The ANB angle for Class II compared to Class I is

Greater
Smaller
The same
Not comparable

The correct answer is: Greater

Class II refers to a dental classification of malocclusion where the upper first molar is positioned anteriorly (more forward) compared to the lower first molar. Class I, on the other hand, is the normal or healthy alignment of the upper and lower molars. The ANB angle is a measurement used to determine the relationship between the upper and lower jaws. In Class II malocclusion, the ANB angle will be greater than that of Class I due to the more anterior position of the upper jaw. Option B is incorrect as a Class II malocclusion would result in a greater ANB angle, not a smaller one. Option C is also incorrect as the ANB angle is specifically used to compare Class II and Class I malocclusions. Option D is not a relevant answer as the ANB angle is used as a comparison between two specific classes of malocclusions.
