<p>Denture product and forming system for denture products comprising tooth structure and a supporting base, including: a fluid, two-component thermosetting resin supply (70) having a mixer for mixing a resin reactive mixture from the components and an injection outlet (84) from the mixer; a denture mold (28) comprising a closed cavity (68) having an inlet for receiving delivery of the resin reactive mixture from the supply under injection pressure and at a predetermined cavity filling flow rate; and spaced from the inlet a vent (86, 88) adapted for venting gases from the cavity while blocking resin reactive mixture from emptying from the cavity at greater than a predetermined cavity emptying flow rate which is less than the cavity filling flow rate, so that the resin reactive mixture overfills the cavity and self-pressurizes to a pressure sufficient to block any incorporated gases in the resin reactive mixture from forming voids or bubbles during curing.</p> |
