Objective To investigate the clinical effect of immediate fiber post-core restorations for anteri-or residual roots and crowns after root canal therapy(RCT)with hot gutta-percha points,which provided theoretical basis for anterior residual roots and crowns restoration.Methods 21 7 anterior residual root and crown teeth were treated with hot gutta-percha points for RCT.Then,they were randomly divided into Group A with 1 1 5 teeth for immediate pre-made fiber post-core crowns restorations,and Group B with 1 02 teeth for fiber post-core crowns restorations 1 week after the RCT.All the teeth were followed for 3 years.Results Af-ter 3 year’s follow-up,5 teeth in Group A were missing,3 fiber post-core lost,and 1 with periapical periodon-titis,and the success rate was 96.36%.There were 1 teeth in Group B with periodontitis,2 fiber post-core lost,4 with periapical periodontitis,and the success rate was 93.1 4%.There was no statistical significance (P>0.05).Conclusion It is feasible to make immediate pre-made fiber post-core crowns restorations for ante-rior residual roots and crowns after completing RCT.%目的：观察前牙残根残冠热牙胶根管充填后即刻行纤维桩核冠修复的临床效果，为桩核冠修复时机的选择提供临床依据。方法选取217颗前牙残根残冠，用热牙胶加AH Plus糊剂垂直加压根充完毕后，随机分为两组。A组115颗患牙即刻行预成纤维桩核冠修复，B组102颗患牙1周后行纤维桩核冠修复。进行3年的随访，观察临床修复效果。结果 A组5颗患牙（2名患者）失查，3颗纤维桩脱落，1颗出现根尖病变，修复成功率为96．36％；B组1颗出现牙周病变，2颗纤维桩脱落，4颗出现根尖病变，修复成功率为93．14％，两组临床疗效差异无统计学意义（P＞0．05）。结论完善的根管充填后即刻桩核冠修复是可行的，值得临床推广。
