Research investigates surface structures to enhance cell proliferation on biomaterial composites, indicating potential for better implant integration.
Alumina-toughened zirconia composites (ATZ) have attracted much attention in biomaterials such as artificial hip joints and implants. ATZ has excellent mechanical properties and is resistant to degradation at low temperatures. However, ATZ is bioinert, meaning that it does not bond with bone, which is a problem after implantation. In this study, we are searching for a surface that promotes cell proliferation and differentiation on ATZ. We are fabricating specimens with various surface roughness and shapes, and investigating their osteogenic properties and strength.
