钛具有良好的机械性能、耐腐蚀性及生物相容性,且资源广泛、价格低廉,是理想的口腔修复材料。但由于钛化学性质活泼,高温下易与空气中的碳、氢、氧、氮及包埋材中的多种元素发生反应,给钛的铸造技术带来诸多不便。80年代初期,随着齿科专用铸钛机及配套材料的开发研制,使该项技术得以在口腔修复中应用,并取得良好效果。近年来,众多学者在此技术基础上进一步开发研制新的材料及工艺并应用于临床。本文就此类研究进展作一综述。
Titanium has good mechanical properties, corrosion resistance and biocompatibility, and wide range of resources, low prices, is the ideal oral repair materials. However, due to the active chemical properties of titanium, high temperature easily with the air of carbon, hydrogen, oxygen, nitrogen and embedded in a variety of elements in the reaction, to the titanium casting technology brings a lot of inconvenience. In the early 1980s, with the development and manufacture of dental special titanium casting machines and supporting materials, the technique was applied to oral repair and achieved good results. In recent years, many scholars based on this technology to further develop new materials and processes and applied to clinical. This article reviews the progress of such research.
