<p>This invention is a system, and articulator for use with a replication of a dental patient's teeth taken by a conventional dental impression in the creation of a dental model of the patient's mouth. A first tray (18), and a second tray (20) are provided, each tray including a base surface (22) having at least one frangible portion (56) formed therewith; first, and second spaced apart; upwardly extending side walls (24, 26); and first, and second end walls (28, 30) which define a recessed cavity therebetween. The side walls are each defined by pluralities of spaced apart, vertically extending raised portions (46, 48) which permit segmented portions of the upper, and lower dental models to be releasably attachable in correct position. A template base (62) is provided with a configuration suitable for supporting an underside of each of said trays in an upright fashion that includes at least one raised portion (70) corresponding in location, and placement with the at least one frangible portion. A punch member (72) is configured to engage first, and second selected surfaces of each of the trays that downwardly actuates the trays so that the frangible portions are forcibly disengaged from the base surface. The base layer of stone, and associated dental model are ejected from within the recessed cavity.</p> |
