摘　　要：目的:明确国人种植体周围疾病发病率并探索种植体周围炎的风险因素。方法:收集北京大学口腔医院第二门诊部种植修复后的736例患者的1612枚种植体复查情况,平均负重时间(22.64±0.92)个月,记录种植体周围菌斑指数、探诊深度(probing depth,PD)、探诊出血指数(bleeding index,BI),角化龈宽度,粘接剂残留、骨吸收情况,记录口内天然牙PD、BI。分析不同种植系统及不同复查时间段种植体周围炎的发病率,Logistic回归分析种植体周围炎的相关风险因素。结果:在个体和植体水平,种植体周围黏膜炎发病率分别为81.90%、83.60%,种植体周围炎发病率分别为4.50%和3.70%。各系统间种植体周围炎发病率无显著差异,在修复后1~5年各时间段组种植体周围炎发病率无显著差异,修复后0.5~1年和5~7年发病率显著低于1~5年各时间段组(P<0.05)。Logistic回归分析显示,在调整性别、年龄、吸烟、粘接剂、角化龈宽度等变量后,口内缺牙数、种植体周围PD、BI是种植体周围炎的风险因素(P<0.01)。结论:种植体周围黏膜炎发病广泛,种植体周围炎的发病率并非随着修复时间的延长而增加,对种植体周围探诊深度和出血的控制是预防种植体周围炎发生的关键。Objective：To evaluate the prevalence of peri-implant disease and identify the risk indicators for periimplantitis in Chinese population.Methods：One thousand six hundred and twelve implants in 736patients were enrolled which were placed and restored in the second dental center of Peking University School and Hospital of Stomatology,mean loading period（22.64±0.92）months.The periodontal parameters including plaque index（PLI）,probing depth（PD）,bleeding index（BI）,keratinized gingiva width（KGW）,residual cement,and bone resorption were recorded.Full mouth periodontal examinations were investigated including PD,BI,and missing teeth.The diagnosis of peri-implantitis and peri-implant mucositis were according to the definition in the consensus report of the Seventh European Workshop on Periodontology.Periodontal status around implants was compared among different implant systems and different loading periods.The associations between PLI,PD,BI,KGW,cement around implant,periodontal status of residual teeth,missing teeth,and peri-implantitis were analyzed by logistic regression.Results：Peri-implant mucositis（bleeding on probing（BOP）and no bone loss）occurred in 81.90%of the subjects and 83.60%of the implants.Peri-implantitis（BOP and bone loss）occurred in 4.50%of the subjects and3.70%of the implants.The prevalence of peri-implantitis showed no significant difference among Straumann,Bicon,3iand Nobel Replace system.The prevalence of peri-implantitis in group loading 0.5-1year and 5-7.5years were significant lower than those in groups loading1-2,2-3,3-4,and 4-5years（P〈0.05）.In the multivariate analysis,missing teeth,mean PD round implant,and mean BI round implant were significant risk indicators for peri-implantitis,after adjusting gender,age,smoking,residual cement,and KGW.Conclusion：The prevelence of peri-implant mucositis was high,the prevelence of peri-implantitis was not increased according to the extension of loading period.It is important to control the probing depth and bleedi
