Abstract

A method for manufacturing an anti-inflammatory dental restoration material with layers of self-assembled coatings relates to a manufacturing method for a dental restoration material. The purpose of the present invention is to solve the problems that the existing zirconia ceramics have high brittleness and low fracture toughness, and are prone to fracture, chipping and no anti-inflammatory properties as tooth restoration materials. Methods: 1. Prepare solution A; 2. Prepare slurry; 3. Prepare ceramic block; 4. Sinter; The fracture toughness of the anti-inflammatory tooth repair material with layers of self-assembled coatings prepared by the invention is improved by 1 to 1.5 times compared with zirconia ceramics. The present invention can obtain an anti-inflammatory dental restoration material with layers of self-assembled coatings.

Description

technical field [0001] The present invention relates to a method for the manufacture of dental restorative materials. Background technique [0002] A tooth is a structure found in many vertebrates, humans and higher animals for chewing food. Teeth are the hardest organ in the human body. Generally speaking, teeth are white and hard in texture. The various shapes of teeth are suitable for many purposes, including tearing, grinding food. Once the tooth is damaged, it needs to be repaired. Therefore, the repair material is one of the key contents in the field of dentistry. [0003] At present, dental restoration materials have gradually developed from initial resin to metal, and finally to zirconia denture materials. Zirconia ceramic materials have good comprehensive properties such as high melting point, high hardness, high wear resistance, and oxidation resistance. The source is sufficient, the manufacturing cost is low, and it is suitable for large-scale industrial produ...
