Although there is a severe underlying skeletal deformity, the dentition has often
maintained some occlusal contact and interdigitation by the teeth compensating in their
positions for the skeletal problem, and these dental compensations are manifested in all
three planes of space. The purposes of present investigation were 1) to study the
pattern of dentoalveolar compensation of hyperdivergent skeletal pattern : and 2) to
compare the centoalveolar compensations of hyperdivergent skeletal pattern in children
with adults. The samples selected for this study were consisted of 60 subjects in normal
group, 60 subjects in hperdivergent group. each was divided into two subgroups by age
; child groups(8¡­12yr old) and adult groups(17yr old over).
The findings of this study were as follows;
1. In child, hyperdivergent subjects had smaller posterior lower facial height(p£¼0.01) and
slightly longer anterior lower facial height than normal ones. In adults, they still
expressed smaller posterior lower facial height and much longer anterior lower facial
height than normal ones(p£¼0.01).
2. Hyperdivergent subjects had larger amount of upper and lower incisor relative
eruption to their basal bone length than normal ones(p£¼0.05). In adult, relative eruption
of upper incisor was increasing(p£¼0.05), although relative eruption of lower incisor
remained the same as the child.
3. In child, there was no difference between hyperdivergent group and normal one in the
upper and lower molar relative eruption to their basal bone length. In adult,
hyperdivergent group had larger amount of upper molar relative eruption than normal
ones(p£¼0.01), but relative eruption of lower molar was similar to normal ones.
4. hyperdivergent group had larger angle between lower occlusal plane and mandibular
plane than normal group(p£¼0.01). Upper occlusal plane of adult group rotated more
antero-superiorly than child groups, and adult hyperdivergent group had steeper upper
occlusal plane than normal group(p£¼0.05).
