Peri-implantitis is a frequent finding but estimates of its prevalence vary widely. This may be due to the wide variety of disease definitions. In 2017 the World Workshop on Periodontal and Peri-implant Diseases and Conditions established new criteria for disease definitions. The aim of this study is to assess the potential impact of a new definition on the future reporting of peri-implant disease.
Data from a 2015 report of peri-implant prevalence were examined using the new diagnostic criteria. This cross-sectional study was performed on 95 patients with 220 implants who had their implants placed between 1998 and 2003. An examiner masked to the previous diagnosis examined the radiographs and patient data to make a diagnosis based on 3 mm of bone loss from the expected level of bone. This reanalysis was used to calculate the prevalence of peri-implant disease and generate new relative risk indicators.
The mean follow-up time for the patients was 10.9 years. Using the 2017 criteria, peri-implant mucositis was found in 35.3% of the implants and 52.2% of the subjects, and peri-implantitis occurred in 8.7% of the implants and 15.2% of the subjects. This constituted a drop in peri-implantitis at both patient and implant level of nearly 50% from the prior analysis. Smoking at time of implant placement emerged as a new risk factor in this analysis that was not identified in the prior analysis.
The new diagnostic criteria significantly reduce the reported prevalence of peri-implantitis and bring new risk factors into focus.
种植体周围炎很常见，但对其患病率的估计差异很大。这可能是由于疾病定义多种多样。2017年，牙周和种植体周围疾病及状况世界研讨会制定了疾病定义的新标准。本研究的目的是评估新定义对未来种植体周围疾病报告的潜在影响。
使用新的诊断标准检查了2015年种植体周围患病率报告中的数据。这项横断面研究对95名患者的220颗种植体进行，这些种植体于1998年至2003年间植入。一名对先前诊断不知情的检查者检查了X光片和患者数据，以根据距预期骨水平3毫米的骨丢失情况做出诊断。此次重新分析用于计算种植体周围疾病的患病率并生成新的相对风险指标。
患者的平均随访时间为10.9年。使用2017年标准，35.3%的种植体和52.2%的受试者存在种植体周围黏膜炎，8.7%的种植体和15.2%的受试者发生种植体周围炎。与之前的分析相比，这在患者和种植体层面上使种植体周围炎的发生率下降了近50%。在此次分析中，种植时吸烟成为一个新的风险因素，而之前的分析未发现这一点。
新的诊断标准显著降低了报告的种植体周围炎患病率，并使新的风险因素受到关注。
