Problems solved by technology

Although cast ceramics, glass-infiltrated alumina ceramics, dense polycrystalline alumina ceramics, and zirconia ceramics have been released and used clinically, the mechanical properties and processing properties of the obtained ceramic materials are often not compatible, which limits clinical In addition, in clinical use, patients have higher and higher requirements for aesthetics, so the prepared product has a small visual difference with other teeth in the human body to meet this requirement

Abstract

The invention discloses a mouth rehabilitation material and a preparation method thereof. The mouth rehabilitation material is prepared from, by mass, 0.6%-2% of cerium oxide, 0.8-3% of yttrium oxide, 1%-4% of borax, 2%-4% of sodium stannate, 3%-5% of silicon dioxide, 15%-24% of aluminum oxide and the balance zirconium oxide. The mouth rehabilitation material is directly subjected to injection molding to obtain a ceramic tooth part, the tensile strength is high, the linear expansion coefficient is small, the Rockwell hardness is high, the yield strength is high, the advantages of being high in hardness, strength and toughness and the like are achieved, that is, good mechanical performance and processability are achieved, and meanwhile more excellent corrosion resistance is achieved. In addition, the ceramic tooth part obtained through direct injection molding of the mouth rehabilitation material and the tooth body of the human body are equivalent in refractive index, the ceramic tooth part is closer to the teeth of the human body, and clinical use is more attractive.

Description

technical field [0001] The present invention relates to an oral restorative material. The invention belongs to the technical field of dental treatment. Background technique [0002] Oral restoration is mainly aimed at the treatment of tooth defects and tooth loss, such as inlays, full crowns, dentures, etc., and also includes the use of artificial restorations for the treatment of periodontal disease and maxillofacial tissue defects. It is an important part of stomatology. an important branch. [0003] The number of patients with tooth loss caused by dental caries, periodontitis and tooth damage in my country is as high as one-fifth to one-third of the total population. Therefore, it is undoubtedly very important to accelerate the development of oral restorative materials and products, relieve the pain of millions of patients, and reduce the burden of medical expenses, and it is also the call of social development. [0004] Because of its good biocompatibility, ceramic ma...
