年轻恒牙完全脱位再植术61例临床疗效分析

目的 分析外伤后完全脱位的年轻恒牙再植术的临床疗效及影响因素。方法 选取2015～2018年我科治疗的61例73颗年轻恒牙外伤脱位患者为研究对象,回顾性分析其再植术后的临床疗效。结果 73颗完全脱位牙再植术后,经过1～3年临床观察,治疗效果:优57颗,良6颗,差10颗,再植成功率为86.3%,总体治疗效果较理想。其中伤后15 min～1 h和1 h～24 h进行再植的治疗效果明显好于伤后24 h以上再植的患牙;伤后15 min～1 h再植的治疗效果最佳。结论 再植术是治疗年轻恒牙外伤全脱位的有效方法,再植术成功的关键是尽量保持离体牙牙周膜的活性、正确保存脱位牙并及时再植。脱位后15 min～1 h的再植效果最佳。

Analysis on the clinical efficacy of 61 cases of replantation for complete dislocation of young permanent teeth

Objective To analyze the clinical efficacy and influencing factors of replantation of young permanent teeth after complete traumatic dislocation.Methods Clinical observation and retrospective analysis were performed on 61 cases of 73 young permanent teeth with traumatic dislocation received by our department from 2015 to 2018 after replantation.Results After replantation of 73 completely dislocated teeth,clinical observation was conducted for 1 to 3 years,and the therapeutic effects were as follows:57 excellent teeth,6 good teeth and 10 poor teeth,the success rate of replantation was 86.3%,and the overall therapeutic effect was ideal.Among which,the therapeutic effect of replantation from 15 min to 1 h and 1 h to 24 h after injury was significantly better than the replantation over 24 h after injury;the therapeutic effect of replantation from 15 min to 1 h after injury was the best.Conclusion Replantation is an effective method for treating the complete traumatic dislocation of young permanent teeth; the key to the success of replantation is to keep the activity of the periodontal membrane in vitro as far as possible,preserve the dislocated teeth correctly and replant them in time.The best replantation effect is 15 min to 1 h after dislocation.
