Abstract

This investigation was designed to categorize Angle´s class III malocclusion groups through analyzing horizontal and vertical components of craniofacial skeleton in Angle´s class III malocclusion. The material selected for this study consisted in standard lateral cephalogram of one hundred and fifty five children, seventy four boys and eighty one girls, aged 6 through 15 years_ having Angle´s class III malocclusion.
On the basis of findings of this study, the following results were obtained.
1. In horizontal skeletal classifications, 16 groups were classified FMN-A-B. SE-FMN A according to the Ba-SE-Me, Ba-SE/R.
2. The sequences that have relatively high frequency are as follow;
a) Horizontal Group 1 b) Horizontal Group 3
c) Horizontal Group 5 d) Horizontal Group 9 e) Horizontal Group 4
3. In vertical skeletal classification, 8 groups were classified according to the PMV/PP, PMV/OP. PMV/MP.
4. The sequences that relatively high are as follows;
a) Vertical Group I b) Vertical Group 3
c) Vertical Grou p4 d) Vertical Group 8
