A female patient with severe class III skeletal malocclusion and hypodivergent face was treated with a conventional orthognatic treatment. Our patient had a dental class III canine and molar relationship, an anterior cross bite and a gummy smile. Her severe anomaly was responsible of some functional issues such as TMJ disorder and difficulties at mastication. We observed a straight profile with a shy and narrow smile. The treatment began with orthodontic surgery preparation(decompensation) that lasted 24 months. Then a bimaxillary surgery was conducted with Lefort 1 osteotomy of advancement and impaction, associated to mandibular osteotomy in order to rotate the lower jaw. Finally, the finishing orthodontic phase had an objective: to close posterior open bite with intermaxillary elastics. Important amelioration of esthetics, oral functions and especially better self-esteem of the patient were obtained. Cephalometric superposition demonstrated that pharyngeal airways width was improved and skeletal discrepancy was corrected.
