Growth and development evaluation of patients with growth potential is of great
importance for orthodontic treatment planning. Timing of orthodontic intervention greatly
depends on one's developmental status, thus if there is a difference in skeletal
maturation among malocclusion types different treatment timing should be applied.
The objective of this study was to evaluate and compare skeletal maturation among
different malocclusion types. The samples used in this study was 38 Class¥°. 36 Class¥±
and 33 Class¥² females aging from 8 to 10 years. Handwrist X-rays were taken with 6
month interval till 12-13 years of age. The results were as follows.
1. There was no skeletal maturity difference among different malocclusion types.
2. The hamular process of hamate was observed at 9.16¡¾0.72 years, pisiform bone at
9.13¡¾0.71 years and the ulnar sesamoid at 10.34¡¾0.84 years.
3. The timing of epiphyseal capping on the third finger was 10.96¡¾0.80 years for distal
phalanx and 11.27¡¾0.87 years for middle phalanx, 11.12¡¾0.86 years for proximal phalanx
of the first finger, 11.21¡¾0.82 years for radius and 11.62¡¾0.85 years for middle phalanx
of the fifth finger.
4. The appearance of pisiform bone showed high correlation with appearance of hamular
process of hamate(r=0.91), and ulnar sesamoid bone appearance showed high correlation
with advanced ossification of hamular process(r=0.86). Timing of epiphyseal capping
among different parts showed high correlation(r=0.80-0.90).
5. The shape of middle phalanx of the fifth finger showed the highest variability (20.
6£¥).
