Fuente: Wipo "digitalization" The invention relates to a computer-implemented method for providing a template for a casting matrix (101) configured for casting one or more artificial gingiva parts (142) of a removable denture. The casting matrix (101) comprises one or more recesses (117). Each of the recesses (117) has a 3D geometric form, which is a negative of a 3D geometric form of a section of the removable denture with one of the artificial gingiva parts (142) to be casted.
