Intraosseous Transmigration of Impacted Canines: Report of Five Cases

Sulabha AN, Sachin Deshpande, Sameer C


Transmigration is rare and unusual anomaly involving the intraosseous migration of impacted tooth across midline regardless of the distance. This occurs almost exclusively with mandibular canines. Etiology is still unclear and is not well documented in the literature. Transmigration can occur as isolated finding or in association with other findings such as dentigerous cyst, odontomas, impactions of other teeth etc. Transmigrated canines are particularly significant due to aesthetic and functional importance. Early radiographic examination of the patient is important for the treatment. More documentation of this anomaly and future studies may lead to a better understanding of this rare anomaly, its etiology and improvement of the classification criteria. This paper presents five cases of transmigration of mandibular canines of which two were associated with dentigerous cyst, one associated with bodily rotation of canine, one associated with absence of third molars on right side.
