Dental Framework and Prosthesis

Abstract

A dental prosthesis and a process for design and manufacturing, incorporating a dental implant framework and veneering overlay that will be designed and manufactured simultaneously and permanently fixated to one another.

What is claimed: 
     
         1 . A unique subtract body intended to create the mating surface for a veneering overlay and a dental implant framework comprising:
 dimensions dependent upon the design features of the dental implant framework;   where some dimensions of the unique CAD subtract body are used in creating the mating surface for the veneering overlay to mate with the dental implant framework;   where some dimensions of the unique CAD subtract body are used in creating clearance gaps between the veneering overlay and dental implant framework;   where the unique CAD subtract body is parametric; and   where the design of the veneering overlay and dental implant framework is determined from digital data defining the appropriate tooth contours, gingiva contours and implant locations for the dental prosthesis.   
     
     
         2 . The unique CAD subtract body of  claim 1 , where in the digital data for the design of the veneering overlay and dental implant framework have been derived from one of the following scanning a diagnostic wax up or denture tooth set up; CAD models in a virtual set up; an intraoral scan of a diagnostic wax up or denture tooth set up taken in the patient's mouth; a CT scan or series of CT scans of the patient's mouth; a CT scan or series of CT scans with the use of a radiographic stent in the patient's mouth. 
     
     
         3 . The unique CAD subtract body of  claim 1 , where the veneering overlay is intended to intimately mate to at least one surface of the framework. 
     
     
         4 . The unique CAD subtract body of  claim 1 , where the veneering overlay and dental implant framework can be manufactured simultaneously.
