ABSTRACT:
A method and apparatus for facilitating the formation of dental castings utilizing a dental impression tray. A collar assembly is provided which is substantially oval and forms an upstanding peripheral enclosure around the dental impression tray. A rod transversely spans across the oval member and is retained in notches at the upper edge of the oval member. The rods pass through spherical coupling members from which depend dowel pins which can enter into the negative impression and are used for retaining the teeth which are subsequently formed by a casting process.
