Image Number 17 for United States Patent #6511318.
A dental modeling system includes a pair of supports for opposing dental casts which are articulated together by a pair of pivotally connected articulator arms. The support may include a plurality of integral registration pins extending from a top surface thereof which provide superior registration of a dental casts located thereon. The support may be directly attached to the articulator arm, or may be attached via a ball-and-socket joint, which, once located in the proper position, is glued in place. The articulator arm permits the castings to move toward and away from one another, and permits the replication of centric, excursive, and protrusive movements of the jaw. An alternative support for a dental cast includes a back member and a bottom member oriented at approximately 90.degree. with respect to one another to form an L-shaped main body, onto which a dental cast may be attached.
