Abstract
The treatment of deep bite includes growth modification, orthognathic surgery and orthodontic treatment by intrusion of the anterior teeth or extrusion of the posterior teeth in either or both of the maxillary and mandibular arches. Decision for molar extrusion or incisor intrusion should be decided by the underlying skeletal or dental discrepancies and the vertical positions of the incisal edges of the maxillary incisors relative to the upper lip. Treatment considerations also should include the patient’s facial profile, skeletal pattern, growth potential, and severity of dental malocclusion. This clinical case report presents the surgical orthodontic treatment of an adult patient with deep overbite and skeletal Class Ⅱ discrepancy. She had a hypodivergent facial pattern, impacted maxillary canine, and traumatic deep bite due to the overeruption of the mandibular anterior teeth. The deep bite was corrected by bialveolar anterior segment osteotomy dramatically. The posttreatment occlusion was significantly improved, with stable interincisal angle and contacts.
