Report of a patient with a Class II occlusion using the Begg technique to move the first molars distally.

A 14-year-old female with a Class II occlusion and an increased overbite was treated using a Begg appliance and a modified Henrikson's arch. The treatment resulted in a Class I occlusion and ideal overjet, overbite, and incisor angulation. Class I occlusion was achieved after 6 months, and total treatment time was 1 year 6 months. The Begg technique with intermaxillary traction to move posterior teeth distally is an effective method to correct a Class II occlusion with minimum mandibular crowding.
