This study was performed to establish the cephalometric standards and to compare
measurement of Korean children in the Field ¥°, ¥±, ¥², ¥³, ¥´, ¥µ to Japanese and
Caucasians by the Ricketts¡¯ analysis. Lateral cephalograms of 24 males and 27 females
with normal occlusion and acceptable profile 9 years of age were obtained and
statistically analyzed.
1. Norms of Korean males, females and both sexes at 9 years old were established.
2. Significant differences between male and female exist in incisor overjet, maxillary
incisor protrusion, mandibular incisor inclination, cranial deflection, corpus length.
Maxillary incisor of male was more protrude and overjet was larger than female
3. Korean was similar to Japanese but different from Caucasian. Compare with facial
axis and facial depth, chin was retruded dolichofacial pattern and due to large
mandibular plane angle and small corpus length, mandibular plane was inclined and
mandible body was short. Compare with porion location, ramus position and posterior
facial height, ramus was long and located posterior. Compare with maxillary depth and
maxillary height, maxilla was located posterior and inferior. The distance between the
upper molar and PTV was short, the amount of distalization is limited. Maxillary and
mandibular incisor were more protruded and also lower lip was more protruded to
esthetic line
4. In comparison between 9 and 11 years old, growth changes of facial depth,
mandibular plane angle, corpus length and upper molar position were larger than that of
Japanese and Caucasians.
