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
