ERA附着体全口覆盖义齿修复效果研究

Clinical Application Study of ERA Overdentures

目的:通过随机对照实验(Randomized Controlled Trail RCT)比较ERA附着体全口覆盖义齿与传统全口覆盖义齿的临床修复效果.方法:采用随机、单盲(患者)、平行对照试验设计,试验组为ERA附着体全口覆盖义齿组,对照组为传统全口覆盖义齿组,治疗前及治疗后6个月均要求患者填写口腔健康影响程度量表(OralHealth Impact Profile-14 OHIP-14中文版).结果:共入选患者78例,可评价疗效病例77例,试验组38例,对照组39例.在一般资料中,试验组与对照组治疗前口腔健康质量状况差异无统计学意(P>0.05).试验组和对照组治疗后口腔健康质量状况均有很大改善,两组改善程度比较没有统计学意义(P>0.05).结论:ERA附着体全口覆盖义齿和传统全口覆盖义齿均能很大程度的改善患者的口腔健康状况,当口腔内多数牙齿缺失,余留牙齿不足4颗残根或者残冠,牙周组织基本健康时,可选择ERA附着体全口覆盖义齿.

Objective： To compare the effect of clinical application of ERA overdentures and conventional overdentures in a randomized controlled trial. Method. Following randomization , Suitable patients were randomly allocated by gender and operator assignment to two experimental groups, designated the ERA Group and the Conventional Denture Group Patients completed the Oral Health Impact Profile （OHIP-- 14）pre--treatment and six months post--treatment. Results： Upon completion of treatment, both groups reported improvement in oral--health--related quality of life. There were no significant post--treatment differences between the groups（P〉0.05） Conclusion： Following completion of treatment, substantial improvements in oral--health--related quality of life and denture satisfaction were reported by both groups. However, there were no significant post--treatment differences between the groups.
