Abstract
The invention relates to the technical field of false teeth, in particular to a 3D printing false tooth material .The 3D printing false tooth material comprises zirconia enhanced lithium silicate glass ceramic used as a substrate material, the zirconia enhanced lithium silicate glass ceramic is matched with a facing material for carrying out personalized decoration on the zirconia enhanced lithium silicate glass ceramic .The facing material is the low-melting-point fine particle feldspar material .By means of perfect matching of coefficients of thermal expansion of the substrate material and the facing material, good bonding of the two materials and long-term stability of the facing material are ensured; the low-melting-point fine particle feldspar material is uniform, compact in surface and good in roasting stability and has excellent grinding and polishing performance, and therefore the surfaces of false teeth can be smooth and compact; the low-melting-point fine particle feldspar material has the high permeability and warn tone, meanwhile, the zirconia enhanced lithium silicate glass ceramic has an opalescence effect, and therefore the surface color can be fresh and attractive .
Description
Technical field
The present invention relates to artificial tooth technical field, particularly relate to a kind of 3D and print artificial tooth material.
Background technology
For a long time, manufacture artificial tooth as partial denture and/or complete denture, in the material imitating patient's gingiva, i.e. embed the artificial tooth of natural teeth to be substituted.
In order at least alleviate the contingent misery of patient, it is devoted to close according to tooth and optimization is made in the position of tooth.For this, after the oral conditions of patient is modeled and installs formpiston by articulator, before building described tooth with wax, check the translation position of associated teeth and position of rotation and improve when needed, the such as grinding of the occlusal surface or facet by carrying out tooth, the surface of denture so produced is the most smooth, roasting less stable, and surface color is the most attractive in appearance.
Therefore prior art still has bigger room for improvement.
Summary of the invention
It is an object of the invention to provide a kind of 3D and print artificial tooth material, it has and finishing material perfect adaptation, can make the smooth densification of surface of denture, roasting good stability, the feature that surface color is attractive in appearance.
For achieving the above object, the present invention uses following technical proposals:
