Metal implants play a crucial role in biomedical engineering, offering durability and reliability for bone reconstruction.
With superior mechanical properties compared to ceramics and polymers, metals like Titanium Ti-6Al-4V (Gr.5) ELI are preferred for handling heavy loads. In fact, 80% of implants are made from metal, with Titanium Ti-6Al-4V (Gr.5) ELI being the major choice, especially due to its higher fatigue strength and fracture toughness.
The value of the Elastic Modulus / Young's Modulus, should closely match that of the bone to minimize the stress-shielding effect between the bone and the implant. We will delve into more details about the stress-shielding effect in our next post.
Ti-6Al-4V ELI closely matches bone's Young's modulus as compared to other metallic implantable materials, making it a top choice for bone replacements.
