The diagnosis of an impacted incisor with dilaceration refers to a dental deformity characterized by an angulation between the crown and the root, causing noneruption of the incisor. In the past, surgical extraction was the first choice in treating severely dilacerated incisors. The purpose of this case report was to present the correction of a horizontally impacted and dilacerated central incisor through 2-stage crown exposure surgery combined with continuous-force orthodontic traction. The tooth was successfully moved into its proper position. The treatment is discussed, and the orthodontic implications are considered, with a review of the current literature on this topic.
诊断埋伏阻生伴有扭转的切牙是一种牙体畸形，其特征为牙冠与牙根之间成一定角度，导致切牙无法萌出。过去，对于严重扭转的切牙，手术拔除是首选治疗方法。本病例报告的目的是介绍通过 2 期冠暴露手术联合持续力正畸牵引来矫正水平埋伏阻生伴有扭转的中切牙。该牙成功地移动到了适当的位置。讨论了该治疗方法，并考虑了正畸学的影响，同时回顾了该主题的当前文献。
