Removable denture processing technology

Abstract

The invention relates to the technical field of denture processing and discloses a removable denture processing technology. The processing technology comprises the steps as follows: S1, model production; S2, base plate production; S3, denture selection; S4, denture processing; S5, denture assembly. The S5 comprises steps as follows: a, applying ceramic resin for forming a white polymerization ceramic layer outside a germule, and then, performing light polymerization to form semi-finished denture; b, polishing the semi-finished denture into the size 85%-95% of the design standard; c, spraying powder for forming a transparent glaze layer on the semi-finished denture, then, performing microwave sintering polymerization to form a finished denture slightly larger than the design standard; d, polishing the finished denture into the size of design standard; in the step c, the powder contains gold nanoparticles with the particle size being 20-30 nm. Gold nanoparticles are mixed in the glaze layer, when visible light penetrates through the glaze layer, the gold nanoparticles absorb part of visible light, the thicker the glaze layer, the weaker the visible light reflected by the polymerization ceramic layer is, the color of the denture forms a white chromaticity system to facilitate selection, so that the personalized requirements of patients are met.

Description

technical field [0001] The invention relates to the technical field of denture processing, in particular to a movable denture processing technology. Background technique [0002] Dentures are what people often call "false teeth", just like "prosthetic legs" and "prosthetic limbs" are called "prosthetic limbs", "dentures" mean teeth that perform "duties" for human beings. In medicine, denture is a general term for restorations made after partial or complete tooth loss of upper and lower teeth. There are two types of dentures: removable and fixed. Fixed dentures cannot be taken and worn by patients themselves, while removable dentures can be taken and worn by patients conveniently. [0003] Removable dentures use the remaining natural teeth, the mucosa and bone tissue under the base as support, rely on the retainer of the denture and the base for retention, use artificial teeth to restore the shape and function of the missing tooth, and use the base material to restore the de...

Problems solved by technology

However, in terms of making personalized artificial teeth with removable dentures, hand-carving artificial teeth with wax blocks is still the most personalized operation method at present, and general technicians choose the corresponding shape and shape based on the wax embankment display and text prompts provided by the dentist. The commercially available artificial teeth of color and luster basically have no personalized tooth arrangement and modification, and are stereotyped, unable to meet the individual needs of patients
