High temperature alloy powder 3D printing partial denture

Abstract

The invention discloses a high temperature alloy powder 3D printing partial denture, which comprises a substrate material layer and a facing material layer, wherein the substrate material layer comprises the following materials in parts by weight: 30-50 parts of zirconium oxide, 12-15 parts of aluminum oxide, 6-9 parts of titanium nitride and 1-5 parts of colorant. The high temperature alloy powder 3D printing partial denture disclosed by the invention comprises the substrate material layer and the facing material layer; the internal structure of the high temperature alloy powder 3D printing partial denture is improved microcosmically in the manner of optimizing chemical components of the substrate material layer and the facing material layer; the high temperature alloy powder 3D printingpartial denture has high strength, abrasive resistance, roasting stability and beautiful surface.

Description

technical field [0001] The invention relates to the technical field of dentures, in particular to a 3D printed partial denture with superalloy powder. Background technique [0002] Dentures have long been manufactured as partial and / or complete dentures, in which artificial teeth to replace natural teeth are embedded in a material that mimics the patient's gums. [0003] In order to alleviate the pain that may occur to the patient, efforts are made to optimize the position of the teeth according to occlusion. For this purpose, after modeling the patient's oral situation in the articulator and installing the male model, before building said teeth in wax, the translational and rotational positions of the teeth concerned are checked and improved if necessary, for example by occlusalizing the teeth Grinding the surface or cutting surface, the tooth surface produced in this way is not smooth enough, the strength is not high, the baking stability is poor, and the surface color is...
