ABSTRACT:
A dental articulator has a generally flat fixed base and a pivoted top with trays mounted on both the base and top. The trays have upstanding side wall elements, each tray being dimensioned and spaced for reception of a hard mold member having a generally flat top surface mounting a positive cast or dental model of one of a patient's arches. The peripheral edge portions of the hard mold members are dimensioned to be press fitted into the trays to abut juxtaposed ones of side wall elements of the tray. The trays are each slidable in Y or X-y axes with respect to substages connected to the articulator top and articulator base, respectively. Each tray has a straight rear wall, with the remainder of a continuous wall being in straight or curved interior segments. In one embodiment, a series of posts define the internal periphery of the trays.
