Description
Technical field
The present invention relates to materials science field, a kind of dental zirconium oxide pottery dye with color instruction
Color liquid.
Background technology
Current dental CAD/CAM fabrication techniques All-ceramic restoration body technique is the most ripe, automatization can be fully achieved and add
Work and the making of high intensity all-ceramic crown bridge.Zirconium oxide is as topmost dental all-ceramics substrate crown material, after its feature is for sintering
The most white to ivory white, although to have certain translucence, but and the clinical requirement to dummy color cannot be met.In order to
Reach the color needs of clinic artificial tooth, often to carry out full porcelain substrate crown hiding color so that it is lose partially transparent property, by adjusting
Transparency, color and the saturation of whole zirconium oxide itself, so that consistent with intending reparation tooth.Artificial tooth after dyeing, obtain good
While good texture, it is also possible to save the reserves space of clinical abutment.
For meeting the above-mentioned requirement that full porcelain substrate crown carries out hiding color, currently mainly there is Zirconium powder coloring and be impregnated with
Two kinds of technology of color.Zirconium powder coloring is interpolation coloring oxide in Zirconium powder, prepares the oxidation containing coloring agent
Zirconium powder body, then reshaping sintering obtains the porcelain block with different colours；This processing technique is relative complex, and the tooth that sintering obtains
Hat color is single, the corona of different colours to be obtained, it is necessary to prepare the Zirconium powder of different colours, is unfavorable for large-scale batch
Amount produces.And permeate dye technology mainly by the preparation dyeing liquor containing metal ion, then by dyeing liquor infiltration or
Brushing is on pre-burning zirconium oxide, and finally sintering obtains the zirconium oxide corona with different colours；The method technique is simple, and passes through
Preparation is containing different metal ion or the dyeing liquor of different ions concentration, or infiltration, brushes the different time and be achieved with
Required color.Therefore, infiltration coloring is the major technique of current Zirconium oxide full-porcelain coloring.But owing to dyeing on the market at present
Liquid less stable, the more difficult control of time of penetration length, the degree of depth and uniformity, with certain blindness and experience in operating process
Property, the product factor of merit is relatively low.
It is affected by human factors bigger shortcoming, in Publication No. CN102512256A to solve infiltration dye technology
State's patent discloses a kind of method utilizing thin film to dye full zirconium tooth, with polyethylene as primary raw material, by multilayer extrusion work
Skill is produced has the PE thin film that autohension is stronger, then this thin film prints or prints coloring, and is wrapped in corona table
Face, makes colored particles transfer to crown surfaces to be dyed finally by heat treatment, it is achieved that coloring agent before sintering can intuitively in
Existing effect.But, this method increase the preparation of PE thin film, print the techniques such as coloring and heat treatment so that whole technique becomes
Considerably complicated.Meanwhile, domestic and foreign literature retrieval shows, the research report currently for full porcelain tooth infiltration dye technology is considerably less.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of dental zirconium oxide pottery with color instruction
Porcelain dyeing liquor.
