摘　　要：牙全脱出是牙外伤中最为严重的一种类型,目前脱位牙的首选治疗方法是牙再植。临床上多数情况下,患者及其家属未能正确地保存脱位牙,就诊时患牙已离体干燥超过60 min,此时的牙再植为延期再植,预后通常较差。本文对牙全脱出再植后牙根外吸收分类、特点、发病机制和牙延期再植前预处理方法的研究进展进行综述,为实现较好的牙再植预后探讨较适宜的延期再植牙处理方案提供借鉴和参考。Tooth avulsion is the most severe type of dental trauma,and tooth replantation is currently the preferred treatment method for dislocated teeth.In most cases,patients and their families fail to properly preserve dislocated teeth.At the time of treatment,the affected tooth has been dry and detached for more than 60 min,and the prognosis is usually poor.This paper provides a review of the research progress on the classification,characteristics,pathogenesis,and pre-treatment methods for tooth root resorption after complete replantation of a dislocated tooth to provide a reference and guidance for exploring suitable treatment plans for delayed tooth replantation once better tooth replantation methods have been identified.
