Abstract
A method for producing a dental prosthesis includes computer modeling of a three-dimensional prosthetic cap based on an human implantation zone. The method first includes casting an impression of the implantation zone of the human body. Then, on the basis of the moulded impression, a digital three-dimensional representation (R ) of the implantation zone is made by sensing the implantation zone with a sensor. From this, a digital representation (R ) of the internal surface of the prosthesis is defined on the basis of the digital three-dimensional representation (R ) of the implantation zone. A digital three-dimensional representation (R ) of the external surface of the prosthesis is then defined on the basis of the surrounding parameters of the prosthesis and the digital three-dimensional representation (R ). Then, a digital three-dimensional representation (R ) of the external surface of the cap is defined on the basis of the external (R ) and internal (R ) surfaces of the prosthesis, taking into account the criteria of the mechanical and aesthetic characteristics which the cap must have. Based on this three-dimensional model, an actual prosthetic cap can be produced if the cap meets certain requirements.
