Anterior open bite correction by Le Fort I or bilateral sagittal split osteotomy.

Some of the most challenging dentofacial deformities facing surgeons and orthodontists are anterior open bite malocclusions. Determining the cause for the development of an anterior open bite and formulating a diagnosis are complicated by the role of neuromuscular and genetic influences. Long-term skeletal and dental stability has been a concern because of the influence that the neuromusculature has on the repositioned jaws and stability of teeth after vertical orthodontic mechanics required for closing open bites.
