The curve of Spee is greatest in which malocclusion relationship?

Class I
Class II
Class III
None

The correct answer is: Class II

This is because in Class II malocclusion, the lower jaw is positioned further back compared to the upper jaw, creating a steeper curve of Spee. In Class I, the lower jaw is in a more ideal position, resulting in a less prominent curve of Spee. In Class III malocclusion, the lower jaw is positioned forward, resulting in a flatter curve of Spee. Option D, "None", is incorrect because the curve of Spee is present in all individuals regardless of their malocclusion relationship.
