ABSTRACT With the recent rapid development of the additive manufacturing family of technologies, the interest in application potential of stereolithography on producing ceramic dental prostheses has aroused and been widely discussed. While someone claimed the birth of ‘stereolithography-fabricated ceramic dental prostheses’, an overall evaluation based on the clinical requirements is lacking, making the optimism a kind of unrealistic. In this article, the prototypes of ceramic dental prostheses and standard specimens produced by the ceramic stereolithography approach are compared with those made by the classic subtractive manufacturing method by following the critical clinical requirements. Concerns on the upcoming challenges and future improvement towards clinical applications are presented that include productivity, delivery time, dimensional tolerance, mechanical and aesthetic properties. It is concluded that it is far too early to call ‘stereolithography-fabricated ceramic dental prostheses’ as a success as usable and competitive products for clinical applications.

立体光刻制作的氧化锆义齿：基于临床要求的关注

摘要 随着近来增材制造系列技术的快速发展，立体光刻技术在陶瓷义齿生产中的应用潜力引起了人们的广泛关注。虽然有人声称“立体光刻制作陶瓷假牙”的诞生，但缺乏基于临床需求的整体评估，使乐观变得有些不切实际。在本文中，根据关键的临床要求，将通过陶瓷立体光刻方法生产的陶瓷假牙和标准标本的原型与通过经典减材制造方法制造的原型进行了比较。提出了对即将到来的挑战和未来临床应用改进的担忧，包括生产力、交付时间、尺寸公差、机械和美学特性。得出的结论是，将“立体光刻制造的陶瓷假牙”称为临床应用中可用且具有竞争力的产品的成功还为时过早。
