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.
To report the management of a transmigrated lower right canine.
The treatment involved surgical, orthodontic and cosmetic dental treatment. No permanent teeth were extracted.
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.
Transmigration is a rare dental condition that can be treated successfully with a collaborative effort from several dental disciplines.

    • "In cases where the transmigrated canine is erupted and transpositioned in the dental arch, the tooth can be orthodontically aligned and recontoured accordingly. Trakyali et al. [28] reported the management of a transmigrated lower right canine, which was erupted between the left central and lateral incisors. The crown was recontoured to simulate a lateral incisor, and an acceptable aesthetic and functional outcome was gained. "

    ABSTRACT: The purpose of this paper is to present the first case of unusual reverse oblique (110 degrees to midsagittal plane) migration of mandibular right canine crossing the jaw midline and piercing the lower border of the mandible at the level of the opposite canine and also to report two more cases of transmigrated mandibular canine and one case of transmigrating mandibular canine. Mandibular canines are "cornerstone" of dental arch; their importance is manifested by their efficiency in masticatory function, stability of dental arch, and aid in maintaining natural facial expression. Early detection of this anomaly can help preserving these canines by orthodontic intervention or by surgical transplantation. This developmental anomaly is properly diagnosed by radiographic evaluation, which is primarily based on the panoramic radiograph. In patients with overretained deciduous canines or missing permanent canines, an intraoral radiograph should be supplemented with panoramic radiograph. This paper discusses the importance of early diagnosis of canine transmigration in treatment planning and reviews the various possible treatment options.

    • "Surgical removal, transplantation, radiographic follow-up, and surgical exposure with orthodontic treatment are suggested as treatment options for transmigrated canines.7 Orthodontic correction of impacted transmigrated canines is difficult due to unfavorable position of the impacted tooth. Until now, successful corrections of transmigrated canines using orthodontic treatment have been rarely documented in the literature.10,11 In Case 3, the impacted transmigrated canine was erupted successfully after orthodontic traction and its alignment is still in progress (Fig. 7).

    ABSTRACT: Transmigration of an impacted tooth through the symphyseal suture is a rare and special developmental anomaly of unknown etiology that is unique to the mandibular canine. Maxillary canine transmigration is even rarer. Transmigrated canines are particularly significant due to the aesthetic and functional importance. A maxillary lateral incisor crossing the mid-palatal suture has never been reported in the literature. The aim of this report is to present the first case of simultaneous transmigration of a lateral incisor and canine in the maxilla. The paper also reports four unusual cases of unilateral canine transmigration in the maxilla and mandible and successful eruption of one of the transmigrated mandibular canines following orthodontic traction. Etiology of transmigration and its clinical considerations are also discussed.

    ABSTRACT: Transmigration is a rare and special phenomenon in that intraosseous tooth migration takes place, through the midsymphyseal or mid palatine suture. Transmigration typically affects the mandibular canines. These teeth usually remain impacted and asymptomatic but in some cases they ectopically erupt in the midline or next to the contralateral side. Transmigrated teeth can cause neurologic symptoms and pressure resorption of the adjacent teeth roots. A 15-year-old girl was referred to our clinic complaining of pain in the inferior incisives. On intraoral examination, right mandibular deciduous canine was seen to be retained. Panoramic radiograph revealed a horizontally impacted right mandibular permanent canine migrated toward the midline and located below the apices of the incisives. The tooth was surgically removed under general anesthesia. The presence of an overretained mandibular deciduous canine should always be investigated radiographically.
