Bioprogressive Therapy에 의한 Angle II급 1류 부정교합의 교정치험예

Three patients who had Angle's Class II Division 1 malocclusion were treated by Bioprogressive therapy. In spite of their occlusions, the 3 patients did not have any skeletal problems. Their skeletal patterns were within normal range. So headgear or functional appliance therapy were not considered. During the treatment procedure, the most noteworthy results of Bioprogressive therapy were the effect of the Utility arch to intrude 4 mandibular anterior teeth, the effect of the Cuspid retractor in cuspid retraction and the effect of the Double delta retraction arch in the retraction of 4 anterior teeth. The whole treatment results in these cases which were achieved by Bioprogressive therapy were very favorable and the efficiency of this therapy was very excellent.
