Abstract
The invention discloses a method for preparing a series of matching color dental titanium porcelain powders, which comprises the steps of color masking porcelain powder color matching and body porcelain powder color matching, wherein in the color masking porcelain powder color matching, at least three kinds of commercial ceramic pigments, such as vanadium-zirconium yellow, zirconium-praseodymium yellow, iron-zirconium pink and nickel-chromium gray are added by adopting color masking porcelain powder as the quality base number; in the body porcelain powder color matching, at least two kinds of commercial ceramic pigments, such as vanadium-zirconium yellow, zirconium-praseodymium yellow, iron-zirconium pink, iron-chromium yellow and nickel-chromium gray are added by adopting body porcelain powder as the quality base number; the color masking porcelain powder and the body porcelain powder after the pigments are added are respectively ball-milled for 20-30 hours; and after being dried, the ball-milled color masking porcelain powder and the ball-milled body porcelain powder are respectively charged into bottles for porcelain-baking on the surface of a pure-titanium substrate. The color masking porcelain powder and the body porcelain powder are respectively modulated into coloring porcelain powders in 16 colors in four series of A, B, C and D according to the currently general vita porcelain color card standard, and the coloring porcelain powders can be respectively selected according to different colors of natural teeth, thereby achieving the vivid and attractive effect.
Description
Technical field
The present invention relates to the preparation method of biomaterial, be specifically related to a kind of preparation method of dental titanium porcelain powders of the series of matching color that is used to satisfy different patients, different colours demand.
Background technology
Pfm (porcelain-fused-metal, PFM) complete crown has been widely used in clinically, but billon substrate ceramic crown costs an arm and a leg, and is difficult to apply; Nichrome often has genotoxic potentials such as allergy, gingiva black line, bans use of in the world.Compare with it, the biocompatibility excellence of pure titanium, safe in utilization, and also cheap, research titanium ceramic crown is current pressing for, and has the project of bright prospects again.
Domestic literature [practical stomatology magazine, 1996,12 (4): 275-278.] has been developed the special-purpose porcelain powders of titanium material, but its porcelain powders of developing only contains screening color porcelain, two kinds of powder body of body porcelain.Foreign patent (US5176747, US5288232, JP10094550, US5314334) composition and the preparation method of titanium porcelain powders have been introduced, its porcelain powders sintering temperature of developing is lower than 800 ℃, thermal coefficient of expansion and titanio body coupling, but its porcelain powders of developing is the bique powder of single white equally.More than research does not all relate to the configuration of color.Application number is the manufacture method that 200410015585.0 Chinese patent has been introduced the leucite ceramic material that is applicable to noble metal and nichrome, and prepared porcelain powders has been carried out series of matching color.
Abroad constitute by bonding porcelain, screening color porcelain and body porcelain about the titanium porcelain powders that company produced at present, and considered the color of different patient's teeth, mainly represent as VITATITANKERAMIK (VITA company, Germany), TiBond (Dentsply company, the U.S.), Surper porcerain (NORITAKE company, Japan), but the not announcement of relevant production technology, and have the problem that collapses porcelain, light discolouration after the clinical use.
Summary of the invention
When the present invention installs titanium porcelain corona for satisfying different odontopathy patients,, provide a kind of preparation method of dental titanium porcelain powders of series of matching color to the different demands of color.This method hides color porcelain, body porcelain porcelain powder by the fusion preparation, adding different colorants respectively in hiding color porcelain, body porcelain porcelain powder matches colors, make the screening color porcelain pigment and the body porcelain pigment of A, B, 16 color codes of four series of C, D according to present general ceramic prosthesis colour atla standard, the patient can select for use according to the creamy white of self, makes the porcelain corona true to nature, attractive in appearance.
