玻璃纤维桩在前牙残冠修复中的应用

目的探讨纤维桩在前牙残冠修复中的临床应用价值。方法将147例病人160颗前牙残冠残根随机分为纤维桩（A组）和金属铸造桩核修复组（B组）,每组80颗牙,随访观察2年。结果A组78例桩冠修复体完好,成功率为97.5%,B组72个桩冠修复体良好,成功率为90.0%。两组相比纤维桩修复组较金属铸造桩核组治疗成功率高（P〈0.05）。结论 用预成的根管玻璃纤维桩系统进行前牙残冠修复,具有操作简单、方便、减少根折,缩短就诊次数等优点。

Application of fiber post system in restoring residual crown of anterior teeth

Objective To evaluate clinic application value of restoring residual crowns of anterior teeth with fiber posts.Methods 147 patients with 160 residual crowns of anterior teeth were randomly divided into group A（80 teeth） and group B（80 teeth）,group A were treated with fiber posts and group B were treated with casting metal posts respectively.Each group was followed up for 2 years.Results Dental prosthetic restorations of post crowns in 78 cases of fiber posts of group A were completed with a successful rate of 97.5%,while 72 cases with casting metal posts in group B had a successful rate was 90.0%.Compared the results of two groups,the successful rate was higher in fiber post system repair group than that in casting post and core group（P0.05）.Conclusion The application of fiber post to repair residual crown of anterior teeth is simple,convenient and can reduce the root fracture,which may increase the possibility for making teeth again and reduce the number of seeking treatments.
