Biocompatible 3D printed yttria-stabilized zirconia parts using direct ink writing Buj Corral, Irene Sanz Fraile, Héctor Tejo-Otero, Aitor Vidal, Daniel Padilla Sanchez, Jose Antonio Xuriguera Martín, María Elena Otero Diaz, Jorge Materials biomèdics Materials refractaris Biomedical materials Refractory materials Metals such as titanium or Cr-Co alloys have been the most widely used materials in biomedical applications that requirehigh mechanical properties, like implants. However, these materials present the disadvantage of releasing ion metals intothe body. As an alternative, prostheses made of ceramic materials have been developed, as they produce less debris andhave better durability. The aim of the present work is to test the biocompatibility of 3D-printed yttria-stabilized zirconia</p><p>parts by culturing human bone-marrow-derived mesenchymal stem cells. Two different scaffols were 3D printed having a</p><p>liner infill pattern, with 80 % and 95 % infill rate respectively. Results on surface roughness and biocompatibility tests</p><p>confirmed that 3 mol % yttria-stabilized zirconia is a highly promising material as it presented high biocompatibility. In adition,</p><p>similar results were obtained with or without the use of a type I collagen coating., which suggest that coating couldbe avoided when on zirconia substraes. 2026-03-27T08:51:38Z 2026-03-27T08:51:38Z 2024 2026-03-27T08:51:38Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 0954-4054 https://hdl.handle.net/2445/228552 737639 eng Versió postprint del document publicat a: https://doi.org/10.1177/09544054231168469 Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2024 https://doi.org/10.1177/09544054231168469 (c) Professional Engineering Publishing (Institution of Mechanical Engineers), 2024 info:eu-repo/semantics/openAccess 10 p. application/pdf SAGE Publications Articles publicats en revistes (Biomedicina)
