摘要
目的探讨玻璃纤维桩和树脂核联合氧化锆全瓷冠在残冠残根修复中的临床效果。方法以玻璃纤维桩和树脂核联合氧化锆全瓷冠修复残冠残根病例48例,共65颗牙(前牙26颗,后牙39颗,其中作为桥基牙的有22颗;残根18颗,残冠47颗)。于修复完成6个月至2年,对全部临床病例进行随访、检查和评估。结果 3颗残根修复后纤维桩脱落,失败率为4.62%,其中2颗经再治疗后有效,另1颗被放弃;其余病例氧化锆全瓷冠保持完整,纤维桩无脱落、折断;X线片示牙根和纤维桩无折断,无牙周和根尖的阴影,牙颈部无继发龋。结论应用玻璃纤维桩树脂核联合氧化锆全瓷冠修复残冠残根,达到了无金属修复的临床要求,是一种较理想的修复方法。
Objective To study the clinical effect of glass fiber post and resin core in combination with a zirconia-ceramic crown in the restoration of residual roots and crowns.Methods Forty-eight patients were enrolled in the study.A total of 65 teeth（26 anterior and 39 posterior with 22 abutment teeth;18 residual roots and 47 residual crowns） were restored with glass fiber post and resin core in combination with a zirconia-ceramic crown.After 6 months to 2 years,all patients were examined and the restoration effect was evaluated.Results In all cases,3 post debondings occurred after the restoration of residual roots（failure rate 4.62%）,in which 2 cases were restored after re-treatment and 1 case was withdrawn.No fracture of zirconia-ceramic crown was observed.No root or post fracture was observed clinically or on radiographs.No apical or periodontal shadow was observed on radiographs,and no secondary dental caries of tooth neck was found.Conclusion The application of glass fiber post in combination with a zirconia-ceramic crown is feasible in metal-free restoration of residual roots and crowns.
