摘要：

氧化锆陶瓷凭借其优异的机械性能和良好的生物相容性，在口腔修复领域应用广泛。目前，基于计算机辅助设计和计算机辅助制造的切削工艺是氧化锆陶瓷修复体制造的金标准，但存在材料浪费和加工限制等局限性。相比之下，3D打印技术在材料利用率、复杂结构成型等方面展现出显著优势，为口腔修复体的制备提供了新的技术路径。在3D打印氧化锆陶瓷的制备过程中，打印方向作为关键工艺参数之一，显著影响其最终性能。目前，尚未见关于打印方向对3D打印氧化锆陶瓷性能影响和作用机制的归纳总结。因此，本文重点探讨了打印方向对氧化锆陶瓷机械性能、微观结构及尺寸精度等方面的影响，以期为修复体制备过程中合理选择打印方向提供理论依据。

Abstract:

Zirconia ceramics have been widely used in prosthodontics due to their excellent mechanical properties and biocompatibility. Presently, milling based on computer aided design and computer aided manufacturing remains the gold standard for producing zirconia ceramic restorations, yet it has certain limitations such as material waste and processing constraints. 3D printing offers a new solution for the production of dental restorations, leveraging its advantages in mate-rial utilization and fine structure processing. The printing orientation is a key parameter which can significantly affect the performance of the definitive zirconia restorations/ceramics. The existing literature has not yet systematically summarized the influence of printing orientation on the performance of 3D printed zirconia ceramics or its mechanisms. Therefore, this paper elucidates the influence of printing orientation on the mechanical properties, microstructure, dimensional accuracy, and other aspects of zirconia restorations/ceramics, aiming to provide a theoretical basis for rationally selecting the printing orientation during prosthesis fabrication.

Key words: zirconia, 3D printing, printing orientation, mechanical properties, microstructure, dimensional accuracy
