ABSTRACT:
An improved tray 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 and a second tray are provided, each tray including a base surface, first and second spaced apart and upwardly extending side walls and first and second end walls. The side walls are each defined by pluralities of spaced apart and vertically extending raised portions which permit segmented portions of the upper and lower dental models to be releasably attachable in correct position. The articulator includes a first mounting portion extending from the first tray and a second identically shaped mounting portion extending from the second tray. A first insert portion engages the first mounting portion and a second insert portion engages the second mounting portion. The first and second insert portions are each adjustable in height relative to their associated trays and further include aligning eyelet portions which permit them to be hingedly secured along a common axis so as to provide for desired positioning of the opposingly arrayed dental models.
