Final answer:
Class II occlusion, also known as a Distoclusion, involves an overbite where the upper teeth protrude beyond the lower teeth due to the positioning of the molars.
Step-by-step explanation:
Class II occlusion is also known as B) Distoclusion. This type of occlusion occurs when the lower first molar is positioned more towards the back of the mouth compared to the upper first molar, creating an overbite situation where the upper jaw or teeth protrude beyond the lower jaw or teeth. In contrast, Class I occlusion would be a normal relationship and Class III, referred to as Mesioclusion, is when the lower first molar is more towards the front of the mouth in relation to the upper molar, often resulting in an underbite.
