The blade or cylinder embedded into the bone during the first surgery is usually made of what material?

• A. Aluminum
• B. Titanium
• C. Stainless steel
• D. Ceramic

Answer: (B)

Biocompatibility and the ability to bond with bone drive material choice for implants. Titanium is ideal because it forms a stable, protective oxide layer that resists corrosion in the body and minimizes inflammation. Its surface supports osseointegration, allowing bone to grow onto and around the implant for solid fixation. Titanium also offers a favorable strength-to-weight ratio and a modulus of elasticity closer to bone, reducing stress shielding. Aluminum isn’t used for implants due to poorer long-term biocompatibility and corrosion concerns in bodily fluids. Stainless steel, while strong, can corrode and release ions over time and doesn’t promote bone integration as effectively as titanium. Ceramics are very hard but brittle, making them susceptible to fracture under functional loads, which isn’t ideal for components embedded in bone.
