ABSTRACT:
A dental jaw simulator is provided for duplicating human jaw movements and, in particular, the movement of the lower human jaw. The simulator includes a support frame and an upper jaw member pivotally mounted on the support frame and which is adapted to receive an upper dental arch cast. A lower jaw member is also mounted on the support frame and is adapted to receive a lower dental arch cast. Movement of the lower jaw member in protrusive and retrusive directions and in a lateral direction is controlled by a ball and slot hinge arrangement in combination with a movable anterior platform mounted on the support frame and a forward pin connected to the lower jaw member and which engages and is movable relative to the anterior platform. The anterior platform is provided with sloping planes on which the forward pin moves to guide the lower jaw member in order to duplicate the dropping of the lower human jaw during lateral movement.
