Treatment of marked anteroposterior and transverse discrepancies in mandibular prognathism.

A case report of a patient with a severe skeletal Class III malocclusion has been presented. The patient's marked anteroposterior discrepancy was complicated by the fact that his buccolingual occlusion was normal. The solution to this case thus involved a correction of the transverse discrepancy in addition to the anteroposterior discrepancy, which required orthodontic and surgical solutions. A discussion of mandibular prognathism has also been presented.
