The invention provides a full-process
digital manufacturing method of complete
dentures. The full-process
digital manufacturing method comprises the following steps: acquiring an
STL file of three-dimensional data by intraoral scanning of a patient with complete edentulous jaw; putting the median occlusal tray into the mouth, recording the morphology of the
mucous membrane surface of the upper jawand the lower jaw and the relative position relation of the upper jaw to the lower jaw, obtaining an
STL file of three-dimensional data of the median occlusal tray by scanning; and obtaining a DICOMfile about
spiral CT or CBCT of the edentulous jaw patient wearing the median occlusal tray. The full-process
digital manufacturing method of the present invention has the advantages as follows: 1, athree-dimensional space about maxillofacial region of the patient is constructed by fitting four digital files, and the
occlusal plane in which the patient tries on the
dentures and morphology and position of the
anterior teeth are set with reference of the anatomical structure of the maxillofacial region of the patient, thereby improving the try-on effect of the
dentures; 2, a final impression scanning and
copying technology is utilized to accurately manufacture the morphology of a final
denture base; and 3, a base plate and a artificial
dentition are obtained by adhering the separately
cut resin discs with different colors and high strength through
adhesive, thereby achieving high
cutting precision, high strength of the resin discs and good
wear resistance of the artificial teeth.
