可摘局部义齿预留性设计修复的疗效

Effect of removable partial denture predesigned

目的:评价可摘局部义齿预留性修复设计的修复临床效果。方法:选择40例病例,其中肯氏一类10例、肯氏二类15例、三类10例、四类5例。做保留松动牙的可摘局部义齿预留性修复设计,完成铸造支架可摘局部义齿并嘱正常使用,松动牙拔除后牙列缺损类型向出现亚类和更严重缺损类型转变,将原局部义齿修理后继续使用并定期复查。结果:12个月后复查,38例成功,2例尚可;24个月后复查,38例成功,2例因拔除基牙失败。成功率95%。结论:预留性可摘局部义齿修复设计是临床行之有效的修复方法,设计符合口腔生理,尽管存在一定缺陷,值得临床推广使用。
