玻璃纤维桩联合双固化树脂水门汀修复前牙残根残冠

Restoration of residual root and crown by glassfiber post and self-adhesive universal resin cement

目的:评价玻璃纤维桩联合双固化树脂水门汀(RelyXunicem)修复前牙残根残冠的临床效果。方法:选择80颗已行根管治疗的前牙残根残冠,利用双固化树脂水门汀将Fibra-post玻璃纤维桩粘结于根管内,再在纤维桩上用复合树脂堆核,最后全冠修复。治疗完成后6、12个月复诊,观察临床效果。结果:6个月后复查,成功率为100%。12个月时,成功率98.7%,3颗患牙失访,1颗残根的纤维桩折断,其余76颗患牙无不适,桩核冠稳固无松动,均修复成功。结论:玻璃纤维桩联合双固化树脂水门汀修复残根残冠疗效好,可满足临床需要。

Objective To evaluate the effects of glassfiber Post and self-adhesive universal resin cement in restoration of residual root and crown on anterior teeth. Methods 80 residual roots and crowns after endodontically treatment were selected.Glassfilber post and self-adhesive universal resin cement combinated to fabricate post,and then restored with full crown.patients were followed up in 6 months and 12 months after treatments. Results After observation for 6 months.the success rate of 80 restorations reached 100%.After 6 months. the success rate reached 98.7%.3 teeth failed to visit.One broken post was found,restorations of the rest 76 teeth were firm and no dentine fracture was found in all restored teeth. Conclusion Glassfiber post and self-adhesive universal resin cement were be considered as good material to restore residual root and crown of anterior teeth.
