영문 초록

This purpose of this study was to investigate the differences in soft tissue characteristrcs according to the dental or skeletal dysplasia. For this purpose, lateral cephalogram of 153 children (Hellman dental age IIIB, control group 32, Angle Cl II. Div 1 malocclusion group 55, Angle Cl III group 66) were traced and measured. For these measurements, following conclusions were made. 1. FH A, FH Sn, FH UL, AA’ of the Class III group were thicker than those of the normal and Class II group, but FH B, FH LL’, BB’ of the Class III group were not significantly different from those of the normal group. 2. FH B, FH LL, BB’ of the Class II group were thicker than those of the normal and Class III group, but FH A, FH Sn, FH UL, AA’ of the Class II group were not significantly different from those of the normal group. 3. Ans-Sn, FH P were not significantly different in three groups, while pp’ of the Class III group was thicker than those of the other groups. 4. The lower lips of the Class II group were more anterioly everted with respect to the lower incisor inclination than those of the other groups. 5. The severity of skeletal dysplasia was partly camouflaged by the soft tissue.
