Maxillary canines are the most commonly impacted teeth, second only to third molars. Various treatment methods may be used to recover impacted maxillary canines. This is a report of a 14-year-old girl with a severely malpositioned impacted right maxillary canine which accompanied severe root resorption of adjacent tooth, treated by autotransplantation with a computer aided rapid prototyping model as a surgical guide. This case report demonstrates that autotransplantation can be a reliable treatment alternative, in cases with a severely malpositioned impacted canine, providing acceptable prognosis.
上颌尖牙是最常见的阻生牙，仅次于第三磨牙。可采用多种治疗方法来恢复阻生的上颌尖牙。本文报道了一名14岁女孩，其右侧上颌尖牙严重错位阻生，并伴有相邻牙齿的严重牙根吸收，通过使用计算机辅助快速成型模型作为手术导板进行自体牙移植治疗。该病例报告表明，对于严重错位阻生的尖牙病例，自体牙移植可以是一种可靠的治疗选择，并能提供可接受的预后。
