ABSTRACT

The Cephalometric Roentgenograms of 20 individuals (10 male, 10 female) with Class III anomaly and 20 individuals (10 male, 10 female) with normal occlusion are investigated by McNamara Analysis and the stages of developments are evaluated by the hand -wrist roentgenograms. In this study, the difference between the normal and anomaly groups and also the difference between the male and female are investigated. And it is also investigated, if the difference between male and female in the normal group also exists in the anomaly group and the difference for the female between normal and anomaly groups, and the difference for the male is conserved between normal and anomaly groups and in addition, the face skeletal part which is responsible from the development of this anomaly.
