Maxillary protraction after surgically assisted maxillary expansion

Abstract

This case report describes the orthodontic treatment of a 32-year-old woman with a Class III malocclusion, whose chief compliant was her dentofacial esthetics. The pretreatment lateral cephalometric tracings showed the presence of a Class III dentoskeletal malocclusion with components of maxillary deficiency. After discussion with the patient, the treatment option included surgically assisted rapid maxillary expansion (SARME) followed by orthopedic protraction (Sky Hook) and Class III elastics. Patient compliance was excellent and satisfactory dentofacial esthetics was achieved after treatment completion.

Combining Circumvestibular Corticotomy with Maxillary Protraction as a Conservative Approach to Treatment in an Adolescent with Maxillary Deficiency: A Case Report with Long Term Follow-up

“…In contrast to the current results, Furquim et al [ 16 ] reported palatal tipping of maxillary incisors and labial tipping of the mandibular incisors. This result is not in line with the common dentoalveolar effects of facemask therapy which is proclination of upper incisors and retroclination of lower ones.In another attempt, some clinicians applied a Lefort I osteotomy without down fracturing, followed by extra-oral forces to protract the maxilla in the fourteen young adolescents with bilateral alveolar cleft.…”

“…They combined surgically assisted rapid maxillary expansion (SARME) with orthopedic protraction by Sky Hook. Even though they applied osteotomy cut instead of corticotomy lines, the orthopedic movement of maxillary base was lower compared with the current findings [ 16 ]. This difference could be attributed to the osteotomy technique, in which a major advancement resistance was not removed.…”
