<p>The invention concerns a method for producing a dental prosthesis consisting in the following steps: producing by casting an impression of the implantation zone of the human body; establishing, on the basis of the moulded impression, a digital three-dimensional representation (R1) of the implantation zone; defining a digital three-dimensional representation (R1c) of the internal surface of the prosthesis, defined on the basis of the digital three-dimensional representation (R1) of the implantation zone; defining a digital three-dimensional representation (R2) of the external surface of the prosthesis, defined on the basis of the surrounding parameters of the prosthesis and the digital three-dimensional representation (R1c); and defining a digital three-dimensional representation (R3) of the external surface of the cap, defined on the basis of the external (R2) and internal (R1c) surfaces of the prosthesis, taking into account the criteria of mechanical and aesthetic characteristics which the cap must have.</p> |
