Treatment of a young adult with Class III malocclusion using a modified mini maxillary protractor: a case report

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.

Comparison of the soft and hard tissue effects of two different protraction mechanisms in class III patients: a randomized clinical trial

“…MMP, firstly described by Altug and Arslan [10], was presented to be an effective maxillary protractor to correct maxillary deficiency [18]. In addition, the authors reported that the MMP was smaller, lacked of the long vertical bar of conventional FM, and had minimal disadvantages in growing patients [17]. However, there was limited information about the soft tissue effects of this appliance [16] and the comparison of its effects with a conventional FM/ RME was neglected in the literature.…”

“…However, the appliance has a long vertical bar in front of the face, and thus, it has aesthetic disadvantages [17]. MMP, firstly described by Altug and Arslan [10], was presented to be an effective maxillary protractor to correct maxillary deficiency [18].…”
