The prevalence of severe open bite is low, estimated at less than 1 percent of the U.S. population, but the functional and esthetic problems related to this condition can be the source of considerable psychosocial distress. Almost all patients with a severe open bite have short posterior vertical dimensions. Successful treatment requires control of the vertical position of the posterior teeth and often upward movement of the upper posterior teeth. For patients with a less severe problem, temporary skeletal anchorage may be a successful treatment approach, but there is limited long-term follow-up available on the maintenance of the treatment result. For those with a more severe problem, orthognathic surgery, involving only the maxilla or both jaws, may be the only viable treatment option. One- and five-year post-surgery follow-up data indicate that the vertical dimension continues to increase ― interestingly with more variability in the skeletal than in the dental component. Data from temporary skeletal anchorage studies involving children and adolescents, as well as patient-reported outcomes and current stability results following orthognathic surgery, will be presented.
