| Abstract Scope |
Biomaterials such as artificial tooth roots and implants are used in high-load areas, requiring materials with excellent load-bearing capacity and biocompatibility. This study utilized alumina-toughened zirconia (ATZ) containing approximately 20% alumina by mass. ATZ is a biologically inert material that does not bond with bone after implantation, resulting in a higher initial failure rate and longer fixation time compared to conventional titanium implants. This study attempted to enhance the biocompatibility of titanium implants by controlling their surface properties. Furthermore, we envision the fabrication of monolithic zirconia implants utilizing these surface characteristics. Test specimens with unidirectional groove structures were fabricated using a liquid-tank photopolymerization 3D printer (VPP). The results showed that specimens with groove width, groove depth, and ridge width of 0.1 mm—scales close to the cellular level—exhibited the best cell differentiation potential and met ISO standards. |
