A documented case involving the simultaneous avulsion of two maxillary incisors, intraorally and extraorally, was reported. Long-term observations following replantation treatment revealed several interesting clinical features: The prognosis of replanted teeth may be more favorable following intraoral avulsions. The intrusion phenomenon associated with replanted incisors appears to be directly related to replacement root resorption or ankylosis; occlusal forces may be a factor. Teeth extraorally avulsed for a few hours may still provide a useful function, albeit temporary, with replantation treatment. These teeth may not reveal clinical ankylosis or replacement resorption for periods of 1 to 2 years, or possibly longer, following replantation. Long-term studies can help evaluate replantation techniques.
报告了一例涉及两颗上颌切牙同时发生口内和口外撕脱的病例。再植治疗后的长期观察揭示了几个有趣的临床特征：口内撕脱后再植牙的预后可能更有利。与再植切牙相关的嵌入现象似乎与替代性牙根吸收或牙根粘连直接相关；咬合力可能是一个因素。口外撕脱数小时的牙齿，尽管是暂时的，但再植治疗后仍可能发挥有用的功能。这些牙齿在再植后1至2年或可能更长时间内可能不会出现临床牙根粘连或替代性吸收。长期研究有助于评估再植技术。
