Abstract: Zirconia all-ceramic material is widely used for its excellent clinical performance，and the traditional processing method is mainly computer aided design and computer aided manufacturing（CAD/CAM）milling. With the development of additive manufacturing，3D printing technology has significantly improved the efficiency of manufacturing and degree of personalization of oral prosthesis，and has become a new technical hotspot. Numerous studies have confirmed that 3D printed zirconia all-ceramic prostheses meet the clinical requirements in terms of precision，biocompatibility，and crown margin suitability，and have the potential to be applied in clinical practice. However，further studies are still needed in terms of process optimization，material properties and long-term clinical effects，and the corresponding technical parameters，industry standards and clinical application guidelines need to be perfected. This review describes the research progress on the material type，technical characteristics and clinical performance of 3D printed zirconia all-ceramic crowns，analyzes their clinical feasibility，and predicts the future direction of development and key points of technological breakthroughs，aiming to better serve the clinical work.
