Abstract
This article aims to illustrate a case of mandibular canine transmigration crossing the midline and erupting labially to the lower incisors and discuss its general prevalence, etiology, and orthodontic management. Cases of canine transmigration are rare and mostly occur due to retained deciduous predecessors or dental lamina aberrations. This anomaly is appropriately diagnosed radiographically. As canines are significant for masticatory function, arch stabilization, and esthetics, it is imperative to preserve them by orthodontic correction or surgical transplantation, unless the prognosis is appalling. A 13-year-old girl presented with extra erupting teeth in the front lower teeth region. A transmigrated 43 across the mandibular midline erupted labially to 31, confirmed by orthopantomogram and cone beam computed tomography. Thirty-three erupted mesially and labially to 32. Treatment involved the extraction of retained 83 and transplantation of 43, along with the application of traction force to bring 33 into its anatomical position.
