Thus, metallic implants based on Ti (Ti6Al4V), Co-Cr alloys, and stainless steel (SS316L) have been used for more than a decade by clinicians for orthopedic reconstruction. However, a strong mismatch between the elastic moduli and tensile strengths of these metals and natural bone causes stress shielding effects resulting in the weakening and consequent fracture of the surrounding bone.
