Abstract
A dental prosthesis is made by externally machining successive layers of wax, each of which is formed on a previous prosthesis layer and/or on a coping. Each wax layer is used to form a mold in situ over the previous prosthesis layer/coping, and the appropriate prosthesis material is cast or otherwise molded to conform to the wax layer by the mold.

-15. (canceled)
A method for producing a dental prosthesis on a dental coping, comprising:
- receiving a three-dimensional virtual model of the dental prosthesis;
- generating a plurality of virtual model layers based on a three-dimensional virtual model of the dental prosthesis forming a plurality of wax layers corresponding to the plurality of virtual model layers;
- and
- casting a plurality of prosthesis layers from the plurality of wax layers, wherein at least one wax layer of the plurality of wax layers is formed on a previously cast prosthesis layer in order to form at least one prosthesis layer of the plurality of prosthesis layers on the previously cast prosthesis layer.
1 more element
A system for producing a dental prosthesis on a dental coping, comprising:
- one or more processors comprising instructions that, when executed, cause the system to,
- receive a three-dimensional virtual model of the dental prosthesis
- generate a plurality of virtual model layers based on the three-dimensional virtual model of the dental prosthesis,
- produce the dental prosthesis on the coping based on the three-dimensional virtual model layers by forming a plurality of wax layers corresponding to the plurality of virtual model layers and casting a plurality of prosthesis layers from the plurality of wax layers, and
- form at least one wax layer of the plurality of wax layers on a previously cast prosthesis layer in order to cast at least one prosthesis layer of the plurality of prosthesis layers on the previously formed prosthesis layer.

A method for producing a dental prosthesis on a dental coping, comprising:
- providing the dental coping;
- forming a first wax layer on the dental coping based on a first virtual model layer of a three-dimensional virtual model of the dental prosthesis;
- casting a first prosthesis layer from the first wax layer such that the first prosthesis layer is cast on the dental coping;
- and
- forming a second wax layer on the first prosthesis layer based on a second virtual model layer of the three-dimensional virtual model of the dental prosthesis.
