THREE-DIMENSIONAL PRINTING METHODS AND MATERIALS FOR MAKING DENTAL PRODUCTS

摘要

This invention relates to ink-jet printing systems for making dental products such as artificial teeth, dentures, splints, veneers, inlays, onlays, copings, frame patterns, crowns and bridges and the like. An ink-jet printer is used to discharge wax-like polymerizable material in a layer-by-layer manner to build-up the object. In other methods, a heated capillary or dropper can be used to apply the polymerizable material. The resulting three-dimensional object has good dimensional stability. Light irradiation can be used to cure and harden the material, thereby producing the final dental product.
