Abstract

Delayed eruption of a maxillary incisor results in midline shift, the space occupied by adjacent teeth and different levels of alveolar height. Extraction or surgical/orthodontic therapy is the most common treatment for a impacted maxillary incisor. Surgical repositioning provides another option for treatment of this problem. The advantages of this approach include immediate esthetic improvement, use of a single and simplified surgical procedure, simple and short orthodontic therapy, a normal gingival margin and the possibility of the developing root adapting to the new position. Autotransplantation of an immature tooth provides for possible adaptation of the developing root apex to the new position. A root with an open apex has good chance of pulp revascularization after transplantation.

Key Words: Impacted tooth, Surgical repositioning, Autotransplantation
