영문 초록

This study was designed to investigate the variation of mandibular pattern and cranial base and their association in the craniofacial malocclusion. The material was the 165 cephalometric radiographs taken from craniofacial malocclusion. The sample was devided into two groups by age child group aged from 10 to 13 years and adult group aged over 18 years, and each group was devided into 3 types of malocclusion, class I, Class II div. 1 and Class III malocclusion. Child group consist of 35 samples and adult group consist of 20 samples in each malocclusion type. Various angular and linear measurements on the cephalometric radiographs were recorded and statistically analyzed. The results of the study were as follows, 1. The cranial base angle was largest in Class II div, 1 malocclusion and smallest in Class III malocclusion 2. The anterior cranial base length was largest in Class II div 1 malocclusion but posterior cranial base length did not show statistical difference 3. The mandibular body length of Class III malocclusion was larger than those of Class I and Class II div 1 malocclusion in the adult group but did not shown difference in the child group. The ramus height of Class III malocclusion was larger than those of Class I and Class II div 1 malocclusion in the child and adult group, but there were no difference between Class I and Class II div, 1 malocclusion. 4. The mandibular position was showed low correlation with the cranial base angele.
