Abstract

The invention discloses a 3D printed zirconium oxide-based false tooth material and a preparation method thereof, and relates to the technical field of medical apparatus and instruments. The 3D printed zirconium oxide-based false tooth material comprises the following components in parts by mass: 50-65 parts of zirconium oxide ceramic powder, 0.8-1.6 parts of a dispersing agent, 4-7 parts of a binding agent, 0.7-2.6 parts of a reinforcing agent, 0.6-1.4 parts of a coloring agent, 20-30 parts of deionized water, 2-4 parts of a first stabilizing agent and 3-6 parts of a second stabilizing agent.The invention further discloses a preparation method of the 3D printed zirconium oxide-based false tooth material. The preparation method comprises the following steps: step A, base material preparing; step B, first material mixing; step C, second material mixing; step D, uniform dispersing; e, stable coloring; and step F, modulation. According to the 3D printed zirconium oxide-based false toothmaterial and the preparation method thereof, zirconium oxide is used as a base material, so that the false tooth material is higher in hardness and stronger in wear resistance; and through a 3D printing production mode, the false tooth material is effectively and quickly processed and formed, shorter in processing period, stable in quality and higher in popularization and use benefits.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a 3D printed zirconia-based denture material and a preparation method thereof. Background technique [0002] Denture is an important method applied to the restoration of tooth defects. Metal is the common denture material at present. The main materials are nickel-chromium alloy, titanium alloy, diamond-chrome alloy, etc. The existing denture processing methods are cumbersome, the production cycle is long, and the production The quality of the produced dentures is not stable enough, the degree of wear resistance is not high during use, and the dentures are prone to deformation or cracks during the use of the user, and the overall stability is not high. In addition, in the daily use of the user, the gloss of the denture is not easy to maintain , poor oxidation resistance, short service life. [0003] In China's invention patent application number: CN201610979137.5, a 3D pr...
