Abstract
Impacted permanent canines are relatively common and have been documented extensively in the literature. Mandibular canine impaction occurs approximately 20 times less frequently than maxillary canine impaction. In the general population, the incidence of mandibular canine impaction ranges from 0.35 to 0.44 percent. An even less common finding is the migration of a mandibular canine from its normal position to the contra lateral hemi arch, crossing the midline. This phenomenon is known as transmigration, and it occurs almost exclusively with mandibular canines; only two published reports have described maxillary canine migration to the contra lateral side. The aim of this study is to present prevalence of mandibular canine transmigration as a rare dental ectopic that creates surgical, orthodontic, restorative and interceptive problems. Etiologic and pathogenetic aspects of mandibular canine transmigration are examined through an international literature review. Impacted or transmigrated teeth must be diagnosed clinically and radiographically especially in terms of orthodontic treatment planning. Clinically, over-retention of the primary canine, proclination of the mandibular teeth, and an enlarged symphyseal area are signs of transmigration. To confirm three-dimensionally transmigrated and impacted tooth localization radiographically, dental pantomographs, occlusal, periapical, lateral cephalometric, and submentovertex projections can be used. Computed tomography is the gold standard for three-dimensional localization of impacted teeth. Surgical extraction appears to be most favored treatment for migrated canines, rather than to effort to bring the tooth back to its original place.Transplantation, exposure and orthodontic alignment, andmethod of observation are rarely methods of choice. According of this type of treatment several clinical cases with mandibular transmigrated impacted canines will be present Treatment consisted of surgical extraction and periodic clinical and radiologic follow-up visits. Precise impacted canine diagnosis is essential for the best treatment plan; it validates the treatment time and allows reducing possible complications. Key Words: Transmigrated canine; tooth migration; impacted canine.
