ABSTRACT OF THE DISCLOSURE A dental die tray assembly for the production of a dental working model for use in producing a prosthetic dental device, the assembly including a die tray body mem- ber having upper and lower surfaces, and a peripheral outer wall. A hollow arcuate mold cavity extends entirely through the body member in an outwardly widening direction from the lower surface to the upper surface. The mold cavity is bounded by facing outer and inner walls, with the outer cavity wall being foreshortened by a recessed seat bounding an outer periphery of the mold cavity. Continuous teeth are disposed on the facing cavity walls and extend into the mold cavity. A pair of removable arms are pivot- ally coupled to respective side portions of the peripheral outer wall of the die tray body member and embrace at least a portion of the body member circumscribing the mold cavity to releasably hold the model in the mold cavity. A rever- sible base plate member includes a substantially flat base surface on one side thereof which serves as a bottom for the mold cavity during the formation of the model, and further includes pusher members protruding from the opposite side thereof for ejecting the model from the mold cavity after the model has been completed. -27-
