Description
Technical Field
The invention relates to the technical field of denture processing, in particular to a denture dyeing and glazing patch and a preparation method and application thereof.
Background
With the improvement of the living standard of people, people have more and more abundant diet, and if the people do not pay attention to the oral hygiene, the health of teeth can be damaged. At present, once a problem occurs in a tooth or a dentition, a dentist can help a patient to fill the tooth, wear a false crown, and perform a dental implant or other cosmetic methods to restore the health of the tooth or the dentition. The tooth filling for the patient is that a dentist can directly fill the patient in an outpatient clinic, other forms of prosthetic teeth are needed, the dentist needs to be sent to a processing plant, and the dental prosthesis is designed and manufactured by a technician in the processing plant. In the existing prosthetic denture, the finished crowns, either porcelain crowns or full crowns, need to be finally stained on the surface of the teeth, because the teeth of each person can have differences in details, and the teeth are required to look vivid and need careful external staining treatment.
At present, the process of dyeing and glazing false teeth in a processing factory is as follows: firstly, referring to the color condition of the teeth of a patient for color matching. According to the color requirement written on the dental design sheet, a technician in a processing factory selects a toner with a similar color, the toner is uniformly mixed by using oil, then the mixed paste is coated on the surface of the false tooth by using a writing brush, the false tooth is dyed into the required color, and then the false tooth is placed in a porcelain oven for sintering, the toner is melted and softened during sintering, becomes a colored glass state and is attached to the surface of the false tooth, so that the surface of the false tooth presents the required color. The specific sintering curve is set according to the temperature required by different brands of toners; the second step is that: on the basis of the first step, the color of each different part of the false tooth is further optimized, for example, the neck of the false tooth is coated with a slightly darker color, the middle part of the false tooth has a normal transition color, so that the false tooth looks more natural, and the cut end of the false tooth is added with a little gray, blue or white color and the like, so that the cut end of the false tooth looks richer in color and more stereoscopic, and then the false tooth is placed in a porcelain oven for sintering, so that the toner is vitrified and attached to the surface of the false tooth; the third step: and (3) coating a layer of glaze on the surface of the dyed denture to ensure that the denture has enough brightness, and then sintering in a porcelain oven.
However, the traditional dyeing and glazing method in a processing factory completely depends on a technician holding a writing brush to slowly coat the pigment and the glaze on the false tooth as if the painting is performed, which has high requirements on the technician, not only requires the technician to accurately color, but also has certain aesthetic value, so that a processing factory needs to train a qualified technician to consume a large amount of time and economic cost. Moreover, the labor cost of dyeing and glazing treatment is long, the process is complicated, repeated brushing and sintering are needed, and the labor cost is higher and higher, so that the cost of manufacturing teeth in a processing factory is increased. Therefore, there is a need to develop a dyeing and glazing method that can meet the requirement of dyeing and glazing false teeth and can improve the efficiency and save manual operation.
