Long-term outcome in a patient with a dentoskeletal open-bite malocclusion treated without extraction.

This case report describes the treatment of a patient with a Class II malocclusion with an anterior open bite. The patient, a girl 16 years of age, had a significant anteroposterior discrepancy and a high-angle tendency. Her face was convex, with competent lips. Intraorally she had an anterior open bite of 3 mm, space in the mandibular arch, and an overjet of 2 mm. High-pull headgear, anterior intermaxillary elastics, and appropriate wire bending were used to close the bite and to correct the anteroposterior dental relationship. Modification of a tongue thrust habit helped to correct this significant malocclusion and provided stability at 11 years posttreatment.
