摘要
目的比较在纤维桩修复中,自酸蚀粘接系统和自粘接桩核树脂水门汀临床修复效果。方法选取100例患者220颗需要桩核冠修复的前磨牙或前牙,随机分为2组,分别采用玻璃纤维桩+自粘接桩核树脂水门汀修复方案和玻璃纤维桩+自酸蚀粘接系统+桩核树脂修复方案,2组患牙均用烤瓷熔附金属全冠或全瓷冠修复牙体外形。36个月后复查,统计2组修复的成功率,并用χ2检验。结果自粘接组有103颗牙(46例)得到评价,无桩核脱落,无纤维桩折断、牙根折裂,桩核修复成功率100%;自酸蚀粘接组有98颗牙(48例)得到评价,桩核脱落1颗,未发生纤维桩折断、牙根折裂,桩核修复成功率98.99%,两者差别无统计学意义。结论在玻璃纤维桩桩核修复中,采用自粘接桩核树脂水门汀和自酸蚀粘接系统+桩核树脂均能取得良好的临床效果。
Objective The aim of this study was to compare the clinical performance of glass-fiber posts in combination with either self-adhesive resin cements or self-etch adhesives over up to 3 years in restoration of teeth.Methods 220 premolar teeth and anterior teeth（from 100 cases） that needed post-core crown restoration were allocated into 2 groups randomly.Group A were restored with glass fiber posts in combination with self-adhesive resin cements.Group B were restored with glass fiber posts in combination with self-etch adhesives.Two groups were restored with porcelain fused metal crowns or full-ceramic crowns.The success rates of two groups were observed 36 months later.The data was statistically analyzed by χ^2 test.Results 103 teeth（from 46 cases） in group A and 98 teeth（from 48 cases） in group B were evaluated after 36 months.There was no fiber post fracture,root fracture,and post debonding in group A.Its success rate was 100%.There was one post debonding and no root fracture or fiber post fracture in group B.Its success rate was 98.99%.The difference in the success rates between two groups was not statistically significant.Conclusions In fiber post-core restoration,clinical performance of glass-fiber posts in combination with either self-adhesive resin cements or self-etch adhesives was favorable.
