Severe dento-facial deformity treated with quadangular

Le Fort-II osteotomy and various surgical procedures Report of a case

Abstract

A 27 year-old male who suffered from severe maxillary retrusion and mandibular protrusion with several tooth caries and impactions, lingually tipped teeth and alveolar bone and collapsed arches was presented. In order to accomplish a completely reasonable leveling of the dental arches and decompensation of the incisor area in both arches, anterior and posterior alveolar osteotomies and corticotomy were done during preoperative orthodontic treatment. Finally, two jaw surgerie (quadangular Le Fort-II osteotomy and sagittal split ramus osteotomy) were chosen to correct the abnormal relationship of the dento-facial complex with severe infraorbital hypoplasia and mandibular prognathism. Desirable functional occlusion and preferable skeletal and soft tissue esthetics were obtained.
