Method of manufacturing removable denture, removable denture, and removable denture manufacturing apparatus

A method of manufacturing a removable denture, comprising:

• producing three-dimensional removable denture data for a removable denture to be manufactured, by producing three-dimensional denture base data of a denture base, and three-dimensional artificial teeth data including artificial teeth arranged on the denture base, and an arrangement of the artificial teeth;
• building a bottomed frame body into which a base resin for forming the denture base, which is based on the denture base data, is filled, by using a rapid prototyping method;
• producing a resin block by casting the base resin into the frame body for covering base side portions of the artificial teeth that are opposite to occlusal surfaces of the artificial teeth for fully embedding the artificial teeth in the base resin, wherein the artificial teeth, which have been produced in advance, are arranged on a bottom portion of the built frame body based on the artificial teeth data;
• and
• milling the base resin of the resin block based on the removable denture data to create the denture base and manufacture the removable denture in which the base side portions of the artificial teeth are embedded in the denture base, by milling the frame body and the base resin of the resin block from both the bottom portion of the frame body and a side opposite to the bottom portion using a milling device, and by removing the base resin attached to surfaces of the artificial teeth other than the base side portions of the artificial teeth,
• wherein, in the milling, the removable denture in which the artificial teeth are arranged on the denture base according to the removable denture data is milled by milling surfaces of the artificial teeth based on the artificial teeth data in a case in which the arrangement of the artificial teeth embedded in the base resin does not match the artificial teeth data.
