Fabricating all-ceramic restorations with minimal or no application of a secondary phase while maintaining esthetics has been a sought-after goal of the dental profession. The objective has been development of a monolithic material with optical properties similar to the natural tooth without the need for layering porcelain. This article examines some of the newer cubic zirconia materials used in a monolithic form. The authors discuss laboratory-processing issues that affect esthetics, including evaluation of colorizing, sintering, finishing, and polishing, and assess initial translucency testing of several materials while evaluating the effect of air abrasion on flexural strength of these cubic zirconias. Lastly, the article demonstrates an anterior single-unit monolithic case with several of the newer materials.
在保持美观的同时,制造最少使用或不使用第二相的全瓷修复体一直是牙科行业追求的目标。目标是开发一种具有与天然牙齿相似光学性能的整体材料,而无需分层堆瓷。本文研究了一些以整体形式使用的新型立方氧化锆材料。作者讨论了影响美观的实验室加工问题,包括着色、烧结、修整和抛光的评估,并在评估空气喷砂对这些立方氧化锆弯曲强度的影响时,对几种材料进行了初始透明度测试。最后,本文展示了一个使用几种新型材料的前牙单冠整体修复病例。
