摘　　要：目的:观察套筒冠固位式固定桥基牙的牙周变化情况,探索该修复方法对于牙周维护的作用。方法:选择符合入选标准的患者22例,随机分为两组,即拆卸组和对照组,所选患者均为下颌第一磨牙缺失,每位患者均以下颌第二双尖牙和下颌第二磨牙为基牙,在修复后即刻以及修复后3、6、9个月,对基牙四个面——近中面、远中面、颊面、舌面进行牙龈指数和龈沟出血指数的检测,利用SPSS12.0统计软件对检测数据进行分析,评定基牙不同时间段及不同部位的牙周状况。结果:全部入选患者按照要求完成了基牙制作和戴用,并完成了相关的检测。统计分析显示拆卸组近远中面牙周指数与对照组相比,有显著差异,有统计学意义(P<0.05)。而拆卸组颊舌面牙周指数与对照组相比,无显著差异,无统计学意义(P>0.05)。结论:套筒冠固位式固定桥便于拆卸,有利于基牙牙周的定期卫生维护。Objective:To research and assess abutment periodontal condition of telescope retained fixed bridge.Methods: 22 cases of the first molar defect were restored by telescope retained fixed bridge, then, they were randomly divided into removable group and control group. Gingival index and gingival sulcus bleeding of the abutments were tested immediately when the denture were restored and in 3, 6, 9 months respectively. Results: At three stages (after 3, 6, 9 months since restoration), the periodontal index in co...
