Miniimplant had controlled vertical face by adjusting the vertical positions of the molars and the incisors made rotation mandibular and changed lower facial height (with hypodivergent group the molars were emergented, incisors were intrusived so GoGnSn increased, ANS-Me increased; with hyperdivergent group the molars were intrusived and incisors were uprighted so GoGnSN decreased, ANS-Me decreased, with normodivergent group the vertical positions of the molars and the incisors changed a litte, and GoGnSN, ANS-Me had no significant differences were observed in the pre-treatment and the posttreatment skeletal measurements.
