Abstract

Impaction of mandibular canine is not common, and transmigration of mandibular canine is rare. Treatment of impacted canine can be removal of physical obstacle and periodic observation, surgical exposure of impacted tooth and orthodontic traction, autotransplantation, surgical extraction. Management of impacted canine depends on existence of physical obstacle, position and direction of impacted tooth, space available for canine eruption, stage of root development. Of the two case in this report, one case involved impaction of lower canine with odontoma and dentigerous cyst that is treated by surgical exposure and orthodontic traction. The other case involved transmigration of lower canine with supernumerary teeth. It was thought difficult to treat only by orthodontic treatment, so the impacted canine was transplanted to its normal position and orthodontic treatment was conducted.

Key Words: Impacted mandibular canine, Transmigration, Surgical exposure, Autotransplantation
