Three removable partial denture designs were investigated to determine the effect of minor connector configuration on the periodontal health of abutment teeth. Twenty-five patients wore three different removable partial dentures for 19 weeks each. The first removable partial denture placed a tilting force on the abutment teeth; the second was stress-releasing; and the third collected the least amount of plaque. Plaque accumulation, the condition of the periodontium, migration of the abutment teeth, deformation of the clasp arms, retention of the prosthesis, and patient preferences were assessed. The results demonstrated that the partial denture retentive design did not affect plaque formation. The prosthesis designed to place a tilting force on the abutment teeth appeared to cause the least mobility and migration of the abutments and had the greatest acceptance by the patients.
研究了三种可摘局部义齿设计，以确定小连接体构型对基牙牙周健康的影响。25名患者分别佩戴三种不同的可摘局部义齿，每种佩戴19周。第一种可摘局部义齿对基牙施加倾斜力；第二种具有应力释放功能；第三种收集的牙菌斑量最少。评估了牙菌斑堆积、牙周状况、基牙移位、卡环臂变形、义齿固位情况以及患者偏好。结果表明，局部义齿固位设计不影响牙菌斑形成。设计为对基牙施加倾斜力的义齿似乎导致基牙的移动性和移位最小，并且患者的接受度最高。
