Preparation, modification, and clinical application of porous tantalum scaffolds. [PDF]
Front Bioeng Biotechnol, 2023 Porous tantalum (Ta) implants have been developed and clinically applied as high-quality implant biomaterials in the orthopedics field because of their excellent corrosion resistance, biocompatibility, osteointegration, and bone conductivity. Porous Ta allows fine bone ingrowth and new bone formation through the inner space because of its high porosity
