The effects of miniscrew with Class III traction in growing patients with maxillary deficiency.

The aim of this study was to compare the effects of face mask and miniscrew combined with Class III traction on Class III malocclusion maxillary deficiency in growing patients. 10 patients were treated with facemask and 10 other patients were treated by means of miniscrew and Class III traction. Pre- and post-treatment cephalometric data were analyzed and compared between the two groups. Both groups were successfully treated; however, IMPA increased in miniscrew group while it decreased in facemask group.
