摘　　要：基于计算机辅助设计/计算机辅助制作技术制作的全解剖式氧化锆冠具有出色的机械性能和生物学性能。相比传统氧化锆冠,它无需上饰瓷,降低了崩瓷的风险,且所需的牙体预备量更小。早期使用的全锆冠半透性低,外观呈白色,美观性能不足。随着透明氧化锆的发明以及氧化锆染色技术的发展,全锆冠的美观性得到很大提高,使其在美学修复中得到更广泛的应用。但这种美观性能提高以后的全锆冠最终呈现的修复效果往往还受多种临床因素影响,如低温老化、基牙颜色、全锆冠的厚度、全锆冠表面抛光、黏固材料的类型和颜色等。本文就影响全锆冠美学修复效果的因素作一综述。Monolithic zirconia crowns fabricated by computer-aided design/computer-assisted manufacturing equipment possess extraordinary mechanical properties and excellent biocompatibility.Unlike traditional zirconia crowns,monolithic zirconia crowns eliminate the veneering ceramic layer’s need,which reduces the risk of veneering ceramic chipping and the required tooth reduction.Traditional zirconia is poor in aesthetic performance because of its inherent whitish color and high opacity.Recently,improved translucency and various coloring technologies have dramatically improved the aesthetic performance of monolithic zirconia crowns and vastly broadened the range of its applications in prosthetic dentistry.However,the final prosthesis performance of monolithic zirconia crowns is often affected by various clinical parameters,such as dental background,dental crown thickness,cement,surface finishing protocols and low-temperature degradation.This paper reviewed the factors influencing the aesthetics of monolithic zirconia crowns to assist the selection of monolithic zirconia crowns for dentists.
