弹性义齿和传统可摘义齿修复肯氏Ⅲ类磨牙缺损的临床效果比较

Comparison of the clinical effect of between flexible dentures and removable partial denture in the repair of the kennedy class Ⅲ Dentition defect

目的:对临床中肯氏Ⅲ类磨牙缺损采用弹性义齿与传统可摘义齿两种修复方式的临床疗效进行比较。方法:选取肯氏Ⅲ类磨牙缺损的患者98例,按修复方式不同将其分为弹性义齿组和传统可摘义齿组,对两种修复方式下的临床效果和患者满意度进行比较。结果:对于肯氏Ⅲ类磨牙缺损的患者,弹性义齿组在稳定性、舒适度、美观性、食物嵌塞等方面优于传统可摘义齿组,在对软组织压迫、咀嚼效率等方面两组义齿修复并未出现明显差异,但随着佩戴时间的延长,传统可摘义齿固位性逐渐优于弹性义齿,弹性义齿佩戴半年后基托材料逐渐出现变色与老化的现象,两组比较均有统计学差异(P<0.05)。结论:弹性义齿在肯氏Ⅲ类磨牙缺损的义齿修复中有其独特的优势,在临床上可以根据其特性在适合患者中推广使用,远期效果仍需要继续观察。

Objective：To compare the clinical effect of two methods of repair of Kennedy class Ⅲ Dentition defect.Methods：98 patients with Kennedy Class III Dentition defect were divided into flexible denture group and traditional removable denture group according to different repair methods.The clinical effect and patient satisfaction were compared.Results：The flexible denture repair is superior to the traditional RPD group in stability,comfort index,beauty and food impaction.They were no significant differences in soft tissue compression and chewing efficiency.However,traditional RPD group gradually better than the flexible denture in the part of retention with the extension of time.They gradually appear discolour and aging phenomenon after wearing the flexible denture for half a year.The two groups were statistically significant（P〈0.05）.Conclusion：The flexible denture has unique advantages in denture restoration of Kennedy class ⅢDentition defect,it can be widely used in clinic,but long-term effects need to be observed.
