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.
