Orthognathic surgery (/ ˌ ɔːr θ ə ɡ ˈ n æ θ ɪ k /), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot ...
A Le Fort I osteotomy surgically advances the upper jaw to correct misalignment and deformities. It is used in the treatment for several conditions, including skeletal class II malocclusion, cleft lip and cleft palate, vertical maxillary excess (VME) or deficiency, and some specific types of facial trauma, particularly those affecting the mid-face.
Mandibular setback surgery is a surgical procedure performed along the occlusal plane to prevent bite opening on the anterior or posterior teeth and retract the lower jaw for both functional and aesthetic effects in patients with mandibular prognathism. [1] [2] It is an orthodontic surgery that is a form of reconstructive plastic surgery. [3]
In the late 1970s advancement of the lower jaw (mandibular advancement) was noted to improve sleepiness in three patients. Subsequently, maxillomandibular advancement was used for patients with obstructive sleep apnea. Currently, maxillomandibular advancement surgery is often performed simultaneously with genioglossus advancement (tongue ...
Jaw surgery may be required to fix severe malocclusions. [41] The bone is broken during surgery and stabilized with titanium (or bioresorbable) plates and screws to allow for healing to take place. [42] After surgery, regular orthodontic treatment is used to move the teeth into their final position. [43]
Surgery may be required on rare occasions. This may include surgical reshaping to lengthen or shorten the jaw (orthognathic surgery). Wires, plates, or screws may be used to secure the jaw bone, in a manner similar to the surgical stabilization of jaw fractures. Very few people have "perfect" alignment of their teeth.
The specialty avoids making irreversible changes to the bite or jaw and instead treats TMJ disorders with tools like counseling, dietary changes, medication, physical therapy, and removable dental ...
Following surgery, patients may require up to six weeks of rest before they are able to return to the demands of their daily life. [6] As all patients heal slightly differently, ORIF may result in a less-than-ideal correction of facial bones, resulting in poor occlusion or facial asymmetries. Furthermore, as with any surgery, ORIF comes with ...
