摘要/Abstract

摘要： 目的　比较纤维桩、纤维桩氧化锆全瓷冠、直接树脂充填修复根管治疗后的第一前磨牙重度楔状缺损的临床疗效。方法　选择97例患者的135颗根管治疗后的第一前磨牙，随机分为3组：纤维桩修复组、纤维桩全瓷冠修复组和复合树脂修复组，分别使用纤维桩联合光固化复合树脂充填法、纤维桩氧化锆全瓷冠修复法和光固化复合树脂直接充填法进行修复。观察24个月，比较不同组别之间成功率和性价比满意度的差别。结果　24个月观察期结束时，纤维桩修复组成功率为95.6%；纤维桩全瓷冠修复成功率93.3%；复合树脂修复组成功率为82.2%。纤维桩修复组与纤维桩全瓷冠修复组成功率的差异无统计学意义（P>0.05）；纤维桩修复组与复合树脂修复组成功率的差异有统计学意义（P<0.05）。纤维桩修复组患者的性价比满意度最高。结论　纤维桩修复组和纤维桩全瓷冠修复前磨牙临床效果基本相同，采用纤维桩联合光固化复合树脂修复重度楔状缺损的前磨牙是比较可靠的方法。

Abstract: Objective　To compare the clinical effects of fiber post, fiber-post zirconia + all-ceramic crown and direct resin filling restoration on endodontically treated premolars with severe wedge-shaped defects. Methods　Ninety-seven patients with 135 endodontically treated premolars with severe wedge-shaped defects were randomly divided into three groups. After repairing them with the three methods, the success rate and the performance satisfaction of the different groups were observed in 24 months. Results　At the final follow-up, the success rate of the group which was restored by fiber posts was 95.6%, the success rate and performance satisfaction of the group by fiber-post zirconia + all-ceramic crown was 93.3% and the success rate and performance satisfaction of the third group by composite resin was 82.2%. There was no statistically significant difference in the success rate between the fiber post group and the fiber-post zirconia + all-ceramic crown group (P>0.05), while the statistical difference of the success rate between the fiber post group and the composite resin group was significant (P<0.05). The satisfaction rate of fiber-post zirconia + all-ceramic crown group was the highest. Conclusions　As far as the observation is concerned, the clinical effects of the fiber post and the fiber-post zirconia + all-ceramic crown group are basically the same, and fiber post is a relatively reliable method to restore endodontically treated premolars with severe wedge-shaped defects.

Key words: fiber post, zirconia all-ceramic crown, composite resin, wedge-shaped defects
