1. A method for designing a denture, wherein the method comprises:
obtaining a digital 3D representation of the patient's soft tissue, said digital 3D representation comprising:
shape data expressing the shape of the soft tissue, and
texture data expressing a texture profile of the soft tissue; and
designing the denture such that a color of a soft tissue part of the denture is selected based on the texture profile of the corresponding part of the digital 3D representation,
wherein the step of obtaining the digital 3D representation is provided by recording a series of sub-scans that comprise the shape data and the texture data,
wherein the texture data at least partly is derived by combining texture information from corresponding parts of a number of the sub-scans.
