    【摘要】目的 分析重度牙周炎老年患者種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% CI 1.355～4.769)、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0.5 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 ......
