目的：比较玻璃纤维桩和铸造金属桩2种桩核修复方法的临床效果。方法收集经过根管治疗的上前牙残根残冠379例，共578个患牙。随机分为2组，观察组190例，共292颗，采用玻璃纤维桩加卡瑞斯玛树脂恢复桩核；对照组189例，共286颗，采用铸造金属桩核。对比2种修复方法的效果。结果经过2年的随访观察，玻璃纤维桩组成功率96.7%，铸造金属桩核组成功率84.1%。结论玻璃纤维桩美学效果好，在防止根折、龈缘着色等方面优于铸造金属桩，值得临床推广运用。

Abstract: [Objective] To compare the clinical effect of glass fiber post and metal post in post core restoration. [Method] 379 cases received root canal treatment for residual root and crown of anterior teeth a total of 578 teeth, were randomly divided into 2 groups. The observation group of 190 cases, a total of 292 teeth were treated with glass fiber post and resin core Jaka Reiss Mar recovery. 189 cases in the control group, a total of 286 teeth, were treated with cast metal post and core. The repair effect of these two kinds of method was repaired.. [Result] After 2 years observation, the success rate of glass fiber post group was 96.7%, and the success rate of the cast metal post and core group was 84.1%. [Conclusion] The effect of glass fiber post aesthetics is superior to cast metal post in preventing root fracture and gingival coloration. It is worthy of clinical application.

残根残冠在临床上一般采用桩冠修复。由于玻璃纤维桩良好的生物相容性、抗腐蚀性等优点，尤其重要的是其弹性模量与牙本质接近，能有效缓解牙本质的应力集中，而逐渐被应用于临床。本文对379例患者的上前牙残冠残根，分别采用玻璃纤维桩和铸造金属桩核2种桩核修复方法，并通过定期的随访观察，分析评价玻璃纤维桩在上前牙残冠残根修复中的临床效果。
