1. A computer-implemented method for adjusting a position of artificial teeth of a denture, the adjusting comprising:
providing a digital 3D model of the denture comprising at least a first denture part, the first denture part being configured for a first jaw of a patient, the first denture part comprising a first dental arch, the first dental arch comprising a first plurality of artificial teeth to be adjusted, the first plurality of artificial teeth being arranged in a first artificial gingiva;
defining a first deformable gingiva section of the first artificial gingiva with a first deformable geometrical form, the first deformable gingiva section being located between teeth of the first plurality of artificial teeth and a first fixed gingiva section of the first artificial gingiva with a first fixed geometrical form; and
moving the first dental arch as a whole relative to the first fixed gingiva section in order to adjust a position of the first dental arch with the teeth of the first plurality of artificial teeth maintaining fixed positions relative to each other, the first deformable geometrical form of the first deformable gingiva section being deformed due to the moving of the first dental arch, whereas the first fixed gingiva section maintains the first fixed geometrical form.
