In the temporomandibular joint, there are two kinds of movements: rotation and translation.  

Rotation is the movement around an axis. It is the movement of an object around its axes.

The mandibular rotation movement occurs in the condyles and might be produced in three planes: horizontal plane, frontal, and sagittal planes.

- Horizontal Plane:  These are lateral movements together with back and foward movements.  

- Frontal: Involves up/down, and lateral movements.
