A case report of a 7-year-old boy who had Class III skeletal pattern is presented. The maxilla was deficient in anteroposterior and transverse dimensions, causing a slightly concave profile, a crossbite relationship of most of the anterior and posterior teeth, and upper anterior crowding. The rapid palatal expansion therapy effectively uprighted the posterior segments and developed the arches. Alignment, leveling and development of a good functional occlusion was accomplished with the .022" x .028" standard edgewise appliance.
