Ectopic eruption and impaction of the permanent maxillary canines present as a common clinical challenge in orthodontics, with a prevalence ranging from 0.8% to 2.8%. The majority of these impactions occur palatally, although labial impactions or ectopic eruptions are also encountered, particularly in cases associated with arch length deficiency. Multiple systemic and local factors have been implicated in the etiology of this condition. The complex anatomical location of maxillary canines, surrounded by critical structures and adjacent teeth, further complicates their eruption pathway. When arch space is inadequate, orthodontic extraction of premolars is a frequent intervention. However, closing the resulting spaces requires precise biomechanical planning. Segmental mechanics, a frictionless technique, offers improved control during space closure, particularly in cases with ectopic canines and proclined incisors. This case report illustrates the management of bilateral ectopic maxillary canines using first premolar extractions followed by segmental mechanics to achieve optimal alignment and occlusion.
