We investigated morphological characteristics in the craniofacial complex of adult Japanese by carrying out Enlow's counterpart analysis on 100 cephalograms each of selected Class I, Class II, and Class III malocclusion cases. Classes I and II were classified as either type A or B depending on whether point A or B was protrusive in the functional occlusal plane. We found that the craniofacial patterns of the B group were different from the A group, and that both Class I A and B had a Class II tendency. Compensatory effects generally failed in the Class II type A and Class III groups. However, a composite compensatory result was produced in the Class I type B group. Both Class I type B and Class II type B had an underlying Class III character in many regional anatomical relationships. These characteristic features may be the basis for the higher incidence of Class III type malocclusions in Japanese.
