目的观察纤维桩树脂核用于残根、残冠牙齿的修复效果。方法选取82颗残根残冠患牙,其中前牙40颗,后牙42颗,经过系统完善的根管治疗后,用双固化树脂将玻璃纤维桩粘结在根管内,然后形成树脂核,用全冠进行修复。结果随访24个月,82颗牙中5,颗患牙失访,12个月时,1个桩折断,1个冠松动脱落,其余75颗牙无异常,至24个月时无变化,成功率为97.4%。结论纤维桩树脂核是残冠残根保存修复的理想材料。
Objective To observe the repairing effect of fiber post resin core on residual teeth and residual crown teeth. Methods Totally 82 residual root crowns were selected, including 40 anterior teeth and 42 posterior teeth. After well-designed root canal treatment, the double-cured resin was used to bond the glass fiber posts in the root canal, and then the resin core , With a full crown to repair.
