桩核树脂一步法成形纤维桩核修复牙体缺损69颗临床分析

目的观察桩核树脂（PULPDENTEmbraceCoreResinCement）一步法成形纤维桩核在牙体缺损修复治疗中的临床应用效果。方法61例牙体缺损患者，共76颗患牙，经完善根管治疗后．采用美国TENAX纤维桩及PULPDENTEmbraceCoreResinCement桩核树脂形成纤维桩树脂核，恢复基牙外形并进行全冠修复。随访1-2年，观察临床应用效果。结果3例患者失访，其余58例患者随访平均1．6年。69颗患牙中，治疗成功62颗．失败7颗，成功率为89．86％。7颗均为修复后0．5～1年出现纤维桩的松动、脱落，没有根折、桩折现象发生。结论应用PULPDENTEmbraceCoreResinCement桩核树脂，一步法形成纤维桩树脂核修复技术是一种快捷、可靠、有效的修复牙体缺损的方法，是纤维桩核应用的趋势。

Clinical application of one-step conformation of glass fiber post core with PULPDENT embrace core resin cement in the restoration of 69 teeth de- fects

Objective To observe the clinical effect of one-step conformation of glass fiber post core with PULPDENT embrace core resin cement in the restoration of teeth defects. Methods A total of 61 patients with 76 teeth defects af- ter root canal therapy were instrumented by American fiber post and PULPDENT embrace core resin cement to restore denture shape and all-ceramic crowns. After followed up for 1 to 2 years, we observed the clinical effect. Results Three cases were missing follow-up, and in the other 58 cases with 69 teeth defects, 62 teeth got successful treatment, but 7 failed. The reason of failure was the glass fiber posts loss after 0.5 tol years restoration. No root or post broken were found. The success rate was 89.86%. Conclusion One-step conformation of glass fiber post core with PULP- DENT embrace core resin cement is a simple ,reliable and effective way in the restoration of teeth defects.
