DEEP BITE를 동반한 골격형 제Ⅱ급 부정교합의 치험례

Treatment of skeletal class Ⅱ malocclusion with deep bite

Skeletal Class Ⅱ malocclusion with deep bite is difficult to manage properly. Generally the lower facial height is short and the curve of Spee is severe. We managed these cases as fellowe. 1) Tooth alignment through the pre-op. orthodontic treatment. 2) Surgically mandibular advanced with modified wafer. 3) Using the modified wafer, by rapid extrusion of posterior teeth, Curve of Spee was decreased during IMF. The rapid extrusion process is begun the IMF periods, thereby decreasing total treatment time. Our two cases result were satisfactory by means of more simple surgical technique and orthodontic treatment.
