ABSTRACT
Anteroposterior discrepancy between the maxilla and mandible, in which the mandible occludes in front of the maxilla, may be due to a maxillary bone defect, an excess of the mandible, or a combination of both. Class III malocclusion, despite having a strong genetic basis, presents multifactorial etiology, with a prevalence of 1-5% in the white population and close to 13% in Asians, considered by the World Health Organization as the third place in oral health problems. We present the case of a 23-year-old male patient with a diagnosis of Angle's class III malocclusion with retrusion of the midface. Combined orthognathic surgery was performed, which included advance LeFort I osteotomy plus sagittal osteotomy for mandibular retroposition, together with pre- and postoperative orthodontic treatment in order to establish occlusal stability prior to orthognathic surgery. A radical change is achieved clinically and cephalometrically in the patient, showing an expected frontonasal, nasolabial and mentolabial angle. We can conclude that combined orthognathic surgery represents a powerful arsenal at our disposal to be able to treat all the alterations that affect dental occlusion, facial skeletal harmony and aesthetics that cannot be treated with orthodontics or a simple orthognathic procedure.REFERENCES
