Problems solved by technology

[0002] Due to factors such as congenital factors, acquired living habits and accidents, many people currently need medical treatment for orthodontics and denture installation. Therefore, the current demand for dentures is huge. Factors and users’ specific color requirements for dentures require dentures to have a variety of different color features and good structural strength. It is carried out through the intermediate soaking dyeing and then sintering molding process. Although this production process can meet the needs of actual use, the color fastness of the denture is relatively poor, and it is easy to fade and secondary staining during use, and it also causes dentures. The structural strength and surface quality of dentures are relatively poor, which affects the performance and aesthetics of dentures. Therefore, in response to this problem, it is urgent to develop a new denture dyeing method to meet the needs of actual use.

Embodiment 1

[0017] Such as figure 1 Shown, a kind of denture dyeing process comprises the steps:

[0018] The first step is dip dyeing. Soak the denture base in the dyeing solution, let it sit for 10 seconds, take it out of the dyeing solution and use the liquid absorbent material to absorb and wipe off the excess dyeing solution on the surface of the denture base. The temperature of the dyeing solution is 30°C ;

[0019] The second step is drying. The denture base treated in the first step is forced to ventilate and dry, where the air velocity is 5m / s and the air temperature is -10°C;

[0020] The third step, color complementing, checks the color of the denture base after drying, and performs color complementing treatment with a porcelain pen on the position where there is color difference after drying, and then returns to the second step for drying until the color of the denture base is unified;

[0021] The fourth step is glazing. The outer surface of the denture base treated in the ...

Embodiment 2

[0025] A denture dyeing process, comprising the steps of:

[0026] The first step is dip dyeing. Soak the denture base in the dyeing solution, let it sit for 25 seconds, take it out of the dyeing solution and use the liquid absorbent material to absorb and wipe off the excess dyeing solution on the surface of the denture base. The temperature of the dyeing solution is 50°C ;

[0027] The second step is drying. The denture base treated in the first step is forced to ventilate and dry, where the air velocity is 8m / s and the air temperature is 50°C;

[0028] The third step, color complementing, checks the color of the denture base after drying, and performs color complementing treatment with a porcelain pen on the position where there is color difference after drying, and then returns to the second step for drying until the color of the denture base is unified;

[0029] The fourth step is glazing. The outer surface of the denture base treated in the third step is glazed, and the...

Abstract

The invention discloses a denture dyeing process which includes dip-dyeing, drying, color-supplementing, glazing, sintering and vapor-depositing. The denture dyeing process is simple, convenient and reliable, high in operation automation, capable of flexibly adjusting color of dentures and meeting different using needs on the dentures, capable of effectively improving surface quality and structural strength of the dentures and conducive to prolonging service life of the dentures.

Description

technical field [0001] The invention relates to a denture dyeing process, which belongs to the technical field of artificial dentures. Background technique [0002] Due to factors such as congenital factors, acquired living habits and accidents, many people currently need medical treatment for orthodontics and denture installation. Therefore, the current demand for dentures is huge. Factors and users’ specific color requirements for dentures require dentures to have a variety of different color features and good structural strength. It is carried out through the intermediate soaking dyeing and then sintering molding process. Although this production process can meet the needs of actual use, the color fastness of the denture is relatively poor, and it is easy to fade and secondary staining during use, and it also causes dentures. The structural strength and surface quality of dentures are relatively poor, which affects the performance and aesthetics of dentures. Therefore, i...
