A review of the management of anterior open bite malocclusion.
Anterior openbite (AOB) malocclusion is considered one of the most demanding challenges for the orthodontist, as occlusal correction is difficult, facial aesthetics may be unsatisfactory and the incidence of relapse is high. A retrospective cephalometric study of 19 consecutively treated AOB patients is presented. The follow-up ranged from 12 to 48 months. Several case reports are included to demonstrate a contemporary approach combining orthodontic treatment and orthognathic surgery. The results indicate that overbite was maintained with good vertical skeletal stability. Anteroposterior position was less stable. Posterior facial height was maintained or decreased, and there was no evidence of postsurgical maxillary incisor movement. It is concluded that occlusal stability and clinical success may be anticipated when certain criteria are adhered to in all phases of treatment, and that a coordinated surgical-orthodontic treatment approach currently offers the best chance of attaining occlusal stability, improved function and satisfactory aesthetics.
