Maximum opening, protrusive is what type of movement?

Rotation
Sliding/translation
Compression
Elevation

The correct answer is: Sliding/translation

Maximum opening, protrusive movement involves sliding/translation. When the mandible moves forward in a protrusive manner, it undergoes translational movement without rotation. This movement allows the mandible to move forward smoothly without any rotational component. Compression involves forces being directed towards each other, elevation refers to the upward movement of the mandible, and rotation involves movement around an axis.
