What's that ?
Orthognathic surgery is a branch of maxillofacial surgery.
It is used to correct certain imbalances between the jaws, when these are too large to be treated by orthodontics alone, especially when growth is complete and it is no longer possible to act by orthopedics.
Before any treatment, a very complete check-up will be performed, as well as various x-rays and dental impressions. Dental occlusion (closing of the jaw) will be evaluated. The different functions will be studied and the aesthetic impact will be analysed.
The intervention may concern one or both jaws. Once the need for the intervention is established, the orthodontist and the maxillofacial surgeon will prepare the treatment plan together.
Interest of orthognathic surgery
The indications for orthodontic-surgical treatment are most often aesthetic when there is a major injury, such as a gummy smile or a chin position too far back or too far forward. Functional motivation often concerns patients with Obstructive Sleep Apnea Syndrome.
Maxillo-mandibular advancement is described today as the most effective surgical treatment of SAHOS in adult patients with a cure in more than 90% of cases. This operation results in the release of the upper airway.
Pre-surgical orthodontics
The orthodontist must make an orthodontic preparation of the patient to be operated on. This involves straightening the teeth of each dental arch ideally on their skeletal base. This phase lasts about 12 to 15 months. At the end of this orthodontic preparation, each of the dental arches being straightened on its base, the inter-arch dental shift will be amplified because it will correspond to the skeletal shift.
At the end of this preparation phase, the surgeon performs the operation, under general anaesthesia, in order to correct the position of the jaws. No scar will be visible. The osteotomies will correct the skeletal shift and at the end of the operation, the dental arches will be in functional occlusion.
After surgery, an orthodontic finishing phase to improve the proper fit of the dental arches and optimize occlusion will be continued. This phase lasts approximately 6 months.
