Figure 3 Four facial components which can be varied in combination to achieve a Class 2 malocclusion are shown. Dark blue represents the skeletal component of the maxillary bone, light blue is the maxillary dentoalveolar component. Yellow represents the dentoalveolar component of the mandible and the green represents the skeletal component of the mandible. Examples of Class 2 malocclusion could be achieved by moving the dark blue or light blue or both in a ventral direction relative to a stationary yellow or green. Class 2 malocclusion could also be achieved by a dorsal positioned yellow or green or both relative to a stationary dark and light blue. It gets more interesting when you consider that the components can all be moved relative to each other because of relative plasticity of the dentoalveolar components to the basal skeletal components. Yellow could be moved dorsally relative to green or light blue could be moved ventral relative to dark blue. Cranial factors such as cranial base length are not considered here.
