Claim Text:
1. A method of making a dental prosthesis, the method comprising a) forming a first cavity in a first surface of a block of solid material, the first cavity having a bottom surface comprising a protrusion extending upwardly and shaped to correspond to an occlusal surface of the dental prosthesis; b) filling the first cavity with a green ceramic material; c) removing a first portion of the green ceramic material from the first cavity such that a remaining portion forms a layer of green ceramic material contiguous with the protrusion of the bottom surface of the first cavity and having a contour that corresponds to the shape of the protrusion; d) forming a second cavity in a second surface of the block of solid material, the second surface opposed to the first surface, the second cavity having an inner surface shaped to correspond to the surface of a tooth that is to receive the dental prosthesis and that corresponds to the protrusion of the bottom surface of the first cavity, thereby forming a coping made of the solid material and contiguous with the layer of green ceramic material and including the inner surface shaped to correspond to the surface of a tooth that is to receive the dental prosthesis; and e) sintering the coping and layer of green ceramic material to form the dental prosthesis.
