CAD/CAM陶瓷材料的分类及研究进展

Abstract

Abstract: At present, the most commonly used dental CAD/CAM repair system is ceramic materials, which can be divided into rensin-matrix ceramics, polycrystalline ceramics and glass-matrix ceramics according to the composition differences. The composition of materials determines its characteristics. Different kinds of ceramics have great differences in mechanics and aesthetics. They are usually selected according to clinical needs and patients'needs. Each material has its own advantages and disadvantages, such as high transparency but brittle quality of glass-ceramics, high strength but low transparency of polycrystalline ceramics, rensin-matrix ceramics has both advantages of glass-ceramics and resin materials, but low strength. In this paper, the classification of their compositions, the characteristics of each type of ceramics and the research progress in recent years are reviewed systematically, which is helpful to guide clinical selection of CAD/CAM materials.

Key words: CAD/CAM, glass ceramic, polycrystalline ceramic, resin-ceramic composite
