THREE-DIMENSIONAL PRINTING METHODS AND MATERIALS FOR MAKING DENTAL PRODUCTS

摘要

The invention relates to a method for making a three dimensional dental prosthesis containing multiple cross-sectional layers, comprising a. applying wax-like polymerizable material onto a support surface to form a multi-layered, uncured prosthesis, each layer of the prosthesis being formed by an ink-jet printer jetting the polymerizable material onto the support surface; or applying wax-like polymerizable material into a powder bed comprising particulate powder material to form a multi-layered, uncured prosthesis; each layer of the prosthesis being formed by an ink-jet printer jetting the polymerizable material into a layer of the particulate powder so that the particulate bonds in selected areas; b. placing the prosthesis in the mouth of a patient and shaping the prosthesis over a targeted area by applying sufficient pressure; c. removing the shaped prosthesis from the mouth; and d. irradiating the prosthesis with curing light so that the prosthesis fully cures and hardens.
