  • Digital integrated molding method for dental attachments
    Patent number: 11259904
    Abstract: A digital integrated molding method for dental attachments includes 3D design, aiming at acquiring 3D data of an attachment itself through 3D scanning of an attachment preform, carrying out modeling design directly on the basis of acquired data, adjusting corresponding positions of an inner-crown and an attachment, or a bridge and an attachment by design software, and directly designing the attachments of the inner-crown and the bridge into a whole; data processing, aiming at slicing the integrated inner-crown and attachment or bridge and attachment for additive manufacturing; and additive manufacturing, aiming at processing an integrated inner-crown, bridge or attachment. The molding method can greatly improve the molding accuracy of dental attachments, and ensure the relative accuracy of inner-crowns, bridges or attachments.
