ABSTRACT:
Styluses defining a hinge axis in a dental articulator are received in guide block pathways defined by side walls and a curved upper wall. The blocks are rotatably mounted to vary the slope of the upper wall. A supply of guide blocks is provided having a medial wall with a rear curved portion which varies for different blocks based on average values. The user selects the blocks having the desired medial wall to provide the desired side shift. In one arrangement, the side walls are formed as a unit and removeably mounted on the upper wall and the user selects the side wall unit from a supply of units providing different degrees of side shift movement. In another form, the medial wall is transversely adjustable.
