Abstract

The invention relates to a mouth rehabilitation ceramic material, comprising the following components in percentage by mass: 0.20-5.00% of Y2O3, 0.10-5.00% of HfO2, 0.10-6.50% of Al2O3, 0.80-2.70% of SiO2, and the balance of ZrO2. The mouth rehabilitation ceramic material has the excellent performance of ZrO2 ceramic, is good in biocompatibility, has excellent properties including high hardness, high strength, high tenacity, ultra-high abrasion resistance and chemical corrosion resistance and the like, and is good in processability and optical performance, and the refraction and scattering coefficients of the mouth rehabilitation ceramic material are similar to those of tooth body tissues, so that the transparency, color and luster of natural teeth can be reproduced. Besides, the mouth rehabilitation ceramic material is sintered into ceramic blocks in use and does not contain a metal material, so that gingival color changes and inflammation caused by the release of metal ions are avoided, and nuclear magnetic resonance and computed tomography examinations cannot be influenced.

Description

Technical field [0001] The invention relates to the field of dental restoration, in particular to an oral restoration porcelain material and its application. Background technique [0002] Dental disease is a common disease with a high incidence. Tooth defect and missing dentition are very common in dental diseases, and dentures are usually used for restoration. [0003] Porcelain teeth are a kind of commonly used dentures. Porcelain teeth are composed of an inner metal base layer and an outer porcelain layer. According to their metal base crown materials, they are divided into three categories: precious metal alloy porcelain crowns (gold alloys). Porcelain crowns are represented), non-precious metal alloy porcelain crowns (represented by nickel-chromium alloy porcelain crowns and dental restoration porcelain materials porcelain crowns), titanium alloy porcelain crowns. [0004] Porcelain teeth have the following problems in clinical use due to the existence of the internal metal ba...
