摘要
我们探索了含有复合氧化物固体 Zr1-n[YbNd]nO2 溶液和刚玉微相的陶瓷材料的物理和机械性能,以及其在牙科修复实践中满足美学和强度要求的潜在用途。结果表明,这种陶瓷的静态抗弯强度为 850 兆帕。根据国际标准 ISO 6872:2015 "牙科-陶瓷材料",该材料属于第四和第五类。因此,这种材料不仅可以用于制作单个牙冠,还可以用于制作四单位桥体,且不受定位和固定的限制。新型陶瓷符合修复牙科的要求,具有所需的颜色特征和高不透明度,可以遮盖支撑结构。
Ceramic Materials Based on a Complex Oxide Solid Solution of a Tetragonal Form of Zirconia: Application in Prosthetic Dentistry
We explored the physical and mechanical properties of ceramic material containing complex oxide solid Zr1– n[YbNd]nO2 solution and corundum micro phase and its potential use in prosthetic dentistry practice meeting aesthetic and strength requirements. The ceramic obtained is shown to have a static bending strength of 850 MPa. According to the international standard ISO 6872: 2015, “Dentistry–Ceramic Materials,” the materials belong to the fourth and fifth class. This makes it possible to apply the material not only for making single crowns but also to manufacture four-unit bridgework having no localization and fixing restrictions. The new ceramics meet the requirements set forth in prosthetic dentistry and feature required color characteristics and has high opacity which makes it possible to mask the supporting structures.
期刊介绍:
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
