Resumen:
This study explores the rheological properties of zirconia-based ceramic
inks, focusing on TZ-3YSB alongside newer variants such as Zpex, Zpex-4,
and Zpex-smile, distinguished by their varying Y2O3 content. Through
comprehensive analysis, it was found that these ceramic inks exhibit
non-Newtonian behavior, which is notably influenced by the ceramic
loading content and particle aggregation. Moreover, the shear-thinning
nature observed in these inks proves advantageous, as it enables easier
extrusion through smaller nozzles at reduced pressure levels. The
implications of these findings are discussed in detail, shedding light
on the complex interplay between rheological properties and ceramic ink
composition, thus offering valuable insights for optimized
threedimensional printing (3DP) production processes - contributing to
strengthening crowns, bridges, and implants, enhancing aesthetics, and
ensuring biocompatibility for dental prostheses.
