Abstract

This investigation was designed to categorize Angle´s class II malocclusion groups through analyzing horizontal and vertical components of craniofacial skeleton in Angle´s class II malocclusion. The material selected for this study consisted in standard lateral cephalogram of two hundred and twenteen children, eighty eight boys and one hundred twenty four girls, aged 6 through 18 years, having Angle´s class II malocclusion.
On the basis of findings of this study, the following results were obtained.
1. In horizontal skeletal classifications, 16 groups were classified according to FMN-A-B, SEFMN-A, Ba SE-Me, Ba-Se/Ra P. The sequences that have relatively high frequency are as follows: ?
a) Horizontal Group 16 b) Horizontal Group 12
c) Horizontal Group 13 d) Horizontal Group 9 & 15
2. In vertical skeletal classification, 8 groups were classified according to the PMV/PP, PMV/ Occ. P. PMV/Mn. P. The sequences that relatively high frequency are as follows; a) Vertical Group A b) Vertical Group D
c) Vertical Group C d) Vertical Group H
3. In vertical and horizontal skeletal classifications, the sequence that relatively high frequency are as follows;
a) Group 13-A b) Group 16-A & 9-A
c) Group 12-A & 15-A d) Group 16-C
