Abstract
The invention discloses an all-porcelain tooth staining fluid with a color indication function and a preparation method thereof. The all-porcelain tooth staining fluid is prepared from raw materials such as deionized water, staining nitrate, a dispersing agent and a color indicator according to a ratio. Specifically, the method comprises the steps of: dissolving the staining nitrate and the dispersing agent into the deionized water so as to prepare the staining solution; dissolving the color indicator and the dispersing agent into the deionized water so as to prepare a color indicator solution; and mixing the two solutions according to a proper ratio so as to obtain the all-porcelain tooth staining fluid with the color indication function. The indicator is added into the staining fluid, so that the staining fluid shows different colors in a use process, and the all-porcelain tooth staining blindness and experimental performance are thoroughly avoided; the indicator completely exerts in a sintering process and does not influence the sintered porcelain body, so that the all-porcelain tooth quality is effectively improved.
Description
Technical field
The present invention relates to a kind of staining fluid and preparation method thereof for full porcelain tooth with color indication, belong to materials science field.
Background technology
Use the full porcelain dummy of dental CAD/CAM fabrication techniques, for the automatization processing of dummy and the making of high strength all-ceramic crown bridge open up a new way.Zirconium white is as topmost dental all-ceramics substrate crown material, and the ivory white that is white in color after its sintering, although have certain translucency, can not meet the clinical requirement to dummy color more.The actual demand of repairing in order to meet clinical artificial tooth, often to hide look to full porcelain substrate crown, make it lose partially transparent, the color of zirconium white itself is adjusted to consistent with the color of intending repairing tooth, lightness and saturation ratio, thereby obtain good texture, the reserves space that can save clinical abutment simultaneously.
For meeting the above-mentioned requirement that full porcelain substrate crown is hidden to look, mainly contain at present Zirconium powder painted and infiltration painted two kinds of technology.Zirconium powder is painted is in Zirconium powder, to add coloring oxide, prepares the Zirconium powder containing tinting material, and then forming and sintering obtains having the porcelain piece of different colours; This complete processing is complicated, and the corona color that sintering obtains is single, obtain the corona of different colours, must prepare different Zirconium powders, is unfavorable for large-scale batch production.And infiltration dye technology is mainly the staining fluid that contains metal ion by preparation, then staining fluid permeated or brush on pre-burning zirconium white, last sintering obtains the zirconium white corona with different colours; The method technique is simple, and the staining fluid that contains different metal ion or different ions concentration by preparation, or infiltration, brushes the different time and just can obtain required color.Therefore, permeating painted is the painted major technique of current Zirconium oxide full-porcelain.But because current all Zirconium oxide full-porcelains are on the market all colourless with the solution of staining fluid, in technical operation process, can not observe directly the painted depth and distribution, and must after completing, sintering could on full porcelain tooth, embody color, cause Color to be affected by human factors larger, in operating process, with certain blindness and empirical, the product factor of merit is lower.
In order to solve infiltration dye technology, be affected by human factors larger shortcoming, Wang Hongjuan etc. (Chinese patent CN102512256 method of utilizing film to dye to full zirconium tooth) be take polyethylene as main raw material, by multilayer extrusion explained hereafter, go out to have the PE film that autohension is stronger, then this film printed or print painted, and be wrapped in crown surfaces, finally by thermal treatment, make colored particles transfer to crown surfaces to be dyeed, realized the effect that tinting material can intuitively present before sintering.Yet, the method increased PE film preparation, print the techniques such as painted and thermal treatment, make whole technique become very complicated.Meanwhile, domestic and foreign literature retrieval shows, few for the research report of full porcelain tooth infiltration dye technology at present.
Summary of the invention
The present invention is directed to infiltration dye technology and be affected by human factors larger shortcoming, a kind of dental staining fluid with indication Color and preparation method thereof is proposed, solve blindness in full porcelain tooth permeating coloring process and empirical, improve the factor of merit of full porcelain tooth product.
The full porcelain tooth staining fluid with color indication that the present invention proposes, its raw-material mass fraction consists of:
Described dyeing can be one or more in iron nitrate, Erbium trinitrate, cerous nitrate, praseodymium nitrate and Bismuth trinitrate with nitrate; Described dispersion agent can be one or more in oleic acid, lipid acid, polyoxyethylene glycol PEG, PVAC polyvinylalcohol, polyvinyl butyral acetal PVB, poly amic acid PAA and BYK180; Described color indicator can be one or more in methyl violet, malachite green, Congo red, tetrabromo-mcresolsulfonphthalein sodium, tetrabromophenol sulfonphthalein sodium, tropeolin-D, Bromothymol blue sodium, p-dimethylamino-azo-benzene, methyl red, reindeer moss, toluylene red, indigo carmine and anthocyanidin.
The preparation that the present invention proposes has the method for staining fluid for the full porcelain tooth of color indication, comprises the steps:
(1) using 100 parts of deionized waters as solvent, add nitrate and 10～50 parts of dispersion agents for 1～25 part of dyeing, be uniformly mixed, obtain dyeing solution;
(2) using 100 parts of deionized waters as solvent, add 0.01～0.5 part of color indicator and 10～50 parts of dispersion agents, be uniformly mixed, obtain color indicator solution;
(3) in above-mentioned 100 parts of solution for dyeing (1), add 5～20 parts of color indicator solution (2), be uniformly mixed, obtain the full porcelain tooth staining fluid that the present invention has color indication.
Beneficial effect: the present invention compared with prior art, tool has the following advantages: (1) by adding a small amount of indicator solution in special dyeing liquid, realized staining fluid and can show different colours before sintering, and indicator can be in sintering process volatilization completely, on the porcelain body after sintering without any impact; (2) by this staining fluid brushing, spraying or infiltrate on zirconium white pre-burning porcelain body, can show the different colours such as red, yellow, blue, orange, purple, apple green, yellowish green and bluish-green, according to the depth of Show Color, can adjust the painted time, thereby stop blindness in full porcelain tooth permeating coloring process and empirical, improve the factor of merit of full porcelain tooth product; (3) staining fluid of the present invention is in full accord with the use of existing staining fluid in operation, and does not need to do the change on any Method and process; (4) raw material sources of the present invention are extensive, with low cost, and production technique is simple simultaneously, are applicable to industrial production.
