摘　　要：氧化锆修复体临床应用可以分为两种主要形式:一是氧化锆基底加饰瓷的双层复合结构,二是单层全氧化锆修复体(全解剖氧化锆)。这种单层氧化锆材料如何在保证机械强度的同时提高全解剖氧化锆修复体美学性能,始终是临床研究的热点之一。本文将介绍氧化锆材料因素、制作因素、临床因素对全解剖氧化锆修复体颜色及透明度的影响,对氧化锆材料同色异谱现象及低温老化对其美学性能的影响进行分析阐述,以利于口腔临床更好地应用全解剖氧化锆修复体。The clinical application of zirconia restorations can be divided into two main categories:the bilayer composite structure(zirconia-based with veneering ceramic)and the monolithic zirconia restoration(full-contour zirconia).It has always been one of the focuses of clinical researches that how the monolithic zirconia materials improve the aesthetic properties of full-contour zirconia restorations and ensure their mechanical strength.This article introduces the factors influencing the color and translucency of full-contour zirconia restorations from the aspects of material factors,manufacturing factors,and clinical factors,and analyses the effect of metamerism and low temperature degradation on the aesthetic properties of zirconia material for better clinical application of full-contour zirconia restoration in density.
