Clinical Application of Surgery-First Orthognathic Surgery in Patients with Class III Dentofacial Deformities

The conventional dentofacial deformity management sequence, using orthognathic surgery, is presurgical orthodontic treatment, orthognathic surgery, and postsurgical orthodontic treatment. This approach has been the standard for achieving stable and predictable results in correcting dentofacial deformities; few studies have investigated possible modifications to this approach. Although the conventional approach has many advantages, some disadvantages exist, such as the length of the presurgical orthodontic treatment, related delays in orthognathic surgery, and possible aggravation of facial aesthetics during the presurgical period, especially in patients with Class III dentofacial deformities. However, if a surgery-first orthognathic approach is possible, these presurgical drawbacks can be avoided.
