The survival rate of 2094 abutment teeth in 671 removable partial denture cases was analysed. Within an interval of 2-7 years 150 abutments were lost. The survival-rate of abutments in severely reduced dentitions differs significantly from that in dentitions with more than 3 teeth. Regarding the framework design there was no significant difference in the survival-rate of abutment teeth for removable partial dentures supported by more than 3 teeth.
分析了671例可摘局部义齿病例中2094颗基牙的存活率。在2至7年的时间间隔内，有150颗基牙缺失。严重牙列缺损时基牙的存活率与牙齿数量多于3颗时的牙列情况有显著差异。关于支架设计，由3颗以上牙齿支持的可摘局部义齿，其基牙的存活率没有显著差异。
