In dentistry, the concept of realism can be applied to the creation of an artificial prosthesis that is not perfect, but real. If prosthesis are made to a flawless perfection, they will appear artificial. Ultimately, the clinician and ceramist should strive for realism. The IPS Empress System (Ivoclar Williams, Amherst, NY) is an all-ceramic restorative alternative utilizing a pressable leucite-reinforced glass ceramic for a variety of indications (e.g., crowns, inlays/onlays, veneers). The resulting tooth-colored and metal-free restorations combine strength and aesthetics approaching those of natural teeth. This article describes the technique and procedures required to achieve realistic anterior crowns with this all-ceramic system.
在牙科领域，逼真性的概念可应用于制作虽不完美但逼真的人工修复体。如果修复体制作得完美无缺，它们会显得很假。最终，临床医生和陶瓷技师应追求逼真性。IPS Empress系统（义获嘉威兰德，纽约州阿默斯特）是一种全瓷修复体替代方案，它使用可压铸的白榴石增强玻璃陶瓷，适用于多种适应症（如牙冠、嵌体/高嵌体、贴面）。由此产生的牙齿颜色且无金属的修复体结合了接近天然牙齿的强度和美观性。本文描述了使用这种全瓷系统制作逼真前牙冠所需的技术和步骤。
