title: Eight-year stability of a severe skeletal anterior open bite with a hyperdivergent growth pattern treated with an edgewise appliance and chin cup therapy.
abstract: An adolescent boy with an Angle Class II Division 1 malocclusion had a hyperdivergent growth pattern with an excessive lower facial height and an anterior open bite. Combined orthodontic and surgical treatment should be considered for patients with a skeletal anterior open-bite malocclusion. For patients who do not want surgery, however, a 0.022 × 0.028-in nontorqued, nonangulated fixed appliance with a chincup as adjunct therapy is an alternative that can have excellent results. The final outcome of this treatment were great improvements in function, esthetics, and posttreatment stability after 8 years.
