Correction of mandibular dentoalveolar retrusion by anterior segmental advancement

Mandibular anterior segmental advancement offers an alternative mode of management for certain patients with Class II dentoalveolar malocclusion. The procedure is ideally indicted in paradoxical occlusal situations wherein Class II malocclusion is associated with a prognathic profile or when total body advancement would produce an unacceptable occlusion or profile. Arch expansion and augmentation genioplasty may be achieved by tailoring the surgical approach. Complications were minimal in the cases presented. Since arch lengthening results, the potential food table is increased, necessitating either fixed or removeable prosthetic care.
