【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(P0.05)。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(P0.01)。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。
[Abstract]:Objective: to identify the incidence of peri-implant diseases and explore the risk factors of peri-implant disease in China. Methods: the data of 1612 implants in 736 patients after implant repair in the second outpatient department of Peking University Stomatology Hospital were collected. The mean loading time was 22.64 卤0.92 months. The plaque index around the implant, the probing depth, the bleeding index, the width of keratinized gingival, the residual adhesive and the bone resorption were recorded. The incidence of peri-implant inflammation in different implant systems and different reexamination periods were analyzed. Logistic regression analysis was conducted on the risk factors of peri-implant inflammation. Results: at the individual and implant levels, the risk factors of periimplant inflammation were analyzed. The incidence of periimplant mucositis was 81.90%, and the incidence of periimplant inflammation was 4.50% and 3.70.There was no significant difference in the incidence of peri-implant inflammation among different systems, but there was no significant difference in the incidence of peri-implant inflammation between groups 1 to 5 years after restoration. The incidence rate of 0.5 ~ 1 year and 5 ~ 7 years after restoration was significantly lower than that in 1 ~ 5 years group (P 0.05). Logistic regression analysis showed that after adjusting for sex, age, smoking, adhesive and keratinizing gingival width, the number of teeth missing in the mouth was lower than that in the control group. Conclusion: the incidence of periimplant mucositis is widespread, and the incidence of periimplant inflammation does not increase with the prolongation of repair time. The key to prevent periimplant inflammation is to control the depth of exploration and bleeding around implants.
