纤维桩技术在后牙区残冠的修复应用

The Application of Fiber Post Technology in Restoring Residual Crown of Posterior Teeth

目的探讨纤维桩在后牙区残冠修复中的临床应用。方法将114例后牙残冠病例随机分为纤维桩组(实验组)和金属桩核修复组(对照组),随访观察1～2年。结果 实验组根折5例,脱落3例;对照组根折7例,脱落5例,两组无显著性差异。结论纤维桩在后牙区核桩冠修复中固位与金属桩无显著差异,在后牙区残冠修复中具有广阔的应用前景。

Objective To evaluate clinical applications in restoring residual crowns of posterior teeth with fiber posts. Methods 114 residual crowds of posterior teeth were randomly divided into experimental group and control group. Experimental group were treated with fiber posts and control group were treated with casting metal posts respectively. Each group was followed up for 1- 2 years. Re- sults 3 cases were found loosen,together with 5 teeth fractures in experimental group. 5 cases were found loosen, together with 7 teeth fractures in control group. However,there was no significant statistical difference between them. Conclusion There is no significant difference of retention between fiber post and casting metal post. Fiber post presents prospective clinical application in restoring residual crown of posterior teeth.
