Nonsurgical correction of skeletal deep overbite and class II division 2 malocclusion in an adult patient.
Treatment modalities for Class II Division 2 malocclusion include growth modification, dental compensation, and surgical-orthodontic therapy; which treatment is chosen depends on the patient's age and growth potential. Deep overbite can be corrected by intrusion of anterior teeth, extrusion of posterior teeth, or a combination of both. Treatment considerations include the patient's facial profile, skeletal pattern, growth potential, and severity of dental malocclusion. Here, we present the nonsurgical orthodontic treatment of an adult patient with deep overbite and underlying skeletal Class II discrepancy. He had a hypodivergent facial pattern, Class II Division 2 malocclusion, and traumatic deep overbite due to supereruption of the mandibular anterior teeth. He refused orthognathic surgery but would accept orthodontic treatment alone, with the understanding that the treatment results could be compromised. We corrected the deep overbite by proclining the mandibular incisors; this helped to level the exaggerated curve of Spee. The posttreatment occlusion was significantly improved, both functionally and esthetically, with stable interincisal contacts. However, the improvement in occlusion and esthetics was achieved at the expense of reduced periodontal support for the mandibular anterior teeth.
