ABSTRACT:
An apparatus and associated method for accurately producing an accurate impression of a patient's teeth. The apparatus includes an improved impression tray assembly that more accurately models the teeth. The impression tray includes a segment of curable material having a top edge, a bottom edge, a face surface and a rear surface, wherein the face surface and the rear surface extend between the top edge and the bottom edge. The impression tray also includes a base plate having a peripheral edge and a groove disposed in the base plate proximate a section of the peripheral edge. The groove is adapted to receive the bottom edge of segment of curable material, thereby supporting the segment of curable material as a vertical wall. The combination of the base plate and the vertical wall of curable material produces an impression tray. The impression tray is filled with impression material and placed in the mouth. As a patient bites into the impression material, the vertical wall curable material can be molded to the contours of the teeth and gums. Once cured, the impression tray and impression material create a highly accurate impression that can be used to better model prosthetics.
