This study was undertaken to investigate the growth change of gonial angle and
interrelationship between the growth change of gonial angle and IMPA in the
longitudinal data from 7 years to 15 years.
By analyzing the serial lateral cephalograms of 15 males and 18 females of 7 years
old to 15 years old who had no abnomality in growth and development and no history
of orthodontic treatment, the following conclusion were obtained.
1. Gonial angle gradually decreased with aging in 25 children and in 9 children increased
or maintained.
2. There was a tendency that children who decreased gonial angle with aging showed
gradual increase of IMPA and children who increased of maintained gonial angle with
aging showed decrease of IMPA
3. There was a tendency that regardless of the change of gonial angle, interincisal angle
decreased with aging.
