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

In individuals with completed growth development and Class III ma-locclusion, 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-dimensi-onal cephalometric planning and model surgery after fixed orthodontic treat-ment, 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-surgi-cal orthodontic treatment, which prolongs the treatment time and negatively affects the patient's psychology, through the Surgery First method, and the pos-sibility of planning more accurate surgeries with three-dimensional virtual sur-gical planning have become widespread. In this case report, the treatment out-comes 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.
