This article presents a brief history of dental ceramics and offers perspectives on recent research aimed at the further development of ceramics for clinical use, at their evaluation and selection, and very importantly, their clinical performance. Innovative ceramic materials and ceramics processing strategies that were introduced to restorative dentistry since the early 1980s are discussed. Notable research is highlighted regarding (1) wear of ceramics and opposing enamel, (2) polishability of porcelains, (3) influence of firing history on the thermal expansion of porcelains for metal ceramics, (4) machining and CAD/CAM as fabrication methods for clinical restorations, (5) fit of ceramic restorations, (6) clinical failure mechanisms of all-ceramic prostheses, (7) chemical and thermal strengthening of dental ceramics, (8) intraoral porcelain repair, and (9) criteria for selection of the various ceramics available. It is found that strong scientific and collaborative foundations exist for the continued understanding and improvement of dental ceramic systems.
本文介绍了牙科陶瓷的简史，并对近期旨在进一步开发临床用陶瓷、评估和选择陶瓷，以及非常重要的陶瓷临床性能的研究进行了展望。讨论了自20世纪80年代初引入修复牙科的创新陶瓷材料和陶瓷加工策略。重点介绍了关于以下方面的显著研究：（1）陶瓷与对颌牙釉质的磨损；（2）瓷的可抛光性；（3）烧制历史对金属烤瓷热膨胀的影响；（4）加工以及CAD/CAM作为临床修复体的制作方法；（5）陶瓷修复体的密合度；（6）全瓷修复体的临床失败机制；（7）牙科陶瓷的化学和热强化；（8）口腔内瓷修复；（9）各种可用陶瓷的选择标准。研究发现，在持续理解和改进牙科陶瓷系统方面，存在强大的科学和协作基础。
