Abstract:

In this case report a case is presented with skeletal class III malocclusion which were treated with proper planned orthognatic surgery and orthodontic treatment. Our patient was a girl with 16 years, 3 months of chronologic and Ru period of skeletal age. A concave soft tissue profile and Class III molar relation was detected in extraoral and intraoral examination. Cephalometric evaluation revealed a significant Class III skeletal discrepancy (ANBº= -6). Presurgical orthodontics involved decompensation of incisor inclinations. Surgical operation was performed under general anesthesia with Lefort I downfracture technique. Maxilla were advanced 8 mm and fixed with rigid internal fixation. Post-surgical orthodontic treatment involved final positioning of the teeth and settling the occlusion. At the end of the treatment, Class I dental and skeletal occlusion and a straight soft tissue profile were achieved. Keywords: Orthognatic Surgery, Class III, Maloclusion
