ABSTRACT:
A dental articulator with its condyle joint being a single ball attached to the upper support member and being removable as well as rotatable through 360 degrees, with the ball being supported in a spring loaded cylinder, allowing the technician to position the upper support member in multiple positions without the need of locking screws. Also, the incisal guide pin is located behind the models to give an unobstructed work area and a unique retaining method is provided which leaves an imprint on the plaster mold so that the molds can only be replaced in one position.
