ABSTRACT:
An assembly for and a method of fabricating dental restorations. Dental impression material is disposed in a dental tray having a pair of spaced side walls, and an impression of teeth is taken. A die cavity is formed directly around the dental tray and a solidifiable plastic mass is injected into the die cavities, which mass solidifies to form dies. Vertical serrations, including alternating vertically tapered ridges and valleys, are formed on the bases of the dies during the solidification thereof, and these vertical serrations interfit with similar surfaces formed on a dental articulator to position the dies against displacement in a horizontal plane in the dental articulator, yet allowing ready removal thereof vertically when desired.
