Treatment of an impacted dilacerated maxillary central incisor.

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.
