ABSTRACT:
A dental articulator having upper and lower mounting plates for supporting upper and lower models of teeth, the upper mounting plate being supported in fixed relation to a base-plate and frame, and the lower mounting plate being movable in a substantially horizontal plane about a centric position with respect to the upper mounting plate, to simulate corresponding movements of a patient's lower jaw. A pair of lower articulating elements attached to the lower mounting plate are held magnetically in engagement with a pair of upper articulating elements on the frame, the upper and lower articulating elements being patterned after the fossae and condyles, respectively, of a human mandibular joint, and being adjustable in lateral spacing and angular orientation to closely simulate the movements of a particular patient's jaws.
