Problems solved by technology

At present, the existing color charts are all based on the principle of porcelain teeth. The structure is the base layer and the finish layer. The color rendering effect is composed of the base layer color, the finish layer color, and the glaze. The principle of color formation is completely different from that of zirconia restorations. In the two processes of color transmission and reproduction, deviations are prone to occur, which leads to defects in the existing color guides in the color comparison of all-ceramic restorations, especially zirconia restorations.

Embodiment 1

[0022] A preparation method of a zirconia all-ceramic tooth colorimeter, comprising the following steps:

[0023] S1. Preparation of abutment: Use CAD / CAM technology to cut Japanese TOSOH zirconia block, cut out the abutment-shaped zirconia abutment material, use Edith HONOR ANTERIOR A1 color dyeing solution to dip-dye for 10 seconds, and then sinter after dip-dyeing. The temperature is 830°C, and the sintering time is 2 minutes, and the A1 color abutment is obtained;

[0024] S2. Prepare the crown: use CAD / CAM technology to cut the Japanese TOSOH zirconia block, cut out the crown-shaped zirconia crown material, and then carry out internal dyeing: first apply D-MAX ICE-BLUE incisal liquid on the zirconia The incisal end of the crown material, and then soak the zirconia crown material in Edith HONOR ANTERIOR A1 color staining solution for 10 seconds, take it out and dry it at 110°C for 30 minutes. After drying, crystallize, the crystallization temperature is 1450°C, and the cr...

[0027] A dyeing solution, with 1000 parts of deionized water as a solvent, adding 18 parts of erbium nitrate colorant, 8 parts of ferric nitrate colorant, 40 parts of polyethylene glycol, and 5 parts of carmine, and stirring until completely dissolved to obtain A1 color staining solution.

[0028] A preparation method of a zirconia all-ceramic tooth colorimeter, comprising the following steps:

[0029] S1. Preparation of abutment teeth: use CAD / CAM technology to cut zirconia blocks, cut out abutment-shaped zirconia abutment teeth materials, use A1 color dyeing solution for 20 seconds, and sinter after dipping. The sintering temperature is 830°C, and the sintering time is In 2 minutes, the A1 color abutment is obtained;

[0030] S2. Preparation of dental crown: use CAD / CAM technology to cut the zirconia block, cut out the crown-shaped zirconia crown material, and then carry out internal dyeing. The crown material was soaked in A1 color staining solution, dipped for 10s, dried...

Embodiment 3

[0033] A dyeing solution, using 1000 parts of deionized water as a solvent, adding 10 parts of erbium nitrate colorant, 20 parts of ferric nitrate colorant, 40 parts of polyethylene glycol, and 5 parts of carmine, and stirring until completely dissolved to obtain D4 color staining solution.

[0034] A preparation method of a zirconia all-ceramic tooth colorimeter, comprising the following steps:

[0035] S1. Preparation of abutment teeth: use CAD / CAM technology to cut zirconia blocks, and after cutting out abutment-shaped zirconia abutment teeth materials, use D4 color dyeing solution to dip for 20 seconds, and then sinter after dipping. The sintering temperature is 830°C, and the sintering time is In 2 minutes, the D4 color abutment is obtained;

[0036] S2. Preparation of dental crown: use CAD / CAM technology to cut the zirconia block, cut out the crown-shaped zirconia crown material, and then carry out internal dyeing. The crown material was soaked in D4 color staining sol...

Abstract

The invention relates to a preparation method of a colorimetric sheet for a zirconia all-ceramic tooth. The method comprises the following steps: cutting a zirconia block, cutting out an abutment tooth-shaped zirconia abutment tooth material and then performing dipping with a dyeing solution, and performing sintering to obtain an abutment tooth; cutting a zirconia block, cutting out a dental crown-shaped zirconia dental crown material and then performing internal dyeing and external dyeing on the zirconia dental crown material by using the dyeing solution and an end-cutting solution, and performing sintering, glazing, re-sintering, and polishing to obtain a dental crown; and bonding the inner surface of the dental crown to the abutment tooth with an adhesive to obtain the colorimetric sheet. The preparation method is basically unified with a material and a dyeing process of an all-zirconium prosthesis, the color, glossiness, and transparency of the colorimetric sheet prepared by the preparation method are closer to that of the all-zirconium prosthesis and a natural tooth, the color-developing effect is stable and lasting, the color has a strong three-dimensional sense, the colorimetric accuracy is high, and transmission and reproduction of the color can be more accurate.

Description

technical field [0001] The invention relates to a preparation method of a zirconia all-ceramic dental color comparison sheet. Background technique [0002] The shade guide plays the role of transmitting color in oral restoration. First, the doctor selects the shade guide with the closest color according to the shade guide, and then the technician who makes the restoration reproduces the color on the selected shade guide on the restoration. At present, the existing color charts are all based on the principle of porcelain teeth. The structure is the base layer and the finish layer. The color rendering effect is composed of the base layer color, the finish layer color, and the glaze. The principle of color formation is completely different from that of zirconia restorations. In the two processes of color transmission and reproduction, deviations are prone to occur, which leads to defects in the existing color guides in the color comparison of all-ceramic restorations, especiall...
