Abstract
A system and method is disclosed for obtaining precisely registered, articulated castings of upper and lower dental impressions. The dental impressions are obtained through use of a dental tray. The tray has an upper and a lower section, each having a non-porous, bite-deformable central septum. Each tray section has a U-shaped peripheral wall. The tray sections are placed back-to-back so that the septums are in movable contact with each other. Means are provided to maintain the upper and lower tray sections in position with respect to each other once they have been adjusted. A cavity is formed in the upper or lower tray section, or both, adjacent to the anterior portion of the peripheral retaining wall. The cavity extends past the dividing septums to accommodate gross overbite and/or underbite conditions.
