CANINE TRANSMIGRATION: OUSTING THE DEVIATED TOOTH

ABSTRACT

Transmigration is a rare pre-eruptive phenomenon in which intraosseous migration of tooth takes place across the midline. These teeth usually remain impacted and asymptomatic but some may erupt ectopically either in midline or next to contralateral side. Transmigrated teeth can cause resorption of the adjacent teeth. The current case report depicts the management of transmigrated and impacted permanent left mandibular canine in a 11-year-old girl. On intraoral examination, primary mandibular central incisors were retained. The orthopantomogram revealed an impacted permanent left mandibular canine migrated toward the midline and located below the apices of the retained primary mandibular central incisors and permanent mandibular central incisors were congenitally missing. The treatment opted was extraction of retained primary mandibular central incisors followed by surgical exposure of impacted left mandibular permanent canine and its orthodontic extrusion with the aim to achieve proper alignment, function and aesthetics.
