Tooth transposition is a positional interchange of two adjacent teeth. Transposition most often occurs at maxillary canine. Moving transposed teeth to their normal positions is challenging because this requires bodily movement and translation of one tooth to pass another. This procedure may cause damage to the teeth or supporting structures. We report a case of complete transposition of maxillary canine and lateral incisor. Transposed teeth were successfully moved orthodontically to their normal positions. Multiple mechanics were meticulously applied to achieve complete correction of the tooth positions and to minimize root resorption and/or periodontal defects of canine and lateral incisors. Factors concerning treatment planning for transposed teeth are discussed.
