Abstract
Ankylosis is the abnormal adhesion of alveolar bone to dentin or cementum and commonly seen after traumatic dental injuries. Treatment of impacted and ankylosed teeth solely by orthodontics alignment may be challenging. Consequently, several treatment alternatives have been proposed for the management of ankylosed teeth involving extraction, surgical luxation, and osteotomy followed by dentoalveolar distraction or conventional orthodontic treatment. This case report describes a 55-year-old female who was referred by her orthodontist due to an impacted and ankylosed maxillary upper left canine. A dentoalveolar segmental osteotomy with immediate repositioning of an upper canine was performed. One year after final orthodontic treatment a satisfying occlusal and esthetic treatment outcome was obtained.

Several treatment modalities have been advocated for the management of an impacted and ankylosed tooth comprising extraction and prosthetic rehabilitation, surgical luxation of the tooth followed by orthodontic traction or dentoalveolar segmental osteotomy followed by dentoalveolar distraction or conventional orthodontic treatment
Summary
Tooth ankylosis is an anomalous eruption characterized by localized fusion of cementum and surrounding alveolar bone with obliteration of the periodontal ligament. It is apparently caused by mechanical, thermal or metabolic trauma to the periodontal membrane during or after tooth eruption [1]. Single-tooth segmental osteotomy with immediate placement of the segment in the correct dental position will from a clinical perspective be an advantage, since the total treatment time and morbidity will be decreased The purpose of this case report is to describe the treatment of an impacted and ankylosed upper maxillary canine using segmental osteotomy with immediate repositioning of the tooth and to summarize the current knowledge about this treatment modality
