Correction of Maxillary Canine-First Premolar Transposition Using Two Distinct Treatment Approaches: Case Reports

Tooth transposition is a rare eruption anomaly that most frequently affects the maxillary canine and first premolar. It can cause impaction, esthetic concerns, and functional problems. Accurate diagnosis and individualized treatment planning are essential for safe and effective management. This report presents two cases managed using different approaches. In the first case, a 10-year-old boy with moderate displacement was treated with surgical exposure and orthodontic traction. Careful premolar repositioning prevented root interference, and the canine was successfully relocated, with stable alignment after 2 years. In the second case, an 11-year-old boy presented with severe displacement and root resorption risk. Autotransplantation was performed after the recipient site was prepared, and the transplanted canine healed uneventfully. At follow-up for 2 years, the tooth remained functional and pathology-free, although calcific obliteration of the pulp canal was observed. Careful diagnosis and long-term monitoring are critical for achieving stable esthetic and functional outcomes.
