ABSTRACT:
A dental model articulator includes two hinge-jointed arms, each arm having segments connected at a hinge joint having mating elements, one integral to each segment of an arm. One element includes two cymbals that are coaxial on a major hinge axis and concave facing which resiliently capture between them a node of the mating element on the other segment which has the form of opposed, outwardly facing convexities. Multiaxial motion between the segments of each arm is accommodated by the rotation of the convexities of the node within detents at the apices of the cymbals. The extremities of each arm terminate in cylindrical rod-like elements that are parallel to the major hinge axis. The rods engage with transverse, cylindrical channels either cut-in, molded-in or affixed to the models. With the models positioned in centric occlusal relationship and the arms adjacently positioned and engaged, the four rods are adhesively fixed in the channels. Once fixed, the two hinge joints together define a single hinge axis posterior and interjacent to the models. Further, each hinge joint can allow the node elements to release from the axis detents and slide between the cymbals to permit protrusive and lateral masticatory motions between the dental models.
