Abstract: A method and apparatus for forming a dental prosthesis in situ for the reration of one or more missing, worn or broken teeth. The method includes forming an elastomeric mold half containing a corrected model of tooth areas to be restored, and forming a hard model of the tooth areas after they have been prepared for restoration. A pair of channels are placed through the elastomeric mold at spaced apart locations. The elastomeric mold and the hard model are secured together to form an assembly including a mold cavity therein. The assembly is placed in a vacuum chamber which can be pumped to produce a vacuum inside the chamber and inside the mold. One of the channels of the mold is connected to an overflow container within the vacuum chamber, and the other of the channels is connected to a source of liquid prosthesis forming material which is contained outside of the vacuum chamber.
