牙科氧化锆陶瓷半透明性的影响因素及提高方法的研究进展

Translucency of dental zirconia ceramic restoration

氧化锆陶瓷全瓷修复体因其拥有良好的力学性能越来越成为更多人修复后牙牙体缺失缺损的选择,但因其半透明性较差,较少被选择用于前牙修复。影响牙科氧化锆陶瓷半透明性的因素包括:陶瓷粉体直径、烧结温度、气孔率等。学者们通过调节氧化锆陶瓷的制作方法来提高半透明性。本文就牙科氧化锆陶瓷半透明性的影响因素及提高半透明性的研究等方面做一综述。

Zirconia all-ceramic restorations for tooth defects are getting more popular due to their excellent mechanical properties, but are less selective for anterior tooth restoration due to poor translucency. Factors affecting the translucency of dental zirconia ceramics include： ceramic powder diameter, sintering temperature, porosity, etc. has been Scholars has been trying to improve the translucency of the zirconia restorations through adjustment of zirconia ceramic production methods. The article reviews the influencing factors of translucency of dental zirconia ceramics and the research on improving the translucency.
