As shown in fig. 1, the present embodiment provides a method for dyeing and glazing a denture using a printer and a membrane, the method for dyeing and glazing a denture using a printer and a membrane comprising:

s1: and printing a plurality of liquid pigments on the diaphragm by adopting a printer so as to form a pigment coating on the surface of the diaphragm, wherein the color of the pigment coating is the color difference between the color of the teeth in the oral cavity of the patient and the color of the denture to be colored.

The liquid color paints may include three primary colors of red, green and blue, or other colors according to actual needs. The material of the diaphragm can be one or a combination of more of plastic, cloth, ceramic and metal. The membrane is a plane sheet-shaped thin material; or the membrane is a three-dimensional sheet thin material and can be attached to the outer surface of the false tooth to be colored. The printer may be an ink jet printer, a UV printer, a ceramic printer or a laser printer. The liquid pigment is prepared by dissolving or/and suspending a solid pigment in a solvent. The solid colorant is preferably an inorganic colorant or an organic colorant which is currently used in the oral cavity. The solvent may be one of an aqueous solution, an acidic solution and an alkaline solution, and the solvent is selected according to the dissolution characteristics of the solid colorant. Taking inorganic pigment as an example, solid high-temperature resistant raw materials can be used, which are first prepared into solid compounds capable of being dissolved or suspended in a solvent through chemical and physical reactions, and then the solid compounds can be dissolved or suspended in the solvent to prepare liquid pigment. For example, iron oxide is a common inorganic pigment, the iron oxide pigment material is insoluble in water, the color development component of the iron oxide pigment material is iron ions, solid high-temperature-resistant iron oxide and a nitric acid solution are firstly reacted to prepare an iron nitrate solution, solid iron nitrate is further obtained through a physical reaction, and then the solid iron nitrate is dissolved in water to prepare the iron nitrate liquid pigment.

Optionally, in S1, the surface of the film may be coated with a transparent glaze, and the printer prints a plurality of liquid pigments on the transparent glaze according to a color ratio corresponding to the color difference data to form a pigment coating on the transparent glaze.

S2: and coating the pigment coating and the transparent glaze on the film on the denture to be colored in sequence to obtain the colored denture.

It will be appreciated that by applying the colorant coating to the denture to be colored according to the color difference between the color of the teeth in the patient's mouth and the color of the denture to be colored, the resulting colored denture will have a color that is consistent with the color of the teeth in the patient's mouth. The artificial tooth coloring device can adopt sponge or a hairbrush to dip the pigment coating and coat the pigment coating on the artificial tooth to be colored, also can dip the pigment coating and coat the pigment coating on the artificial tooth to be colored through a hand or a mechanical arm, and of course, can also adopt the combination of various modes in the sponge, the hairbrush, the hand and the mechanical arm.

S3: and (4) placing the colored false tooth in an oven for sintering to obtain the finished false tooth.

After sintering, the pigment coating and the clear glaze will set on the denture surface, and the clear glaze will form a protective layer on the denture surface. It is to be noted that if the solid coloring material is an organic coloring material, this step is not required.

According to the method for dyeing and glazing the false tooth by using the printer and the diaphragm, the liquid coating can be directly printed on the diaphragm through the printer according to the color difference between the color of the tooth in the oral cavity of the patient and the color of the false tooth to be colored, and the liquid coating and the transparent glaze are sequentially coated on the surface of the false tooth and then sintered, so that manual color mixing is avoided, and the false tooth coloring efficiency can be effectively improved. Moreover, the traditional manual color matching has higher requirements on the skill level of a technician, which also results in higher use cost of the technician, and the method for dyeing and glazing the false tooth by using the printer and the membrane provided by the embodiment can also effectively reduce the skill requirements on the technician.

Specifically, as shown in fig. 2, in S1, the method for printing a plurality of liquid pigments on a film by using a printer includes:

s10: a picture of healthy teeth in the mouth of a patient is taken.

Can be obtained by taking a picture of healthy teeth in the mouth of the patient. Healthy teeth are teeth that are not diseased in the mouth of the patient.

S20: the photograph is processed using a computer-assisted software program to obtain a first color of the tooth.

Computer-assisted software programs are known in the art and will not be described in detail herein.

S30: and obtaining a second color of the denture to be colored.

The method comprises the steps of obtaining a second color of the denture to be colored, obtaining a photo of the denture to be colored in a mode of photographing the denture to be colored, processing the photo of the denture to be colored by adopting a computer-aided software program to obtain the second color of the denture to be colored, directly obtaining the second color in a specification for manufacturing materials of the denture to be colored, and inputting the second color into the computer-aided software program.

S40: the color difference data between the first color and the second color is analyzed using a computer-assisted software program.

And the computer-aided software program analyzes the data of the color difference between the first color and the second color and stores the data into a format which can be printed by the printer.

S50: the printer prints a plurality of liquid pigments on the membrane according to the color proportion corresponding to the color difference data so as to form a pigment coating on the surface of the membrane.

The embodiment also provides a denture which is manufactured by adopting the method for dyeing and glazing the denture by using the printer and the membrane in the scheme. The false tooth can break through the limitation of region when being processed, and the operator can operate the computer-aided software program to control the printer in different places, thus the false tooth dyeing can be carried out in different regions.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
