| Abstract |
|
320 cephalometric roentgenograms of 25 boys and 15 girls which was longitudinally taken from the age 6.5 to 13.5 have been analyzed to access the angular growth changes of the mandible. The statistical analysis of the results allowed the following conclusions.
1. Gonial angle was reduced with ageing.
2. Chin angle was reduced with ageing.
3. Occlusal plane to mandibular plane angle was relatively stable.
4. Lower incisor to occlusal plane angle was reduced and showed the greatest variability. |
