牙科材料耐磨损性能的影响因素

Influential factors of the abradability of dental materials

口腔修复材料在口内代替天然牙长期行使咬合功能,咀嚼过程即是修复材料和天然牙的磨损过程。耐磨损性能是选择牙科材料的重要因素。由于口腔咀嚼过程和环境的复杂性,修复材料的耐磨损性能受诸多因素影响。本文就牙科材料耐磨损性能的主要影响因素作一综述。

Dental prosthetic restorations replace natural teeth with occlusal function for years in vivo, and the process of chewing is the wear of themselves and natural teeth. The abrasion resistance is the important factor when one chooses dental restorative materials. As the complexity of process of chewing and the oral environment, many factors effect abradability. The main influential factors of abrasion resistance are reviewed in this article.
