Find the best orthognathic surgery practices in your city, state or area. Certain jaw and cranio-facial deformities may cause significant functional impairment. These deformities include apertognathia (either lateral or anterior not correctable by orthodontics alone), significant asymmetry of the lower jaw, significant class 2 and class 3 occlusal discrepancies, and cleft palate. Aetna considers orthognathic surgery medically necessary for correction of the following skeletal deformities of the maxilla or mandible when it is documented that these skeletal deformities are contributing to significant dysfunction, and where the severity of the deformities precludes adequate treatment through dental therapeutics and orthodontics alone. Orthognathic surgery involves the surgical manipulation of the elements of the facial skeleton to restore the proper anatomic and functional relationship in patients with dentofacial skeletal anomalies.
This article provides an overview of the principles used in orthognathic surgery, which can be used to manage a broad spectrum of maxillofacial abnormalities, including congenital, developmental, and acquired deformities. Orthognathic surgery is needed when jaws don’t meet correctly and/or teeth don’t seem to fit with jaws. Teeth are straightened with orthodontics and corrective jaw surgery repositions a misaligned jaw.
This not only improves facial appearance, but also ensures that teeth meet correctly and function properly. People who can benefit from corrective jaw surgery include those with an improper bite or jaws that are positioned incorrectly. Jaw growth is a gradual process and in some instances, the upper and lower jaws may grow at different rates. The result can be a host of problems that can affect chewing function, speech, long-term oral health and appearance. Injury to the jaw and birth defects can also affect jaw alignment. Orthodontics alone can correct bite problems when only the teeth are involved. Orthognathic surgery may be required for the jaws when repositioning in necessary. Any of these symptoms can exist at birth, be acquired after birth as a result of hereditary or environmental influences, or as a result of trauma to the face.
