Abstract

This case report describes the treatment of a 16-year-old girl with a unilateral posterior buccal crossbite, a unilateral Class II molar relationship, and a maxillary right canine high in the labial sulcus. The treatment plan included surgically assisted unilateral maxillary expansion for the correction of the buccal crossbite, with simultaneous dentoalveolar distraction of the maxillary right canine into the extraction space of the first premolar aided by skeletal anchorage. Reduced orthodontic treatment time was facilitated by these 2 surgical procedures. A pleasing esthetic result and a good functional occlusion were achieved in 13 months.
