  • Method of making a prosthesis, especially a dental prosthesis
    Patent number: 4742464
    Abstract: A method of making a dental prosthesis in which data representing standard tooth shapes and sizes, relationships between teeth and adjacent and occlusive teeth and characteristics for securing a prosthesis to a prepared site, and machining instructions for shaping a blank to the configuration of a dental prosthesis for direct implantation are stored in a computer memory. After preparing a site in the mouth of a patient to receive a dental prosthesis, the dental surgeon projects optically a grating upon said site in the mouth of the patient and generates an interference pattern representing a holistic impression of said site and its relationship to adjacent structures. The interference pattern is converted into data along x,y,z coordinates in a cartesian coordinate system representing machining of a blank to fit said site and matching data obtained by comparing the impression with the computer standards are used to select a best-fit shape and size.
