<p>A dental device is provided for fabricating dies from flexible impression material wherein the model, die and articulation mounting are accomplished in a single pouring. The device comprises a pair of recessed pivotal trays generally shaped to an individual's jaw. The member each includes inner and outer walls having internal ridges running vertically therealong at spaced distances and a base having predetermined spaced apertures thereabout to receive an insert. The trays are designed to be mounted face to face with a like member and open to 180 DEG . The tray includes hollow cylindrical portions in the rear thereof, engaged by a transverse element for pivoting thereabout. A vertical stop pin is mounted through the distal arm to maintain the respective spacing of the trays. The insert member has downwardly projecting portions extending through the base apertures, a base engaging the base of the tray and an upwardly extending rib which is located centrally within the walls of the tray. The projecting portions of the plastic member may be pushed vertically to readily eject the mold from the articulator after it has hardened. The mold may be sectioned so that it is possible to remove and accurately replace sections individually.</p> |
