Management of tooth avulsion in the permanent dentition often presents a challenge. Definitive treatment planning and consultation with specialists is seldom possible at the time of emergency treatment. Replantation of the avulsed tooth can restore esthetic appearance and occlusal function shortly after the injury. This article describes the management of a child with an avulsed maxillary permanent incisor that had been air-dried for about 18 hours. The replanted incisor retained its esthetic appearance and functionality 2 years after replantation, yet the long-term prognosis is not good because of progressive replacement root resorption.
恒牙列牙齿脱位的处理往往具有挑战性。在急诊治疗时，很难进行明确的治疗规划并咨询专家。脱位牙齿的再植可以在受伤后不久恢复美观和咬合功能。本文描述了一名上颌恒切牙脱位的儿童的处理情况，该牙齿已风干约18小时。再植的切牙在再植后2年保持了美观和功能，但由于进行性替代性牙根吸收，长期预后不佳。
