Occlusal contact on the side opposite the direction of mandibular movement is called which side?

Explanation:
When the mandible moves laterally, it travels toward one side, which is the working side. The side opposite that movement is known as the non-working side (balancing side). Occlusal contact on this opposite side is what the question is asking about, so the correct term is the non-working side. The Curve of Spee and Curve of Wilson describe the overall curvature of the occlusal surfaces in sagittal and frontal planes, not the side of contact relative to movement, so they don’t fit here.
