摘要

目的 :对比隐形义齿（弹性义齿）以及传统可摘局部义齿不同固位体———弹性塑胶卡环、锻丝卡环

铸造卡环———对患者基牙牙周的影响

观察隐形义齿固位体是否会对基牙牙周健康造成不良影响。方法 :收集 2 5 5例临床单颗第一磨牙缺失的患者

分别采用胶链可摘局部义齿、铸造支架可摘局部义齿、隐形义齿修复。测定修复后 1个月及 1年基牙牙周健康变化。结果 :戴用隐形义齿与其他两类金属卡环

长时期后

基牙牙菌斑指数、牙龈指数、牙齿松动度、牙周袋深度、牙槽骨高度无显著性差异。结论 :隐形义齿修复局部牙列缺损相对于传统可摘局部义齿对基牙牙周健康无明显不良影响

是一种良好的临床修复体

Abstract

Objective:To compare the effects on periodontal health of the abutment between concealed denture(flexible denture)and two traditional removable partial dentrue(RPD)-one with flexible retainers

the other with wire clasps and casting clasps

and observe whether the concealed denture can damage the abutment teeth.Methods:255 cases of the patients losing one of the first molar were collected

and divided into three groups

using one of three kinds of RPD and then repaired with the concealed denture

traditional plastic denture and casting frame denture respectively to one group.The indices of periodontal health of the abutment teeth were examined after 1 month and 1year.Results:Among three groups

the plaque index(PLI)

gingival index(GI)

probing depth(PD)

teeth mobility and alveolar bone height of the abutment teeth were similar.Conclusion:Compared with two traditional RPD designs

there are no negative effects on periodontal health of the abutment teeth with the concealed denture long-term.
