The classification is given by:
Correct Answer: Both 1 and 2
Description: Figure shows a Venn diagram; Ackerman and Proffit represented the five major characteristics of malocclusion via a Venn diagram.
The sequential description of the major characteristics, not their graphic representation, is the key to this classification system, but the interaction of the tooth and jaw relationships with facial appearance must be kept in mind.
Note that for each characteristic, the items to be evaluated are listed within the box or circle, with a spectrum of potential problems within that area represented by opposing terms (spacing ,crowding, symmetry and asymmetry) and items to be evaluated for dentofacial appearance appear separately in the lower part of that field.
The circle for each plane of space represents not only the position, but also the orientation of jaws and teeth in that plane of space, and the overlaps between the circles representing the three planes of space are labeled for the orientation problem that this interaction could represent.
