Orthodontic treatment of a transmigrated mandibular canine: a case report.

Background: Intraosseous migration of a lower canine across the midline is a rare dental anomaly. The treatment options include: forced eruption of the unerupted tooth using orthodontic traction, autotransplantation, extraction followed by prosthetic replacement.

Aim: To report the management of a transmigrated lower right canine.

Method: The treatment involved surgical, orthodontic and cosmetic dental treatment. No permanent teeth were extracted.

Results: The transmigrated canine was placed between the left central and lateral incisors and the crown recontoured to simulate a lateral incisor. An acceptable aesthetic and functional outcome was gained.

Conclusion: Transmigration is a rare dental condition that can be treated successfully with a collaborative effort from several dental disciplines.
