Dilaceration and angulation in upper incisors consequent to dental injuries

Abstract: The treatment of three cases of dilacerated incisors are reported with long-term follow-ups. Impacted incisor with dilaceration refers to a dental deformity characterized by an angulation between the crown and root preventing the incisor from eruption. Surgical extraction used to be the ®rst choice in treating the severely dilacerated incisor. After a brief review of the literature, the surgical and orthodontic treatment of these patients are described. By combining two stages of the crown exposure surgery with light force orthodontic traction, the impacted dilacerated incisors were successfully moved into proper position.
