Method for fabricating a dental prosthesis part, comprising: - Provision of a data set of a dental prosthesis part for use in a CAD/CAM process, - Provision of reference data of the optical properties of various dentine materials and translucent enamel materials of the dental prosthesis part and of a relationship between these optical properties, the desired optical properties of the dental prosthesis part and the dimensions of the dental prosthesis part, - Selection of the desired color in which the dental prosthesis part is to be fabricated, - Determination of a first set value (S 1) of the optical properties of a dentine area of the dental prosthesis part, - Determination of a second set value (S 2) of the optical properties of an enamel area of the dental prosthesis part, - Determination of a third set value (S 3) of a thickness of the enamel area of the dental prosthesis part, - Selection and provision of a dental prosthesis block, which i) has a dentine area, which consists of a material whose optical properties correspond to the first set value (S 1) and ii) has an enamel area, which consists of a translucent material whose optical properties correspond to the second set value (S 2) and within which the dentine area is embedded forming a boundary surface, whereby the boundary surface has a first dentine surface and a second dentine surface, - Selection of a dentine surface (531, 532) depending on the desired shape and color of the dental prosthesis part, and - Fabrication of a dental prosthesis part by the CAD/CAM process by removal of material from the dental prosthesis block, whereby the thickness of the translucent material parallel to the selected dentine surface (531, 532) is reduced to the third set value (S 3). - Provision of a data set of a dental prosthesis part for use in a CAD/CAM process, - Provision of reference data of the optical properties of various dentine materials and translucent enamel materials of the dental prosthesis part and of a relationship between these optical properties, the desired optical properties of the dental prosthesis part and the dimensions of the dental prosthesis part, - Selection of the desired color in which the dental prosthesis part is to be fabricated, - Determination of a first set value (S 1) of the optical properties of a dentine area of the dental prosthesis part, - Determination of a second set value (S 2) of the optical properties of an enamel area of the dental prosthesis part, - Determination of a third set value (S 3) of a thickness of the enamel area of the dental prosthesis part, - Selection and provision of a dental prosthesis block, which i) has a dentine area, which consists of a material whose optical properties correspond to the first set value (S 1) and ii) has an enamel area, which consists of a translucent material whose optical properties correspond to the second set value (S 2) and within which the dentine area is embedded forming a boundary surface, whereby the boundary surface has a first dentine surface and a second dentine surface, - Selection of a dentine surface (531, 532) depending on the desired shape and color of the dental prosthesis part, and - Fabrication of a dental prosthesis part by the CAD/CAM process by removal of material from the dental prosthesis block, whereby the thickness of the translucent material parallel to the selected dentine surface (531, 532) is reduced to the third set value (S 3). i) has a dentine area, which consists of a material whose optical properties correspond to the first set value (S 1) and ii) has an enamel area, which consists of a translucent material whose optical properties correspond to the second set value (S 2) and within which the dentine area is embedded forming a boundary surface, - Selection of a dentine surface (531, 532) depending on the desired shape and color of the dental prosthesis part, and - Fabrication of a dental prosthesis part by the CAD/CAM process by removal of material from the dental prosthesis block, whereby the thickness of the translucent material parallel to the selected dentine surface (531, 532) is reduced to the third set value (S 3).
