| 选取2007-08～2008-08到该院就诊经纤维桩修复上颌前牙残根残冠患者62例，共78颗患牙；选取同期经金属桩修复上颌前牙残根残冠患者56例，共70颗患牙。患者定期按时随访，对比二者的修复效果。结果 经纤维桩修复的修复体固位和稳定良好，未发现折裂和松动，烤瓷冠边缘密合，牙龈无色素沉着，牙周情况良好，根周无病变。成功78颗，成功率为100.0%。经金属桩修复的上颌前牙残根残冠成功53颗，失败17颗（分别为牙根折3颗，桩核松动脱落2颗，牙龈边缘出现色素沉着12颗），成功率为75.7%，经纤维桩修复上颌前牙残根残冠成功率高于金属桩（χ2=21.40，P<0.01）。结论 纤维桩较金属桩更适合于上颌前牙残根残冠的修复治疗。 |

| Abstract: |
| ［Abstract］ Objective To compare the clinical effects of metal and fiber post and core in restoration of the residual roots and crown of maxillary anterior teeth.Methods Seventy-eight residual teeth of 62 patients repaired with fiber post and core were compared with 70 residual teeth of 56 patients repaired with metal post and core from August 2007 to August 2008.Results Fiber post and core was the best prosthesis in stability，shape，color，soft tissue reaction，marginal adaptation and periodontal health its success rate was 100%.In metal post and core restored group, root fractured was found in three teeth,post and core loosening and falling off in two teeth, and gingival margin coloring in twelve teeth,its success rate was 75.7%.The success rate of the fomer was higher than that of the latter（P<0.01）.Conclusion Fiber post and core were better than metal post and core in repairing the residual roots and crown of maxillary anterior teeth. |
