Treatment of Class III malocclusion in a young adult with reverse pull face mask

Abstract

Class III malocclusions are usually growth-related discrepancies, which often become more severe until growth is complete. This case report describes the treatment of a young girl aged 11 years 3 months who had a skeletal Class III malocclusion with a flattening of mid facial region. She also had constricted maxillary arch and high labially placed canine. The treatment plan included a slow palatal expansion, reverse pull facemask appliance, and fixed edgewise appliances. The treatment resulted in skeletal Class I and dental Class I molar and canine occlusion, an ideal overjet, overbite, incisor angulation and facial esthetics was greatly improved after 21 months of treatment. Stability of the treatment result was excellent in 1 year 5 months follow-up at the age of 14 years and 7 months.
