纤维桩核冠修复牙体严重缺损的临床效果观察

Clinical results of large defect teeth or flared roots restored by fiber posts and resin composites core in combination with full crowns

目的观察纤维桩树脂核全冠修复牙体严重缺损和薄弱根管的临床修复效果。方法选择牙体大面积缺损和薄弱根管患者165例219个患牙为研究对象。患牙经根管治疗后行纤维桩树脂核全冠修复,修复完成后6个月、1年、2年进行临床复查,其中牙体缺损达龈下行牙龈切除术或冠延长术的患牙,增加修复后1个月和3个月临床复查,评价其临床修复效果。结果 165例的219个患牙中,有4例出现纤维桩与根管壁完整脱落,均未见根折、根裂,重新粘固后未见异常。其余215个患牙修复体未出现脱落,冠边缘密合,牙周正常,219个患牙均未出现基牙松动。结论应用纤维桩树脂核全冠修复牙体严重缺损和薄弱根管可以达到满意的临床修复效果。

Objective To observe the clinical results of fiber post and resin composite core for the repair of large defect teeth or flared roots. Methods A total of 219 large defect teeth or flared roots from 165 patients were restored by fiber posts and resin composite core as well as full crowns. The clinical results of the restorations were followed up for a minimum of six months. Results Four of the 219 restorations failed but the roots remained intact and re-bonded with the previous post-and-core crowns. The restorations and periodontal tissues of the other 215 teeth were normal and successful. Conclusion Fiber post and resin composite core system is reliable for restoring large defect teeth or flared roots with satisfactory clinical results.
