CEPHALOMETRIC ANALYSIS OF MAXILLOFACIAL NORMALS IN KOREAN ADULTS

This study was performed to aid for the case analysis and diagnosis of the maxillofacial deformities. A cephalometric analysis was made form 101 subjects over 18 years old, that consisted of 46 males and 55 females with normal occlusion, acceptable profile. The results of this study were obtained as follows: 1. The tables of normals in adult male and female were made. 2. The angles of SNO were 65.5° in male and 65.3° in female and the horizontal linear measureaments from 0 to NA(O-NA) were 9.0mm in male and 8.9mm in female. 3. The cranial base angles (SN-FH) were 8.2° in male and 10.3° in female and the mandibular plane angles (OP-HP) were 28.1° in male and 26.2 in female. 4. The correlation of (O-NA) to S-O/S-A and S-O/S-N were higher than SNO, and the correlation of (N-A) to SNA and (N-B) were high.
