Ceramics has become increasingly popular as a dental restorative material because of its superior esthetics, as well as its inertness and biocompatibility. Among dental ceramics, zirconia is used as a dental biomaterial and it is the material of choice in contemporary restorative dentistry. Zirconia ceramics has both clinical popularity and success due to its outstanding mechanical properties and ease of machining in the green stage via computer-aided design and computer-aided manufacturing technology. Zirconia is one of the most promising restorative biomaterial because it has favorable mechanical and chemical properties suitable for medical application. Zirconia ceramics is becoming a prevalent biomaterial in dentistry. Clinical evaluations also indicate a good success rate for zirconia with minimal complications. This article reviews the current literature on dental zirconia with respect to basic properties, biocompatibility, and clinical applications in aesthetic dentistry as single unit crown.
由于其卓越的美学性能、惰性和生物相容性，陶瓷作为一种牙科修复材料越来越受欢迎。在牙科陶瓷中，氧化锆被用作牙科生物材料，是当代修复牙科的首选材料。氧化锆陶瓷因其出色的机械性能以及在坯体阶段通过计算机辅助设计和计算机辅助制造技术易于加工，在临床上广受欢迎且取得了成功。氧化锆是最有前途的修复生物材料之一，因为它具有适合医学应用的良好机械和化学性能。氧化锆陶瓷正在成为牙科中一种普遍使用的生物材料。临床评估也表明氧化锆的成功率很高，并发症极少。本文综述了目前关于牙科氧化锆的文献，内容涉及基本性能、生物相容性以及在美学牙科中作为单冠的临床应用。
