The search for tooth-colored and metal-free restorations is one of the major challenges in dental research. For several decades, ceramic has been used as a restorative material because of its aesthetics and stability. Unfortunately, the survival rate of most all-ceramic systems seems unsatisfactory; due to the natural brittleness of ceramic, fractures have been the primary reason for the high failure rate. Since 1988, the University of Zurich Dental School, Switzerland, has been working with the IPS Empress all-ceramic system (Ivoclar/Williams, Amherst, NY). This article reports the clinical and research data from approximately 3,000 all-ceramic restorations.
寻找牙齿颜色且无金属的修复体是牙科研究中的主要挑战之一。几十年来，陶瓷因其美观性和稳定性一直被用作修复材料。不幸的是，大多数全陶瓷系统的生存率似乎并不理想；由于陶瓷天然的脆性，骨折一直是高失败率的主要原因。自1988年以来，瑞士苏黎世大学牙科学院一直在使用IPS Empress全陶瓷系统（义获嘉/威廉姆斯，纽约州阿默斯特）。本文报告了约3000例全陶瓷修复体的临床和研究数据。
