A method for generating a virtual CAD model of a custom dental prosthesis, comprising the steps of: i. having a starting virtual CAD model of said dental prosthesis in which at least one entry implant hole is defined for an implant screw for fixing said dental prosthesis to a dental implant, said implant hole having a longitudinal extension along an implantation axis; characterized in that if further comprises the steps of: ii. sectioning said starting virtual CAD model of said dental prosthesis by way of at least one cutting plane that is transverse, but not necessarily perpendicular, to said implantation axis so as to subdivide said starting virtual CAD model of said dental prosthesis into a prosthetic element, and into at least one connecting element, producing respectively a virtual CAD model of said prosthetic element and a virtual CAD model of said at least one connecting element; said cutting plane cutting said virtual CAD model of said dental prosthesis so as to define a prosthetic element with a cosmetic veneer and a connecting element with a cosmetic veneer, said cosmetic veneers (22, 32) defining a continuous profile; iii. defining, in said virtual CAD model of said prosthetic element, at least one further entry hole for a further screw for fixing said prosthetic element to said at least one connecting element, said at least one further hole having a longitudinal extension along a prosthetic axis; iv. selecting in said virtual CAD model of said prosthetic element an angle of inclination of said prosthetic axis with respect to said implantation axis such that said at least one further hole is arranged on the inner side of said dental prosthesis; said at least one further hole being accessible from the outside of said prosthetic component. i. having a starting virtual CAD model of said dental prosthesis in which at least one entry implant hole is defined for an implant screw for fixing said dental prosthesis to a dental implant, said implant hole having a longitudinal extension along an implantation axis; ii. sectioning said starting virtual CAD model of said dental prosthesis by way of at least one cutting plane that is transverse, but not necessarily perpendicular, to said implantation axis so as to subdivide said starting virtual CAD model of said dental prosthesis into a prosthetic element, and into at least one connecting element, producing respectively a virtual CAD model of said prosthetic element and a virtual CAD model of said at least one connecting element; said cutting plane cutting said virtual CAD model of said dental prosthesis so as to define a prosthetic element with a cosmetic veneer and a connecting element with a cosmetic veneer, said cosmetic veneers (22, 32) defining a continuous profile; iii. defining, in said virtual CAD model of said prosthetic element, at least one further entry hole for a further screw for fixing said prosthetic element to said at least one connecting element, said at least one further hole having a longitudinal extension along a prosthetic axis; iv. selecting in said virtual CAD model of said prosthetic element an angle of inclination of said prosthetic axis with respect to said implantation axis such that said at least one further hole is arranged on the inner side of said dental prosthesis; said at least one further hole being accessible from the outside of said prosthetic component.
