摘要
目的:探讨玻璃纤维桩和铸造桩核全冠修复磨牙残冠、残根的临床效果。方法:选择经过完善根管治疗的磨牙残冠215例,采用双根管桩设计,分别用玻璃纤维桩和铸造桩核进行全冠修复,临床随访观察4年。结果:玻璃纤维桩核组失败率2.73%,明显低于铸造核组(14.29%),具有统计学意义。结论:在磨牙残冠的全冠修复中,玻璃纤维桩核疗效较好。
Objective The aim of prospective randomized controlled trial to evaluate the clinical effect of glass fiber-reinforced post core and casting-post-core system applied in the restoration of molar residual crown and root.Methods 215 molar residual crowns restored by spiral-post combined with glass fiber-reinforced post core and casting-post-core respectively and united with full crown werer observed for 4 year.Results The failure ratio of class fiber-reinforced post core group（2.73%）was less than that of the casting-post-core group（14.29%）.There was statistical difference on the failure.Conclusion On the restoring of the molar residual crown,the class fiber-reinforced post core group shows the better clinic effect than the cssting-post-core system.
