Cusp-fossa occlusal scheme is seen with class ____.

The correct answer is: 2

The cusp-fossa occlusal scheme is a specific type of occlusal relationship between the upper and lower teeth in a dental class II relationship. This means that the occlusal relationship between the molars is characterized by the presence of mesial cusps on the lower molars fitting into distal fossae of the upper molars. This specific occlusal scheme is seen in class II relationships as it reflects the buccal-lingual position of the upper and lower teeth in this type of relationship. In class I and class III occlusal relationships, different occlusal schemes may be seen, such as cusp-to-cusp or lingual-to-lingual. Therefore, the correct answer for the class in which cusp-fossa occlusal scheme is seen is option B class II. Options A, C, and D are incorrect as they do not correspond to the correct type of occlusal scheme or class relationship.
