Abstract
After the shape of the zone of implantation in the mouth is obtained by direct impression, micro-sensing or optical impression, a prosthesis or a mold for making a prosthesis is automatically machined by machine tool at a work center with the assistance of a calculator or computer which takes into consideration the shape obtained, the material or materials which are to be shaped, and other parameters such as thicknesses and the like which are essential to the proper shape and configuration of the prosthesis which is thus fabricated. The prosthesis can be a crown, bridge or part or assembly of both.
Claims17
In a process for producing a dental prosthesis for location at an implantation zone in a mouth of a subject, and in which the shape of the implantation zone is determined by talking an optical impression thereof, the improvement wherein the process comprises the steps of:
- fabricating a body with a shape corresponding to the determined shape of the implantation zone at a calculator-controlled work center utilizing a calculator from a blank whose shape and material are selected by said work center, by at least one machining operation determined by the calculator and carried out by a machine tool automatically controlled to effect said operation, said machine tool constituting said work center with said calculator;
- forming with said body a first part of the dental prosthesis;
- assembling a second part of said prosthesis on said first part after the machining and formation of said first part;
- and
- inserting said first part into the mouth of said subject at said zone.
