A dental articulator (10) has a generally flat fixed base (11) and a pivoted top (14) with trays (26, 24) mounted on both the base and top. The trays have upstanding sidewall elements (28), 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 sidewall elements of the tray. The trays are each slidable in Y, or X-Y axes with respect to sub stages connected to the articulator top and articulator base, respectively. Each tray has a straight rear wall (29), 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.
