摘要

Titanium and its alloys are favored as substrates for orthopedic implants due to their exceptional mechanical properties, robust corrosion resistance, and favorable biocompatibility. Nonetheless, the relatively high modulus of elasticity and intrinsic biological inertness of titanium impede effective osseointegration and compromise the long-term stability of these implants in the human body. To address these limitations, this review examines the synergistic application of additive manufacturing processes and surface modification techniques. The paper outlines the production of porous titanium alloys for orthopedic applications through additive manufacturing and evaluates current surface modification methods aimed at enhancing the implants’ biocompatibility and mechanical congruence with bone tissue.
