Embodiment 1

[0045] A custom-made fixed denture processing method, comprising the following processing steps:

[0046] Step 1: Sterilize the parts, accept the original dental model from the dentist, conduct disinfection inspection on the dental model, and proceed to the next step after passing the inspection, and submit unqualified products to the dentist for re-modeling; the specific disinfection process can be applied to disinfection soaking method and ultraviolet irradiation method , Model disinfection and sterilization machine or the method of adding medicine in gypsum to eliminate bloodstains, saliva and bacteria etc. on gypsum, adopt disinfection soaking method in the present embodiment, specifically put the original denture into 0.5% 84 disinfectant and soak for 20min; The inspection is usually to check whether the incoming model is intact, whether the impression is clear, etc., put the inspected model in the qualified area, the area to be judged, the area to be inspected, and the un...

Embodiment 2

[0064] The difference between Example 2 and Example 1 lies in the different sintering parameters in step 7. Specifically, the sintering temperature of the first stage is 1100°C, the sintering time is 28min, the temperature of the second stage is 1550°C, and the sintering time is 1.5h .

Embodiment 3

[0066] The difference between Example 3 and Example 1 lies in the different sintering parameters in step 7. Specifically, the sintering temperature of the first stage is 1150° C., the sintering time is 30 minutes, and the temperature of the second stage is 1500° C., and the sintering time is 2 hours.

Abstract

The invention relates to a custom-made denture processing method in the field of denture processing, which aims to solve the problem that existing dentures tend to have ceramics during use. The technical solution includes joint disinfection-making plaster models-design-CNC cutting-plasma Body treatment-dyeing-sintering-turn gold-porcelain-car porcelain-polishing-sand blasting-cleaning-finished product post-processing. Under the action of the zirconia cutting in the plasma generator before dyeing, the plasma treatment can significantly increase the hydrophilicity of the zirconia surface without changing the shape of the zirconia surface, and increase the zirconia material and dyeing. The adhesiveness of the components can effectively improve the phenomenon of porcelain stretching during use of zirconia dentures, and the dentures have good stability.

Description

technical field [0001] The invention relates to the technical field of denture processing, in particular to a custom-made fixed denture processing method. Background technique [0002] At present, more and more patients and physicians choose all-ceramic materials as permanent dental restorations. All-ceramic materials have incomparable advantages over metals. It does not stain the gums, does not expose the metal base, does not cause corrosion in the mouth, and has excellent aesthetic effects. [0003] In clinical application, it is found that the color of zirconia ceramic restorations is worse than that of cast glass ceramics and infiltrated ceramics. The reason is that the color of the zirconia underlying crown is single, and there is only one chalky color. Compared with the base color system of other all-ceramic materials, Appears single. In-cream's alumina-based porcelain has 4 basic colors, and IPS-Empress heat-pressed cast ceramic bottom crowns also have 5 basic color...
