This study was performed to compare the pattern of dentoalveolar characteristics in different´ vertical and anteroposterior skeletal types in-skeletal Classl l malocclusion.
The samples selected for this study were consisted of 60 subjects(29 males and 31 females, mean age; 19.7 years) in Class III group, 43 subjects(14males and 29 females, mean age : 20.5 years) in normal group.
The findings of this study were as follows ;
1. The 1MPA of the Class III group was smaller than that of the Class I group(p<0.01).
2. In the Class III groups, SNB and NtoPog had negative correlation with IM.PA(p<0.01). The SNB and NtoPog had
correlations with SNU1, FHU1 and Pa1U1(p<0.01) in the male samples, and in the female samples, the SNB and
NtoPog had correlation with SNU1(p<0.01).
3. In the Class III male samples, SNMP, FMA, PaIMP had negative correlation with IMPA(p<0.01). SNMP, FAA, PaIMP had not significant correlation with SNU1, FHU1, PalU1. In the Class III female samples, FMA, PaIMP had negative correlation with IMPA(p<0.01).
4. In the high angle group of Class Ill samples, SNU1, IIVIPA is smaller than that of low angle group of Class III samples(p<0.05).
