Research Progress of Additively Manufactured Porous Tantalum Orthopedic Implantable Material

Tantalum, as a high-performance biometallic material with bioaffinity, is widely used in bone structure reconstruction and bone function repair. Porous tantalum exhibits excellent mechanical properties, biological properties, as well as in vivo osseointegration and bone ingrowth performance, showing outstanding clinical treatment effectiveness. This review based on recent research of our team and combined with literature analysis, reviewed the latest research progress in additive manufactured porous tantalum materials, including fabrication processes, structural design and optimization, mechanical properties, biological properties (cell-material interactions), in vivo osseointegration and bone ingrowth capabilities, and clinical applications. In particular, additive manufactured porous tantalum materials and orthopedic implants allow for the precise design and regulation of three-dimensional interconnected biomimetic porous structures, excellent static and dynamic mechanical properties, and bone conduction and bonding abilities. These materials are easy to manufacture anatomically matched personalized products, with promising applications in the repair of bone defects and the treatment of bone diseases.
