A kind of zirconia denture color card standard sample, preparation method and application method

Abstract

The invention relates to a zirconia denture color card standard sample, a preparation method and a use method. A dense gradient nanostructure and a bionic tooth matrix are prepared by a hydrothermal method, a 3D-colloidal molding process and a surface layer coating process technology. The scale-like smooth surface structure of natural tooth enamel. The invention is made of zirconia material, which can directly transmit optical information such as the texture and transparency of zirconia repair materials, and at the same time, taking into account the effect of discoloration tooth covering, the design is more scientific and reasonable, and the colorimetric deviation caused by different materials can be eliminated; The use of bionic zirconia denture color scale can not only compare the texture of enamel, but also compare the texture of dentin, and accurately transmit the information of the optical texture inside the oral cavity; it is beneficial for the processing end to accurately obtain various information of the denture to be processed, so as to prepare a product that is consistent with the denture. Zirconia dentures with consistent colorimetric results.

Description

technical field [0001] The invention relates to a zirconia denture color card standard sample, a preparation method and a use method. Background technique [0002] Restoring or reconstructing the optical texture of natural teeth through dentures is an important part of oral restoration. The goals of this work are defined by the dentist in discussion with the patient, and the task of manufacturing the restorations is carried out by the fabricator, which usually works at a remote location from the surgeon. The method of information exchange between the processing factory and the doctor on the optical texture of the tooth and the optical texture restoration and reconstruction technology used by it should become the key to the failure of the restoration system. This communication is usually simplified as color comparison in the industry, that is, a set of color guides is used as a medium for optical texture communication. [0003] 1. Existing colorimetric methods and principle...

AI Technical Summary

Problems solved by technology

[0016] Due to its excellent physical and chemical properties and biocompatibility, zirconia materials have become the most commonly used materials in the field of oral restoration, but the defects in the preparation process of cutting ceramic blocks, the aesthetic effect (color, Translucency) often does not achieve the texture of natural teeth, so it is not used to prepare standard colorimetric samples
