Abstract:
A dental model articulator for joining upper and lower dental models, the articulator comprising:an arm comprising first and second arm segments, each having a proximal end and a distal end, and an intermediate hinge joint for joining the proximal ends of the first and second arm segments to provide hinging motion about a hinge axis, each arm segment connected at its distal end to one of the upper and lower dental models, the hinge joint further having an amount of orthogonal deviation from the hinge axis that provides multiaxial motion, the hinge joint comprises a node and a retaining element for receiving the node therebetween, the node being attached to the proximal end of the first arm segment and the retaining element being attached to the proximal end of the second arm segment, the joint including resilient compression means for restraining the node in the retaining element to limit and allow a free range of action of the hinge joint.
