|
|
This study was performed to establish the Cephalometric standards of Korean adults by McNamara analysis.
A cephalometric analysis was made from 103 subjects over 20 years of age, that consisted of 51 males and 52 females with normal occlusion and acceptable profile.
The results of this study were obtained as follows :
1. Distribution from measured values were obtatined.
2. Greater measurements were shown in male than in female in Effective Mandibular Length(EML), Effective Midfacial Length(EMiL), Maxillo-mandibular differential(Mx-Mn diff) and Lower anterior facial height (LAFH) in linear measurement of each group.
3. Mandibular plane angle of female was larger than that of male. It represents female has more dolichocephalic pattern.
4. Facial axis angle of korean adult was greater than that of Ann Arbor sample. It means Gnathion of Korean adult is located more posteriorly than that of Ann Arbor sample.
