For a girl, aged 12 years 3 months, with a skeletal Class III malocclusion, negative overjet, severe maxillary crowding, and hyperdivergent pattern, orthognathic surgery combined with orthodontic treatment is often the treatment of choice, because it can greatly improve the patient's facial profile and ensure the long-term stability of the results. However, because of high risks and treatment expenses, patients sometimes refuse to have surgery. We report a nonsurgical combination therapy including facemask and multiloop edgewise archwires and the outcome for a patient with a developing skeletal Class III malocclusion and a long anterior facial height. Treatment included advancement of the maxilla by orthopedic means and counterclockwise rotation of the mandibular occlusal plane by the orthodontic dentoalveolar compensation of distal en-masse movement of the mandibular dentition.

D014716 Vertical Dimension The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (OVD or VDO) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (VDR) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position.
