A method for creating a digital model of a denture for a patient, where the denture includes a gingival part and artificial teeth, includes obtaining digital models of artificial teeth representing the artificial teeth； obtaining a 3D scan comprising a digital representation of at least part of the patient's existing gingiva； digitally modeling a gingival part of the digital model of the denture using the 3D scan and the digital artificial teeth； digitally determining a first offset defining a first thickness of a first portion of the gingival part of the digital model of the denture that extends from the digital representation of the at least part of the patient's existing gingiva； and digitally determining a second offset defining a second thickness of a second portion of the gingival part of the digital model of the denture that extends from the digital artificial teeth.
