title: Unusual orthodontic approach to a maxillary canine-premolar transposition and a missing lateral incisor with long-term follow-up.
abstract: In this case report, we present an unusual approach that was used to treat a 14-year-old patient with a bilateral canine-premolar transposition and a missing maxillary lateral incisor. The orthodontic treatment involved maintaining the transposition and creating a space for lateral incisor replacement. Toward the end of the treatment, accentuated buccal root torque was performed, and lateral group function was established to improve the treatment outcome. Finally, an ideal esthetic and functional occlusion was achieved. The 8-year posttreatment follow-up records show the stability of this treatment.
