SYSTEM AND METHOD FOR MANUFACTURING A DENTAL PROSTHESIS AND A DENTAL PROSTHESIS MANUFACTURED THEREBY

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.
