“…On the other hand, chemical properties such as corrosion resistance are extremely important for long-term implantation. Zhou et al, 48 Wauthle et al, 44 and Xia et al 40 those of Ta implants prepared by conventional methods, such as casting and powder metallurgy methods. 48 Moreover, Wauthle et al compared the mechanical properties of am-Ta, commercial Ti, and Ti6Al4V, finding that Ti6Al4V was the strongest in terms of static loading.…”

“…The Ta powder used for AM must be spherical 40 ; recently, some investigators proposed a new method to prepare Ti-30Ta alloy powder based on AM, generally illustrated in Figure 5. The particle size distribution of the prepared Ti-30Ta spherical powder was relatively uniform, and the Ta content did not change with the variation of particle size, indicating that the chemical composition was stable.…”

“…The particle size distribution of the prepared Ti-30Ta spherical powder was relatively uniform, and the Ta content did not change with the variation of particle size, indicating that the chemical composition was stable. 40 The particle size of Ta powder for AM also plays a vital role in the fabrication of a successful am-Ta implant and should be neither too large nor too small; the particle size distribution should be relatively uniform. If the particle size is too large, given energy density is insufficient for completely melting the powders.…”

Tantalum has unique advantages as a biomaterial for repairing bone defects due to its outstanding bioactivity, excellent corrosion resistance, and mechanical properties. Ideal implants for bone repair should be of good biocompatibility and bioactivity, as well as ability to simulate the microstructure and mechanical environment of human bone tissues. Additive manufacturing can facilitate freedom of design for the macrostructure/ microstructure of bone implants with controlled mechanical properties; thus, this method has great potential. Additively manufactured tantalum implants provide a novel alternative for bone repair and are gaining increasing attention. This systematic review aims to comprehensively summarize the subsistent evidence from physicochemical, cellular, animal, and clinical studies on additively manufactured tantalum implants in repairing bone defects, for the first time. This work may provide researchers an essential grasp on the advances of additively manufactured tantalum implants.

“…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].…”

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 long term. Porous Ta has high wettability and surface energy that can facilitate adherence, proliferation and mineralization of osteoblasts. Meanwhile, low elastic modulus and high friction coefficient of porous Ta can effectively avoid stress shield effect, minimize marginal bone loss and ensure primary stability. Accordingly, the satisfactory clinical application of porous Ta based implants or prostheses are 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 patient who need specially designed implant 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.
