Embodiment 1

[0062] Embodiment 1—making of cast porcelain tiles

[0063] A cylindrical stainless steel custom-made mold is used to press GC resin sheets with an inner diameter of 12mm, a thickness of 0.35mm and 0.60mm, and three kinds of transparent nuclear porcelain specimens of A3 color IPS e.maxPressHT, LT and MO are produced by the lost wax-die casting method. Use 240#-1200# water sandpaper to polish the nuclear porcelain pieces to 0.25mm and 0.50m respectively, with an error of ±0.02mm; after the finished nuclear porcelain surface is sandblasted, pile A3 color decorative porcelain IPS.e.max cream dentin, The decorative porcelain is sintered in three times, and the decorative porcelain layer is polished to 0.25mm or 0.50mm with 240#-1200# water sandpaper, and the error is ±0.05mm.

[0064] Finally, 4 pieces of each kind of transparent cast porcelain pieces are produced, and the thicknesses of decorative porcelain / core porcelain are 0.25mm / 0.25mm, 0.5mm / 0.25mm, 0.25mm / 0.5mm and 0.5mm / 0....

Embodiment 2

[0065] Embodiment 2—production of ceramic tiles

[0066] Use silicone rubber impression material to make an impression of a cylindrical stainless steel mold with a diameter of 12 mm, fill the model with Shofeng refractory material, and polish both ends of the model smooth with water sandpaper. The layered molding method is used to successively build up IPSd.SIGN A3 color low-temperature opaque porcelain powder and body porcelain powder on the refractory model. The thickness of the opaque porcelain is 0.10mm, and the error is ±0.05mm. The body porcelain is fired three times. After the production is completed, use 240#-1200# water sandpaper to polish the total thickness of the porcelain tile to 0.50mm and 0.75mm.

Embodiment 3

[0067] Embodiment 3--CAD-CAM tile making

[0068] Choose A3 color VitablocsMarkII LT porcelain blocks, use CEREC software to design and manufacture three CAD-CAM tiles with a diameter of 12mm and a thickness of 0.50mm, 0.75mm and 1.00mm.

Abstract

The invention belongs to the technical field of auxiliary equipment for stomatology, and discloses an aesthetic effect display swatch for porcelain veneer repaired discolored teeth with different technologies and a manufacturing method. By analyzing the effects of different manufacturing processes and different process parameters on the chromatographic properties and semi-permeability of porcelainveneer repaired discolored teeth, the special aesthetic effect display swatch for the porcelain veneer repaired discolored teeth is designed, the chromaticity information of the swatch can be enteredinto a computer, and the computer simulation of the aesthetic effect can be realized through programming. The swatch enables patients to clearly see the affected teeth under a certain degree of discoloration, different tooth grinding amounts require different porcelain materials and manufacturing processes, and differences in aesthetic effects after repair helps the patients to make reasonable choices and establish reasonable aesthetics expectation. The special display swatch for the porcelain veneer can not only improve the aesthetic effect prediction of the porcelain veneer restoration of deep-stained teeth by a doctor before an operation, facilitates the communication between the doctor and the patient before the aesthetic restoration, and helps improve the patient's satisfaction withthe restoration effect.

Description

technical field [0001] The invention belongs to the technical field of stomatological auxiliary equipment, and in particular relates to an aesthetic effect display color plate and a manufacturing method for restoring discolored teeth with porcelain veneers using different techniques. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Porcelain veneers, as a minimally invasive aesthetic restoration method, not only can better preserve tooth tissue, but also have excellent aesthetic properties, and have been widely used in the aesthetic restoration of discolored anterior teeth. The aesthetic effect of porcelain veneers to restore discolored teeth is not only related to the degree of discoloration of abutment teeth, but also the porcelain material, thickness and processing technology will affect the final restoration effect. At present, when porcelain veneers are used to restore discolored teeth such as te...
