目的：研究不同的义齿设计与末端游离缺牙的牙槽骨吸收的关系．方法：选择末端游离缺牙的患者76例，其中采用RPI型卡环18例，RPA型20例，传统三臂卡环15，冠外附着体23例．义齿修复前以及修复后12个月拍摄基牙及远中牙槽骨定位X线片，计算剩余牙槽嵴的骨吸收量．结果：末端基牙远中牙槽骨的吸收：冠外附着体组吸收量最低，RPA组和RPI组低于传统三臂卡环组．结论：近中牙合支托设计的卡环，较远中牙合支托设计的卡环，更利于维护末端基牙远中牙槽骨的健康；冠外附着体更有利于保护基牙．

Objective： To study alveolar bone resorption relationship in different dentures designs for distal extension, method： 76 patients treated With distal extension removable partial dentures were selected of whom 18 patients were treated with RPI clasp assemblies, and 20 with RPA clasp assemblies. 15 with conventional circumferential clasp assemblies, 23 with outside attachments. The identical radiographs were obtained for each patient affter 12 months. Results： the resorption of the reSidual ridge for the outside at- tachments group was lowest, and the RPI and RPA groups were lower than that of the conventional circumferential clasp group. Conclusion： Mesial occlusal rests is more favorable for the distal alveoli health than distal occiusal rests ,and outside attachments are most favorable for the distal alveoli health.
