“…There has been a recent trend in using alloys of titanium and tantalum to benefit from the best features of both materials. [199][200][201] However, most studies have been limited to solid specimens so far and thorough studies of porous structures made from these alloys are still lacking.…”

“…Named after the Greek mythological figure Tantalus [ 1 ], tantalum or Ta is a rare, rigid and ductile metal element with an extremely high melting point (3017 °C) [ 2 ] and density (16.6 g/cm 3 ) [ 3 , 4 ]. Ta has excellent biocompatibility and corrosion resistance, has been used in pacemaker electrodes, suture wire, cranioplasty plates, radiopaque markers, foil and mesh for nerve repair since the 1940s [ 5 ].…”

The Clinical Application of Porous Tantalum and Its New Development for Bone Tissue Engineering

Porous tantalum (Ta) is a promising biomaterial and has been applied in orthopedics and dentistry for nearly two decades. The high porosity and interconnected pore structure of porous Ta promise fine bone ingrowth and new bone formation within the inner space, which further guarantee rapid osteointegration and bone–implant stability in the long term. Porous Ta has high wettability and surface energy that can facilitate adherence, proliferation and mineralization of osteoblasts. Meanwhile, the low elastic modulus and high friction coefficient of porous Ta allow it to effectively avoid the stress shield effect, minimize marginal bone loss and ensure primary stability. Accordingly, the satisfactory clinical application of porous Ta-based implants or prostheses is mainly derived from its excellent biological and mechanical properties. With the advent of additive manufacturing, personalized porous Ta-based implants or prostheses have shown their clinical value in the treatment of individual patients who need specially designed implants or prosthesis. In addition, many modification methods have been introduced to enhance the bioactivity and antibacterial property of porous Ta with promising in vitro and in vivo research results. In any case, choosing suitable patients is of great importance to guarantee surgical success after porous Ta insertion.

“…In addition, Ta has been used as single or composite coating material to modify the biological and mechanical properties of pure titanium(Ti) [6][7][8], Ti alloy (Ti6Al4V) [9], polyetheretherketone (PEEK) [10], cobalt-chromium (CoCr) alloy [11,12], magnesium-based alloy [13], pure Fe [14] and 316L stainless steel [15]. Recently, the advent of Ti-Ta alloy with different Ta element content indicates a novel way to fabricate implants for bone defects restoration with improved mechanical strength, satisfactory elastic modulus and biological properties compared to pure Ti and Ti alloy [2,16,17].…”
