For 10 years, clinicians have been able to provide patients with a proven aesthetic and functional restoration that exhibits wear-compatibility, durability, and marginal integrity. This leucite-reinforced, pressed ceramic (IPS Empress, Ivoclar Williams, Amherst, NY) presents to patients and dentists the option of a metal-free alternative which retains the functional advantages of a porcelain-fused-to-metal restoration. This article illustrates the importance of sound laboratory communication in the utilization of this restorative material, focusing upon three aspects: midline and incisal edge inclination, elimination of open gingival embrasures, and incisal edge translucency. Techniques are also presented in order to efficiently communicate details of each case presented to the laboratory.
十年来，临床医生一直能够为患者提供一种经过验证的美观且功能良好的修复体，该修复体具有磨损兼容性、耐用性和边缘完整性。这种白榴石增强的压铸陶瓷（IPS Empress，义获嘉威兰德公司，纽约州阿默斯特）为患者和牙医提供了一种无金属替代方案，它保留了烤瓷熔附金属修复体的功能优势。本文阐述了在使用这种修复材料时良好的实验室沟通的重要性，重点关注三个方面：中线和切缘倾斜度、消除龈端间隙以及切缘透明度。文中还介绍了一些技巧，以便有效地向实验室传达每个病例的详细信息。
