[0033] Example: The production process of Satsukaze halo porcelain powder A1 color code (color comparison dental film component)
[0034] Materials and equipment: Nickel-chromium porcelain alloy (Shanghai Changping), Satsukaze Halo porcelain powder (Japan), Dentsply C-type porcelain furnace (Germany), prefabricated metal base wax model mold and facing porcelain layered mold .
[0035] Metal base part: several metal base wax models are pressed by the mold, embedded with "Beiyuan" brand porcelain tooth refractory embedding material produced in Luoyang, high-frequency precision casting, corrected grinding, sandblasting, ultrasonic cleaning, and then a porcelain furnace to heat up Pre-oxidize at 980°C for later use.
[0036] Porcelain part:
[0037] (1) Shading layer: Apply Satsukaze HaloA1 color paste covering porcelain on the metal base, bake it once according to the standard firing procedure of porcelain tooth covering porcelain given by the manufacturer, then recoat it again...

The invention provides a porcelain tooth shade guide and a production method of colorimetric dental films of the porcelain tooth shade guide and aims at enabling the colorimetric dental films of porcelain tooth shade guide to be identical to color and gloss of dermal teeth as far as possible. The porcelain tooth shade guide comprises a plurality of colorimetric dental film assemblies, and each colorimetric dental film assembly comprises a colorimetric dental film and a color scale handle. Each colorimetric dental film is formed by a metal base and multilayer veneering porcelain which is divided into a transparent porcelain layer, an incisal porcelain layer, a body porcelain layer and two layers of masking porcelain sequentially from the surface to the inside, and the metal base is fixedly connected with one end of the color scale handle through a screw. The colorimetric dental films of the porcelain tooth shade guide are nearly identical to clinical porcelain tooth prosthesis and dermal teeth in color and gloss, and therefore the porcelain tooth shade guide is reliable in accuracy when being used for guiding clinical color selection and color matching, is obviously prior to the traditional shade guide and can thoroughly solve the problem of inaccurate color matching which puzzles dentists for many years. Each batch of colorimetric dental films are all quantized, standardized and unitized in shape, size and thickness, and therefore the colorimetric dental films can be massively produced.
Description
technical field [0001] The invention relates to a porcelain tooth shade guide and a preparation method thereof. Background technique [0002] When a porcelain tooth is worn in the patient's mouth, in order to achieve the effect of being fake, in addition to the realistic shape, more importantly, the color and luster should be consistent with or close to the patient's real teeth when compared and observed under natural light. However, the traditional shade guide that instructs doctors to make porcelain tooth color selection and color matching has inevitable defects. For example, the color number of the porcelain tooth shade guide produced by each manufacturer does not match the corresponding color number of the porcelain tooth porcelain powder produced by itself, the porcelain layer is thick, and the incident light is almost completely absorbed. In a word, the visual consistency between the colorimetric tooth film on the traditional colorimetric board and clinical porcelain ...
