Peri-implantitis is an inflammatory disease affecting soft and hard tissues surrounding dental implants. As the global number of individuals that undergo restorative therapy through dental implants increases, peri-implantitis is considered as a major and growing problem in dentistry. A randomly selected sample of 588 patients who all had received implant-supported therapy 9 y earlier was clinically and radiographically examined. Prevalence of peri-implantitis was assessed and risk indicators were identified by multilevel regression analysis. Forty-five percent of all patients presented with peri-implantitis (bleeding on probing/suppuration and bone loss >0.5 mm). Moderate/severe peri-implantitis (bleeding on probing/suppuration and bone loss >2 mm) was diagnosed in 14.5%. Patients with periodontitis and with ≥4 implants, as well as implants of certain brands and prosthetic therapy delivered by general practitioners, exhibited higher odds ratios for moderate/severe peri-implantitis. Similarly, higher odds ratios were identified for implants installed in the mandible and with crown restoration margins positioned ≤1.5 mm from the crestal bone at baseline. It is suggested that peri-implantitis is a common condition and that several patient- and implant-related factors influence the risk for moderate/severe peri-implantitis (ClinicalTrials.gov NCT01825772).
种植体周围炎是一种影响牙种植体周围软硬组织的炎症性疾病。随着全球接受牙种植体修复治疗的个体数量增加，种植体周围炎被认为是口腔医学中的一个主要且日益严重的问题。对 9 年前接受种植体支持治疗的 588 名患者进行了随机抽样，并对其进行了临床和影像学检查。采用多水平回归分析评估种植体周围炎的患病率，并确定风险指标。所有患者中有 45%出现种植体周围炎（探诊出血/溢脓和骨丧失>0.5 毫米）。诊断出中度/重度种植体周围炎（探诊出血/溢脓和骨丧失>2 毫米）的患者占 14.5%。患有牙周炎和植入物≥4 个、特定品牌的植入物以及由全科医生提供的修复治疗的患者，其发生中度/重度种植体周围炎的比值比更高。同样，在基线时，下颌骨植入物、冠修复边缘距牙槽嵴骨≤1.5 毫米的植入物，其比值比也更高。研究表明，种植体周围炎是一种常见疾病，一些与患者和植入物相关的因素会影响发生中度/重度种植体周围炎的风险（ClinicalTrials.gov NCT01825772）。
