Tantalum metal (Tantalum, Ta), excellent corrosion resistance, and has the characteristics of high melting point, strength, wear resistance, are widely used in refractory material, including aircraft, rockets, and need high strength parts industry. In addition, the metal tantalum has good physical and mechanical properties, good biological compatibility, performance after titanium became a new type of biological materials, is widely used in dental implant implantation, treatment of femoral head necrosis, coronary stenting, artificial acetabulum prosthesis implantation, surgical sutures and other related medical field.
In recent years, with the deepening of the research on metal tantalum, it was found that porous tantalum with human cancellous bone approximate cellular stereo structure, with low elastic modulus and high friction properties, therefore, porous tantalum and is referred to as "tantalum bone" (Tantalumbone).This paper will introduce the research progress of structural mechanics properties, biological characteristics, surface modification techniques of tantalum and porous tantalum, and introduce the current research status in the field of oral medicine.
