Technical Field

The invention belongs to the technical field of material science, and relates to a staining solution for zirconia pre-sintered false teeth and an application method thereof.

Background

The zirconium oxide material has wider application field along with the popularization of CAD/CAM technology, especially the zirconium oxide material is applied to the zirconium denture, the zirconium denture is directly formed integrally by CAD/CAM cutting without facing porcelain, and the hardness can completely meet the function of the oral cavity as long as the thickness of the material reaches the basic requirement. With the continuous pursuit of dental aesthetics, the color of dentures is one of the aesthetically important items. The zirconia material is divided into white zirconium and colored zirconium, the white zirconium is a colored porcelain block in the interval from white to ivory white, and the colored zirconium is colored by adopting a technology of directly adding coloring oxides into powder. In the process of processing the zirconium oxide material into the finished product of the full-zirconium denture, the special dyeing liquid is needed to be soaked and coated for simulating the color of natural teeth when the material is still a pre-sintered blank after being cut. Therefore, the dyeing liquid for the false teeth has the requirements of no toxicity, no harm, short dyeing penetration time, stable property and good dyeing effect.

The existing dyeing liquid for zirconia pre-sintered false teeth cannot achieve good permeation effect, shorten dyeing time and simultaneously do not influence the permeability and optical effect of materials because of the components and the proportion. Therefore, the research and invention of the dyeing liquid for the zirconia pre-sintered denture, which has short dyeing penetration time, low cost and good dyeing effect, has important significance for the aesthetic effect and the color simulation of the full-zirconium denture.

Disclosure of Invention

The invention aims to solve the technical problem of providing the dyeing liquid for the zirconia pre-sintered denture, which has good permeability, short dyeing permeation time, no toxicity and no harm, is matched with the application method to be applied to the zirconia pre-sintered denture dyeing, has good uniformity and glossiness, is close to the natural tooth color, has stable and durable dyeing effect, and does not influence the permeability and the optical effect of a zirconia material.

The technical scheme of the invention is as follows:

the staining solution for the zirconia pre-sintered denture comprises the following components in parts by weight: 1000 parts of deionized water, 6-85 parts of nitrate colorant, 40 parts of penetrant and 5 parts of indicator.

Further, the nitrate colorant is at least one of erbium nitrate and ferric nitrate.

Further, the ferric nitrate dyeing solution comprises 10-85 parts of erbium nitrate and 6-30 parts of ferric nitrate.

Further, the penetrating agent is polyethylene glycol.

Further, the indicator is carmine.

An application method of a staining solution for zirconia pre-sintered dentures comprises the following steps:

s1, adding a nitrate coloring agent, a penetrating agent and an indicator into deionized water serving as a solvent, and stirring until the nitrate coloring agent, the penetrating agent and the indicator are completely dissolved to obtain a staining solution for zirconia pre-sintered denture;

s2, soaking the cut zirconia pre-sintered denture in the staining solution for the zirconia pre-sintered denture, staining for 5-20s, baking for 20-25min by using an infrared lamp, and sintering for 8-9h at 1530-1550 ℃ to finish staining.

The invention has the following beneficial effects:

the nitrate coloring agent selected by the invention does not influence the permeability and the optical effect of the zirconia material, and the coloring is uniform and durable; the dyeing liquid can fully and quickly permeate into the zirconium oxide material by matching with the penetrant; the selected indicator does not affect the additional color development effect of the nitrate coloring agent and the glossiness of the surface of the zirconia material, and the dyeing time can be adjusted according to the shade of the color of the indicator, so that the controllability of the dyeing process is realized, the blindness of the dyeing process is avoided, and the stability and the success rate of the dyeing process are improved. The components are cooperated, so that the zirconium oxide pre-sintered coloring agent for the denture has good permeability, the dyeing penetration rate is improved, the 5s unidirectional penetration is 0.8mm, the 10s unidirectional penetration is 1.2mm, the 20s unidirectional penetration is 1.5mm, and the rapid and uniform dyeing liquid penetration speed in all directions is realized. The application method of the zirconium oxide pre-burning denture coloring agent is matched, the conditions such as dip-dyeing mode, time and the like are limited, the color obtained after the zirconium oxide pre-burning denture coloring is close to the natural tooth color, and the color is stable and durable. The zirconium oxide pre-sintering denture staining solution has the advantages of non-toxic and harmless formula, wide material source, low cost, simplicity and easiness in obtaining, simple and efficient application method and suitability for industrial production.
