Surgical correction of malocclusion is used in cases of severe deformation of the facial skeleton and dentition in which the orthodontic treatment with removable and nonremovable devices is ineffective. It is carried out in the case of frontal and lateral opened bite, dysplasia of the chin, or facial asymmetry. Orthodontists in Tennessee carry oat such operations. The surgical correction often used to put the upper and lower jaw to the new position. In these cases, all corrections are made exclusively through the mouth. The operation is performed under general anesthesia in the hospital with a dental surgeon, and can take several hours depending on the complexity of the surgery.
