3种纤维桩修复残冠的临床观察

目的:探讨临床常用的3种玻璃纤维桩在残根残冠修复治疗中的临床效果。方法:148例患者共计161颗残根残冠经完善的根管治疗后采用玻璃纤维桩堆塑树脂核行全冠修复,观察其疗效。结果:经过2年的临床观察,纤维桩核修复成功率为91.93%,10例失败源于桩或冠松脱,其中FibraPost玻璃纤维桩桩核松脱率最低。3例失败表现为桩核折断。结论:纤维桩树脂核可作为理想的残根残冠修复方式,纤维桩表面固位设计以及纤维桩与根管的密合度都可以增强其抗脱位能力。

The Clinical Evaluation of three kinds of Glassfiber Post in Restoration

Objective: To evaluate the effects of three kinds of glassfiber post and composite resin core in restoration of residual root and crown.Method: 148 patients with 161 residual roots and crowns after endodontically treatment were selected.Glassilber post and related bonding resin was performed to fabricate post,then restored with crowns.All patients were followed up after treatments.Results: 2 years later,10 cases failed due to the fall off of the post or crown,3 cases failed due to the broken of the post,and the failure at of the FibroPost was the lowest among the three kinds of posts.Conclusion: Glassfiber post and composite resin core can be considered as good material to restore residual root and crown due to its high-strength,aesthetics and convenience for operation.The design of the post surface is a factor to enhance the bonding strength.
