In complete dental transposition, aligning the transposed teeth to its normal anatomic position is always a complicated and difficult challenge, which needs multiple clinical considerations. This case report illustrates an orthodontic treatment of a 20-year-old female patient who had a concave profile, skeletal and dental Class III malocclusion with anterior crossbite and complete transposed maxillary left lateral incisor and impacted canine. The correction of transposition was performed by moving the canine by maintaining its high position in the vestibular fold and use lever arm and temporary anchorage device (TAD) to facilitate traction of the maxillary canine. Vestibular incision subperiosteal tunnel access (VISTA) technique also provided as a minimally invasive approach for the tooth exposure. After 48-month of treatment duration, improvement of facial profile and favorable occlusion were achieved with the involved teeth that were moved to their clinically normal sequence without extraction.
