Abstract
Growth changes in skeletal facial profile were studied by analyzing serial cephalometric roentgenograms of forty persons who were grouped according to sex and occlusion. Four linear and four angular dimensions were measured. There were basic differences in the growth patterns of linear and angular dimensions. The linear dimensions showed puberal acceleration. In boys, greater forward growth was noticed in the lower face during the puberal period, making their faces more straight, square, and angular. The girls had rounded faces with slightly convex facial profiles. The group with normal occlusion was found to have a greater downward and forward growth pattern than the group with Class I malocclusion. The findings indicated that puberal growth changes in the face should be anticipated according to the sex of an individual. The faces of persons with malocclusion were more protrusive than those of persons with normal occlusion. The results of this study have a significant bearing on the clinical aspects of orthodontic practice. As has been observed, illustrated, and discussed in this article, no standard norm can be rigidly used to assess the growth pattern of an individual, as individual variation in skeletal growth is a normal occurrence.
