Abstract

The maxillary canine is especially important as it has the longest root, provides guidance for lateral movement of the mandible and masticatory function and is a key in esthetics due to its position. Maxillary canine has the longest time to develop and a complex route from the place of formation to the site of eruption, and so it is prone to impaction more than other teeth. The clinician should consider the various treatment options : (a) No treatment and observation, (b) surgical exposure and orthodontic traction (c) autotransplantation (d) extraction. Surgical exposure of the canine and orthodontic treatment to bring the tooth into the line of occlusion is considered the most desirable approach. This case presents the results of treatment for impacted maxillary canine by surgical exposure and orthodontic tooth movement.
