영문 초록

The purposes of the present study were to describe the vertical and anteroposterior facial dysplasia, and to identify morphologic differences associated with various facial patterns. Anteroposterior dysplasia was classified by traditional Angle´s malocclusion classification and according to vertical relationships based on the SN-MP angle, facial pattern was subclassified to 3 vertical groups in each malocclusion group. Each vertical group composed of 20 samples and total 180 samples aged from 9 to 14 years. The results were as follows; 1. The skeletal differences that lead to disportionate lower facial height in vertical and anteroposterior facial dysplasia were closely related to mandibular morphology. 2. Hyperdivergent group, compared with hypodivergent group, demonstrated decrease of SNA and SNB and linguoversion of maxillary and mandibular central incisors in all malocclusion groups. 3. Irrespective of rotation of the jaws, Wits appraisal was a useful measurement in evaluation of relative anteroposterior relationship of maxilla and mandible. 4. As SN-MP angle increased, anterior facial height, especially lower anterior facial height, demonstrated significant increase and intermaxillary space also tended to increase. 5. The correlation coefficients of SN-MP angle and PTFH/ATFH demonstrated the highest value in all malocclusion groups.
