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 full porcelain tooth with color indication with staining fluid and preparation method thereof, 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 the full porcelain substrate crown of topmost dentistry material, and the ivory white that is white in color behind its sintering though have certain translucency, can not satisfy clinical requirement to the dummy color more.In order to satisfy the actual demand that clinical artificial tooth is repaired, often to hide look to full porcelain substrate crown, make its forfeiture 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.
Above-mentioned full porcelain substrate crown is hidden the requirement of look for satisfying, mainly contain the painted and painted two kinds of technology of infiltration of Zirconium powder at present.Zirconium powder is painted to be to add coloring oxide in Zirconium powder, prepares the Zirconium powder that contains tinting material, and then forming and sintering obtains having the porcelain piece of different colours; This complete processing complexity, 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 process.And the infiltration dye technology mainly is the staining fluid that contains metal ion by preparation, then with staining fluid infiltration or brushing on the pre-burning zirconium white, last sintering obtains to have the zirconium white corona of different colours; This method technology is simple, and contains the staining fluid of different metal ion or different ions concentration by preparation, or infiltration, different time of brushing just can obtain required color.Therefore, infiltration is painted is the painted major technique of present Zirconium oxide full-porcelain.But since at present on the market all Zirconium oxide full-porcelains all be colourless with the solution of staining fluid, in the technical operation process, can not observe directly the painted depth and distribution, and must after finishing, sintering could embody color at full porcelain tooth, it is bigger to cause Color influenced by human factor, have certain blindness and empirical in the operating process, the product factor of merit is lower.
Be subjected to human factor to influence bigger shortcoming in order to solve the infiltration dye technology, Wang Hongjuan etc. (Chinese patent CN102512256 utilizes film to the method for full zirconium tooth dyeing for one kind) are main raw material with the polyethylene, produce by the multilayer expressing technique and to have the stronger PE film of autohension, then this film is printed or print painted, and be wrapped in crown surfaces, make colored particles transfer to crown surfaces to be dyeed by thermal treatment at last, realized the effect that tinting material can intuitively present before sintering.Yet, this method increased the PE film preparation, print painted and technologies such as thermal treatment, make whole technology become very complicated.Simultaneously, the domestic and foreign literature retrieval shows, and is few at the research report of full porcelain tooth infiltration dye technology at present.
Summary of the invention
The present invention is directed to the infiltration dye technology is subjected to human factor to influence bigger shortcoming, a kind of dental staining fluid with indication Color and preparation method thereof is proposed, solve blindness in the 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 in iron nitrate, Erbium trinitrate, cerous nitrate, praseodymium nitrate and the Bismuth trinitrate one or more with nitrate; Described dispersion agent can be one or more among oleic acid, lipid acid, polyoxyethylene glycol PEG, PVAC polyvinylalcohol, polyvinyl butyral acetal PVB, poly amic acid PAA and the 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 the anthocyanidin.
The preparation that the present invention proposes has the full porcelain tooth of color indication with the method for staining fluid, comprises the steps:
(1) with 100 parts of deionized waters as solvent, add 1～25 part of dyeing with nitrate and 10～50 parts of dispersion agents, mix, obtain dyeing solution;
(2) with 100 parts of deionized waters as solvent, add 0.01～0.5 part of color indicator and 10～50 parts of dispersion agents, mix, obtain color indicator solution;
(3) at above-mentioned 100 parts of dyeing adding 5～20 parts of color indicator solution (2) in the solution (1), mix, namely obtain the full porcelain tooth staining fluid that the present invention has the color indication.
Beneficial effect: the present invention compared with prior art, have following advantage: (1) is by adding a small amount of indicator solution in special dyeing liquid, realized that staining fluid can show different colours before sintering, and indicator can be in sintering process volatilization fully, to the porcelain body behind the sintering without any influence; (2) with this staining fluid brushing, spraying or soak on zirconium white pre-burning porcelain body, can show different colours such as red, yellow, blue, orange, purple, apple green, yellowish green and bluish-green, the depth according to Show Color can be adjusted the painted time, thereby stop blindness in the 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 on use technology, and need not do any method and technologic change; (4) raw material sources of the present invention are extensive, with low cost, and production technique is simple simultaneously, are fit to industrial production.
