There exists racial distinctives in accordance with the configuration of craniofacial
complecx and the configuration differs with the structural feature related to the
malocclusion. Within the same malocclusion groups of the identical racial species, the
different features of facial configureration also exist by the co-relation, location and size
of the structures.
Therefore, it is requested to pay a careful attention for the diagnosis and treatment
planning.
This study was performed to classify the configuration of the craniofacial skeleton of
the growing korean children who had the Angle's Class ¥² malocclusion with.
In odder to get the configurational classification, 73 children's cephalometric radiographs
had been measured with the Enlow's Counterpart Analysis, and statistical approach
reached the following results by classifying the variables.
The followings are summerized results.
1. Structural aggregate effects consisting each type of the craniofacial skeleton was
forming mandibular protrusion, but it showed respective partial characteristics.
2. Ground samples had been classified to type A(22 children), type B(28 children) and
type C(23 children) by the statistical approach.
3. Type A represented a severe mandibula¥ã protrusion effect In alignment of the
middle cranial fossa. This type showed the short middle and low facial length, while
representing the ramus alignment and width were weakening mandibular protrusion
effect (Brachycephalic trend Glass ¥² malocclusion).
4. Type B represented neutral effect in alignment of the middle cranial fossa. This type
showed short middle and long low facial length, while representing the ramus alignment
and width severing mandibular protrusion effect (Mesocephalic trend Class ¥²
malocclusion).
5. Type C represented A most severe maxillary protrusion effect In alignment of the
middle cranial fossa and ramus alignment. This type showed long middle and shoot low
facial length, while representing a most severe protrusion effect in the ramps width and
dentoalveolar legion (Dolichocephalic trend Class ¥² malocclusion).
