Modeling and manufacturing of dentures

A method for creating a digital model of a denture for a patient, where the denture comprises a gingival part and artificial teeth, and manufacturing a denture for a patient, the method comprises:

• 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 with the 3D scan and the digital artificial teeth;
• defining a first offset having 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;
• defining a second offset having 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;
• manufacturing the digital models of artificial teeth in a first material;
• manufacturing the gingival part in a second material;
• and
• manufacturing at least part of the denture by means of computer aided manufacturing (CAM).
