“…The analysis revealed that 3Y-ZrO 2 powder comprised both tetragonal and monoclinic phases at a volume content of 68% and 32%, respectively, Table 2. After the sintering process, the tetragonal phase was predominant (around 100%), whereas the monoclinic one markedly decreased [41]. Moreover, the peak (101) remained unboarded, implying that there was no presence of other phases (such as the rhombohedral one) [42].…”

Polymer-infiltrated ceramic network (PICN) materials have gained considerable attention as tooth-restorative materials due to their mechanical compatibility with human teeth, especially with computer-aided design and computer-aided manufacturing (CAD/CAM) technologies. However, the designed geometry affects the mechanical properties of PICN materials. This study aims to study the relationship between manufacturing geometry and mechanical properties. In doing so, zirconia-based PICN materials with different geometries were fabricated using a direct ink-writing process, followed by copolymer infiltration. Comprehensive analyses of the microstructure and structural properties of zirconia scaffolds, as well as PICN materials, were performed. The mechanical properties were assessed through compression testing and digital image correlation analysis. The results revealed that the compression strength of PICN pieces was significantly higher than the respective zirconia scaffolds without polymer infiltration. In addition, two geometries (C-grid 0 and C-grid 45) have the highest mechanical performance.
