ABSTRACT

Skeletal class III is the result of mandibular prognathism, growth deficiency of the maxilla or a combination of both. Historically, surgical correction of class III has been achieved only by mandibular setback surgery. With advances in knowledge and techniques, corrective surgery progressed to include bimaxillary and triple surgery (maxilla, mandible and chin). In the last decade, the frequency of jaw surgery decreased less than 10% class III patients, while bimaxillary surgery has come to use in about 40% of the class III patients. Both, bimaxillary surgery and surgery, can improve occlusion, masticatory function and aesthetics, significantly changing the position of the mandible, maxilla and chin. It is intended to explain the development and result in a Class III patient whose treatment was triple orthognathic surgery (anterior segmental, reverse sagittal osteotomy and forward genioplasty).
