奥斯陆大学临床牙科学院于 1990 年至 2005 年期间植入牙种植体的受试者参加该项目，其中 109 名受试者接受了检查（平均年龄：43.8 岁；范围：18 至 80 岁）。平均功能加载时间为 8.4 年（SD：4.6 年）。参与者接受了临床和影像学检查。为了描述种植体周围状况，评估了以下疾病方面：可检测的种植体周围骨丧失和炎症、探查深度>或=4 或>或=6mm 时的探诊出血、以及评估>或=2.0 和>或=3.0mm 时的种植体周围放射学骨丧失。
在本研究人群中，以不同严重程度评估种植体周围炎会导致患病率有很大差异（11.3%至 47.1%）。
种植体周围炎炎症是一种常见的发现，无论是否存在种植体周围骨丧失。
