摘　　要：目的 分析重度牙周炎老年患者种植修复后种植体边缘骨吸收的相关因素。方法 选取行种植修复的重度牙周炎老年患者195例,随访12个月,统计种植体边缘骨吸收情况,将牙槽嵴吸收高度>0.5 mm的患者纳入吸收组,其余纳入未吸收组;采用Logistic回归模型分析种植体边缘骨吸收的影响因素。结果 40.80%的患者发生种植体边缘骨吸收;Logistic回归分析显示,吸烟(OR=3.080,95%CI 1.494~6.349)、糖尿病(OR=2.542,95%CI1.355~4.769)、缺牙部位为上颌(OR=3.951,95%CI 1.800~8.671)、种植体长轴与牙冠长轴夹角大(OR=2.000,95%CI 1.066~3.752)、种植体周围卫生情况不良(OR=2.573,95%CI 1.435~4.614)是种植体边缘骨吸收不良的危险因素,植入部位骨密质厚度薄(OR=0.214,95%CI 0.086~0.533)则为保护因素,P均<0.05。结论 吸烟、糖尿病、缺牙部位为上颌、种植体长轴与牙冠长轴夹角、种植体周围卫生情况及植入部位骨密质厚度影响重度牙周炎老年患者种植体边缘骨吸收。Objective To analyze the factors related to implant marginal bone resorption after implant restoration in elderly patients with severe periodontitis.Methods One hundred and ninety-five elderly patients with severe periodontitis who underwent implant restoration in Hospital of Stomatology of Jilin University from January 2017 to June 2021 were selected,and the implant marginal bone resorption was recorded after 12 months of follow-up.Patients with alveolar ridge resorption height>0.5 mm were included in the resorption group,and the rest were included in the non-resorption group.The general data of the non-resorption group and the resorption group were compared.The influencing factors of implant marginal bone resorption were analyzed by Logistic regression model.Results After 12 months of follow-up,40.80%of the patients had implant marginal bone resorption.Logistic regression analysis showed that smoking(OR=3.080,95%CI 1.494-6.349),diabetes(OR=2.542,95%CI 1.355-4.769),missing teeth in the upper jaw(OR=3.951,95%CI 1.800-8.671),the angle between the long axis of the implant and the long axis of the crown(OR=2.000,95%CI 1.066-3.752),and poor peri-implant hygiene(OR=2.573,95%CI 1.435-4.614)were risk factors for adverse marginal bone resorption around implants.In contrast,the thickness of the bone quality at the implantation site(OR=0.214,95%CI 0.086-0.533)was a protective factor,with all P<0.05.Conclusion Smoking,diabetes,missing teeth in the upper jaw,the angle between the long axis of the implant and the crown,poor peri-implant hygiene,and the bone quality at the implantation site affected the marginal bone resorption around implants in elderly patients.
