Correction of skeletal Class II malocclusions with deep bite by rapid extrusion of posterior teeth

Abstract

Patients with skeletal Class II malocclusions and deep bites can be difficult to manage properly. Dental compensations, mandibular retrognathia, vertical dysplasia of inadequate posterior alveolar growth, and compensating chin effects must be considered if one is to achieve ideal treatment results. The eleven cases presented were managed through a combination of surgery, orthodontics, and rapid extrusion of the posterior dental arches. The rapid extrusion process is begun during the surgical healing phase, thereby decreasing total treatment time. Other advantages include simplicity of the surgical procedure, acceptance by the patient, stability of the facial and dental results, and possible avoidance of additional chin surgery.
