Two Different Approaches In Three-Dimensional Planning Of Orthognathic Surgery: Surgery First And Traditional Orthognathic Surgery

Abstract

In individuals with completed growth development and Class III malocclusion, orthognathic surgery is inevitable for achieving ideal occlusion and facial aesthetics. In the treatment of orthognathic surgery, it has been a long-standing approach to plan orthognathic surgery using traditional two-dimensional cephalometric planning and model surgery after fixed orthodontic treatment, which allows for the decompensation of malocclusion to improve skeletal correction and position of the teeth ideally. However, with advancing techniques, both the elimination of pre-surgical orthodontic treatment, which prolongs the treatment time and negatively affects the patient's psychology, through the Surgery First method, and the possibility of planning more accurate surgeries with three-dimensional virtual surgical planning have become widespread. In this case report, the treatment outcomes of two adult individuals with bimaxillary orthognathic surgery planned for skeletal Class III malocclusion using three-dimensional virtual surgical planning software will be presented, comparing the results achieved with both the traditional method and the Surgery First method.
