Orthodontic treatment primarily affects the appearance of the teeth and the contour of the lips, however, it is possible to create skeletal changes with functional orthodontic treatment applied during growth and development periods, but such changes in places that remain out of lips and teeth that are hard and soft tissues such as nose and jaw tip are not possible in adults. Thanks to orthognathic surgery, significant changes can be obtained in the nose, lips and chin in adult individuals. This way, individuals gain a new external appearance and are very satisfied with this change.

The procedures performed in cooperation with orthodontics and surgery in order to correct the skeletal relationship in the correction of dentofacial deformities in patients with severe skeletal deviation and who have completed their growth is called orthognathic surgery. The purpose of orthognathic surgery is to bring the patient to a desired psychosocial position by giving patients a better aesthetic appearance and function.

Orthognathic surgery operations are routinely used in the correction of many dentofacial anomalies, the aesthetic improvement of the tooth row and face, and the correction of all jaw and dental functions with applications applied to both the lower jaw, upper jaw and both. With these operations, it is possible to move the jaws in all three directions, which makes it possible to be applied in cases that exceed the limits of orthodontic treatment. Studies have shown that as a result of the treatment of severe dentoalveolar anomalies that cannot be corrected with orthodontic treatment, with orthognathic surgery, people have a much more effective occlusion function, and even the temporomandibular joint (TMJ) disorders and pain that were present before the operation significantly improved due to the improved occlusion.

The current problem is determined by radiographs, photographs and model examination. This operation, which requires the orthodontist and the surgeon to work together, is performed by a plastic surgeon or maxillofacial surgeon under general anesthesia after the teeth are sorted with orthodontic treatment. Orthodontic treatment is applied with brackets (braces) before orthognathic surgery. In order to ensure that the teeth are well bite (occlusion) with each other after surgery, the teeth must be brought to their correct positions with orthodontic treatment. Otherwise, functions such as good chewing ability cannot be achieved as a result of the surgery.

In cases where the lower jaw is in front or in behind, upper jaw is in front or in behind, asymmetry in the face and lower jaw, and when gums are excessively visible in the upper jaw orthognathic surgery should be applied.

Orthognathic surgery is performed after the individual’s growth is completely over.
