Tooth root shift in the vertical direction is called:

Explanation:
Vertical movement of a tooth into the bone is called intrusion. This moves the tooth along the vertical axis, with the root apex shifting in that direction, effectively intruding the tooth to reduce vertical dimensions and address issues like a deep bite or overeruption. The other terms don’t describe this vertical, apical movement: rotation is turning around the long axis; inclination refers to tilting; and extrusion is the opposite process, moving the tooth out of the socket in a vertical direction.
