摘要： A dental articulator is disclosed which simulates the operation of human jaws for use in the manufacture of false teeth. An upper frame representing the upper jaw is mounted to a lower frame by a pair of ball and socket joints which may be adjusted to approximate a specific patient''s jaw hinge. Each socket has three sides. Relative motion of the ball is allowed along two sides of the socket and away from the third side. The third side provides a reference position corresponding to the fully closed, occludent position of the upper and lower jaws. The two sides which determine the direction of allowed motion of the ball relative to the socket may be adjusted independently as to azimuth and elevation without disturbing the fixed reference position. Further, a lock arrangement is provided which locks each ball in the fixed reference position while allowing rotation of the upper frame and sockets about that position.
