Abstract:
Objective:To evaluate the linearity change of hard tissue of the juvenile of Class II division 1 with mandible functional retrusion by IMGA. Methods: The pre- and post- treatment cephalometric of 12 juvenile patients with IMGA were analyzed in Pancherz analysis to compare the dental position and the skeletal change. Results: After treatment, as far as OLp plane, the statistical changes were significance by pg/OLp,mi/OLp,ii/OLp, co/OLp +pg/OLp,is/OLp -ii/OLp,ms/OLp -mi/OLp,is/OLp-ss/OLp(P0.05), respectively. Conclusion: The IMGA is effective on the treatment of the juvenile patients of Class II division 1 with mandible retrusion of facial hypodivergency.
