Abstract

Skeletal class III malocclusion can be caused by excessive mandibular growth, maxillary hypoplasia, or a combination of both. The aim of this study was to present a multidisciplinary treatment of a 28 year-old female with a skeletal class III malocclusion and bilateral hypodontia of the first and second maxillary premolars. Orthodontic treatment, as a part of the patient’s preparation for surgery, included a straight wire appliance using Roth prescription for both dental arches. A transpalatal distractor (TPD) was used to correct the transversal maxillary deficiency. The expansion was later continued using the quad-helix appliance. The second stage of surgical management included the bimaxillary osteotomy (BIMAX) in order to correct the skeletal malocclusion (mandibular prognathism and maxillary hypoplasia). Orthodontic treatment was continued after surgery, until the normal occlusal relationships were restored. The outcomes included a complete functional repair of the patient’s stomatognathic system and a significant improvement of the aesthetic appearance of her face. Multidisciplinary management was used involving orthodontic and surgical strategies. The treatment restored normal occlusal relationships, improved the stomathognatic function, the patency of upper airways as well as the aesthetic appearance of the patient’s face and smile.

Key words
