目的：评价纤维桩联合复合树脂修复前磨牙重度楔状缺损的美学效果和临床疗效。方法：选择96例患者的128颗穿髓型楔状缺损的前磨牙，64颗采用玻璃纤维桩联合复合树脂修复，64颗采用采用简单树脂核充填法修复。统计修复后即时及1年后的美学效果，及修复后1年的临床疗效。结果：在美学效果评价方面,两组的美学效果在修复后即时比较，差异无统计学意义(P＞0.05)；而修复后1年则前者优于后者，差异有统计学意义(P＜0.05)。在临床疗效上玻璃纤维桩联合复合树脂修复明显优于简单树脂核修复，差异有统计学意义(P＜0.01)。结论：玻璃纤维桩联合复合树脂修复穿髓型楔状缺损患牙，具有良好的美学效果和临床疗效。%Objective To evaluate the aesthetics and clinical effect of severe wedge-shaped defect of premolar restored with fiber post-core combined with composite resin. Methods 128 teeth in 96 cases with severe wedge-shaped defects were randomly divided into two groups.64 teeth were restored with fiber post-core combined with light-cured composite resin and the other 64 teeth restored by only composite resin.Evaluation of aesthetic effect was made immediately and 1 year later respectively.Evaluation of clinical effect was made after restoration for 1 year. Results Aesthetic effects were no significant difference between the two groups on immediate postoperative(P>0.05), and 1 year later the former was better than the latter(P<0.05).The clinical efficacy on the glass-fiber post restored was significantly better than the simple composite resin core repaired(P<0.01). Conclusion The aesthetics and clinical effect of severe wedge-shaped defect of premolar restored by fiber post-core combined with composite resin is preferable.
