摘要：

目的    比较纤维桩和金属桩的临床效果。方法    选取2008年3—6月河南省人民医院口腔科进行桩核冠修复的患者63例（共70颗患牙），随机将70颗患牙分为2组，每组35颗。试验组采用纤维桩+树脂核联合烤瓷冠修复；对照组采用铸造钴铬金属桩核联合烤瓷冠修复。修复后随访观察2年，并评价临床效果。结果    修复1年后，试验组1例患牙在去除临时冠时纤维桩核脱落，经重新黏结后未发生再脱位，成功率97.1%；对照组1例牙龈缘充血，1例根尖周炎，成功率94.2%，组间差异无统计学意义（χ2 = 0.348，P = 0.555）。修复2年后，试验组成功34颗，成功率97.1%；对照组成功31颗，失败4颗，其中根折、根尖周炎、桩核脱落、牙龈缘充血各1颗，成功率88.6%，组间差异无统计学意义（χ2 = 1.938，P = 0.164）。结论    纤维桩可替代金属桩，常规应用于临床。

Abstract:

Objective    To compare the clinical effects of fiber post-retained and metal post-retained restorations. Methods    Seventy endodontally treated teeth were divided into 2 groups randomly and each group consisted of 35 teeth. One group teeth were restored with fiber post-resin core and porcelain crown and the other group were treated with cast metal-core and porcelain crown. The teeth were clinically examined regularly for 2 years. The data were analysed with Chi-square method. Results    One fiber post dislocated when provisional crown was removed in 1 year after restoration and the success rate was 97.1%. One gingival inflammation case and one periapical inflammation case occurred among the metal post group in 1 year after restoration. There was no statistical significance between the two groups（χ2 = 0.348，P = 0.555）. Two years after restoration，the success rate was 97.1%. Four teeth （one root fracture ，one periapical inflammation， one post dislocation ， one gingival inflammation） of metal post group failed and the success rate was 88.6%. There was no statistical significance between the two groups（χ2 = 1.938，P = 0.164）. Conclusion    Fiber post -retained restoration can be routinely used clinically instead of metal post-retained restoration.
