Abstract

We describe the treatment of a young adult male (aged 14 years 9 months) with Class III malocclusion using a mini maxillary protraction appliance, and discuss the results. The patient was treated with an acrylic cap splint-type expander and a modified maxillary protractor until a positive overjet was achieved. Edgewise fixed appliances were used to align the teeth. The treatment resulted in Class I molar occlusion, an ideal overjet, overbite and incisor angulation. A Class I molar relationship was achieved after 6 months of treatment, and the total treatment time was 1 year 6 months. Modified maxillary protractor treatment is effective for correcting skeletal Class III malocclusion.
