A method for providing a custom dental prosthesis, and a custom dental prosthesis. The peculiarity of the invention consists in that it comprises a method for generating a virtual CAD model of a custom dental prosthesis (1), which in turn comprises the steps of (i) having a starting virtual CAD model of the dental prosthesis (1) in which at least one entry implant hole (5) is defined for an implant screw (6) for fixing the dental prosthesis (1) to a dental implant (4), where the implant hole (5) has a longitudinal extension along an implantation axis (50); (ii) sectioning the starting virtual CAD model of the dental prosthesis (1) by way of at least one cutting plane (10) that is transverse to the implantation axis (50) so as to subdivide the starting virtual CAD model of the dental prosthesis (1) into a first component, or prosthetic element (2), and into at least one second component, or connecting element (3), producing respectively a virtual CAD model of the prosthetic element (2) and a virtual CAD model of the at least one connecting element (3);(iii) defining, in the virtual CAD model of the prosthetic element (2), at least one entry hole (7) for a screw (8) for fixing the prosthetic element (2) to the at least one connecting element (3), where the at least one hole (7) has a longitudinal extension along a prosthetic axis (70); (iv) selecting in the virtual CAD model of the prosthetic element (2) an angle of inclination of the prosthetic axis (70) with respect to the implantation axis (50) such that the at least one hole (7) is arranged on the inner side (9) of the dental prosthesis (1). |
