Abstract

To predict the pubertal growth peak in stature and study the skeletal maturity degree using hand-wrist radiograph, the author used the 70 malocclusions (male 24, female 46). After longitudinal measurement of stature and skeletal maturity indicators of hand-wrist radiographs were taken during 4 years, the rsults were as follows. 1) The pubertal growth peak in stature occurred mainly at SMI 6-7 (56.5%) in female, SMI 5-6 (37.5%), 6-7 (37.5%) in male (Table 5). 2) It was suggested that the pubertal growth peak in stature was already passed, if SMI 8 occurred. 3) Ages of SMI in female were about 2 years earlier than those of SMI in male, and the sexual difference was gradually decreased in puberty. 4) Duration of SMI was longest at SMI 6-7 in both sex and the mean was 8.5 months. After this stage, the velocity of skeletal maturity in female was decreased than in male. 5) The correlation coefficient between each SMI and pubertal growth peak was very high (Table 8).
