A unique treatment approach for maxillary canine-lateral incisor transposition.

Maxillary canine-lateral incisor transposition [Mx3-2] is a relatively rare anomaly, with both dental and facial esthetic implications. A challenging treatment approach for selected cases is described in detail, including the mechanics and sequencing used to align the completely transposed teeth to their normal anatomic position in the arch. The long-term esthetic outcome warrants the longer treatment time and greater efforts required in the successful treatment of this unusual abnormality.
