A clamp device and method for restraining a hinge joint of a model articulator to single axis vertical hinging motion is disclosed. The hinge joint comprises outwardly facing convexities restrained between elements that incorporate detents to mate with the convexities, the hinging action of the joint provided for by the rotation of the convexities while captured between the detents. The hinge joint further permits functional masticatory protrusive and lateral motions of the dental models articulated by the joint by allowing sliding motion of the convexities outside of the centric position of the detents. The clamp device placed around the joint prevents splaying of the elements of the joint, thereby limiting the functional motions of the joint thus and forcing the joint to a strictly hinging action.
