摘　　要：目的分析影响再植牙愈合的相关因素,为提高纵折后牙粘结再植的疗效提供依据。方法对109颗纵折后牙行粘结再植术,随访3个月作临床评估及牙周愈合评估,对不同离体时间与愈合方式作统计学分析。结果牙周愈合状况评估成功89颗、失败20颗,成功比为81.65%。其中牙周膜愈合44.9%,骨性愈合36.7%。结论后牙纵折粘结再植术中离体时间的长短对再植牙术后愈合方式影响不明显。Objective To investigate the relationship between dislocation time and prognosis in vertical fractured posterior teeth replantation. Methods A total 109 vertical fractured posterior teeth were extracted, treated with root canal therapy and spliced in vitro, and were replanted. The patients were followed up for 3 months and the prognosis was evaluated by clinical and radiological examination. Statistical analysis were performed for e- valuating the prognosis in different dislocation periods and curing ways. Results 89 cases of 109 teeth were per- formed successfully. The total success rate was 81.6%, during which periodontal ligament healing was 44.9% and osseointegration healing was 36.7%. Conclusions There was no correlation between dislocation time and prognosis in vertical fractured posterior teeth replantation.
