摘　　要：目的探讨分割式可摘局部义齿的制作方法和临床应用效果。方法分割式可摘局部义齿由双层基托组成,下层基托与口腔牙槽嵴、黏膜紧密接触,附有义齿,起承力作用:上层基托设计卡环,起固位、卡抱作用, 维持义齿的稳定。选择15例Kenney Ⅲ类患者采用该方法进行义齿修复,3年后复查,观察基牙松动情况,并通过问卷调查了解患者对义齿的咬合情况、固位稳定性和舒适度的满意率。结果 15例患者的56颗基牙中,38颗正常, 18颗Ⅰ°-Ⅱ°松动。3年后正常基牙存留率为100％,松动基牙存留率为83．3％。3年后15例患者对义齿的咬合情况、固位稳定性和舒适度的满意率分别为73％、60％和73％。结论分割式可摘局部义齿能较好地满足患者对美观和咀嚼功能的要求,并对松动基牙的影响不大,适用于口腔状况欠佳或基牙有Ⅰ°-Ⅱ°松动的患者。Objective This report is to introduce the processing method of the separate movable partial demure and get an initial clinical evaluation.
