Method and system for digital fabrication of denture

A method for digital fabrication of a denture, comprising:

• editing attributes of one or more three-dimensional models of a prefabricated tooth, and establishing a template database comprising the one or more three-dimensional models of the prefabricated tooth, wherein the attributes comprise a tooth position, a pose, and a feature marking point;
• obtaining oral data of a patient, and performing tooth arrangement design and base design, wherein the tooth arrangement design comprises selecting, from the template database or generating, according to a feature parameter of the patient, the one or more three-dimensional models of the prefabricated tooth, and the tooth arrangement design and the base design are used to generate a virtual denture model representing a form of the denture;
• determining, based on the virtual denture model, a three-dimensional model of a positioning auxiliary body for positioning a corresponding physical prefabricated tooth;
• fabricating a materialized positioning auxiliary body according to the three-dimensional model of the positioning auxiliary body;
• and
• using the materialized positioning auxiliary body to physically position and arrange the physical prefabricated tooth corresponding to the one or more three-dimensional models of the prefabricated tooth, and bonding the physical prefabricated tooth to a gingival base material, to form the denture.
