A STUDY ABOUT CLINICAL APPLICATION OF GROWTH CHANGES IN SAGITTAL JAW RELATION AND INCISOR POSITION

상하악 전돌상태와 상하악전치위치의 성장변화에 대한 임상적 응용에 관한 연구

The growth changes in position of upper and lower jaws, incisal inclination in relation to inferior cranial base have been described. Twenty five males was studied quantitavely by means of serial cephalometric reontgenogram from seven to thirteen years of age. The findings seem to warrant the following conclusions: 1. Growth change in anteroposterior relationship of upper and lower jaws to the anterior cranial base showed very little change before eleven years of age but axial inclination of incisal teeth tended to become labiaization in relation to the anterior cranial base. 2. kiter eleven years of age, there wasn't nearly labialization of incisal teeth but jaw prognathism occurred a little in relation to the anterior cranial base.
