GROWTH OF MANDIBULAR PROGNATHISM AFTER PUBERTAL GROWTH PEAK

This study deals with the growth changes of the Japanese face associat ed with mandibular prognathism during 3 years after the pubertal growt h peak. The investigation was based on the serial lateral cephalometri c roentgenograms of prognathic and normal males and females, respectiv ely. Maturational stages of the pubertal growth were determined indivi dually by the ossification events taken from hand-wrist radiographs. R esults indicate that the morphologic characteristics of the mandibular prognathism, which are established before the pubertal growth peak, a re strongly maintained during the period studied. However, mandibular prognathism seems to show a manner of growth change fairly similar to that of the normal after the pubertal growth peak.
