Autotransplantation as a Therapeutic Approach for Canine Inclusion and Transmigration in Adolescent Patients: A Case Report.

BACKGROUND: Bony inclusion of permanent teeth refers to the failure of a tooth to erupt within the expected timeframe, commonly affecting upper and lower canines. The etiology remains debated, with genetic factors and eruption guidance disturbances being the primary hypotheses. CASE REPORT: This case report describes the management of a 13.6-year-old male patient presenting with impacted upper and lower canines (1.3, 2.3, 3.3) and transmigration of tooth 3.3. The patient exhibited a Class I malocclusion, midline deviations, and significant dento-dental discrepancies, mainly due to conoid lateral incisors. The treatment plan included orthodontic treatment to create adequate space, followed by autotransplantation of teeth 2.3 and 3.3. The autotransplantation procedure involved atraumatic extraction, careful preparation of the recipient site, and minimal extra-alveolar time to preserve periodontal ligament vitality. After 18 months of treatment, the patient achieved a stable Class I occlusion, with optimal positioning of the impacted canines, improved smile aesthetics, and centered midlines. However, root resorption was observed in tooth 3.3, requiring endodontic treatment. Despite this complication, the overall result was functionally and aesthetically successful. CONCLUSION: This case highlights the effectiveness of dental autotransplantation as a viable therapeutic option for impacted canines in growing patients, providing both functional and aesthetic benefits.
