A dental cast tray assembly (11) used to retain a dental cast model comprises a base (13) and a tray (15) removably mounted on the base. An elongated, tubular projection (49) is formed onto the top surface (17) of the base. A plurality of stabilizing pins (60) are formed onto and extend away from the tubular projection. An elongated socket (101) is formed onto the bottom surface (63) of the tray. The socket is shaped to define an opening into which the projection is capable of being releasably press-fit. The socket is also shaped to define a plurality of holes (104) which are shaped to fittingly receive the stabilizing pins. The top surface (61) of the tray is recessed so as to form an enclosed reservoir (73) for holding the dental cast model. A plurality of spaced apart retention walls (77) are formed within the enclosed reservoir for permanently retaining the dental cast model onto the tray.
