Orthodontic Treatment for Constricted Maxilla and Prognathic Mandible with Severe Crowding Via 2-Jaw Orthognathic Surgery-A Case Report

TL;DRAbstract

This is a case of a 26 year-old female who complained of mandibular prognathism and malocclusion. Extraoral view revealed a concave profile with midface deficiency, mandibular prognathism, and chin deviation to right side by 4 mm. Class 111 malocclusion along with bilateral posterior crossbite and severe crowding were noted. Panoramic X-ray showed #83 retained, and #43 deeply impacted approximating to the mandibular lower border with a mass of radiopacity over it. Orthodontic treatment combined with a 2-jaw orthognathic surgery in which removal of #43 deep impaction was suggested. Before full mouth bonding, we referred the patient to remove #83 and the radiopaque mass to facilitate further orthodontic tooth movement. Pathology report confirmed the mass as a compound odontoma. At the preoperative orthodontic stage we performed dental decompensation. In the upper arch, two first premolars and third molars were extracted for crowding relief and alignment. In the lower arch, we created ca
