1、非金属桩核系统修复后牙残根残冠的临床观察非金属桩核系统修复后牙残根残冠的临床观察[摘要]目的:探讨纤维桩核系统与氧化错陶瓷桩核系统在治疗后牙残根残冠方而的临床效果,评价非金属桩核系统修复后牙残根残冠的治疗情况。方法:选择94例患者102颗后牙残根残冠,经完善根管治疗后,54颗采用纤维桩核系统修复,48颗采用氧化错陶瓷桩核系统修复。随访2〜3年后对结果进行评价。结果:本组94例(102颗患牙),纤维桩核系统修复成功率为90.7%,氧化钳陶瓷桩核系统修复成功率为89.6%o两种桩核冠修复方法在临床效果上无统计学差异(x2检验:卩>0・01)o结论:纤维桩核系统与
2、氧化错陶瓷桩核系统在修复后牙残根残冠方面无明显区别,均能满足临床要求。[关键词]非金属桩核系统;后牙残冠残根;临床观察[中图分类号1R783[文献标识码]A[文章编号]1008-6455(2010)08-1190-03ClinicalobservationsaboutthemanagementoftreatingposteriorresidualrootandcrownwithNon-metallicpostandcoresystemsWANGSheng-zhou1,ZHAOLu2,ZHIKe-qian2,SHIMing-juan3(1.Hea1thCent
