Introduction
• In the past prostheses were made
of wood and metal -heavy and
uncomfortable
• Goal: show how materials science
solve these problems
• Plan: light materials, bone
connection, infection protection

3.

Light materials
• Carbon fibre is five times lighter
than steel but just as strong.
• It works like a spring, storing and
releasing energy during walking.
• Titanium is light, rust-proof, and
causes no allergies.

4.

Connection to bone
• Osseointegration means a titanium
implant placed directly inside the
bone.
• Bone cells grow onto the rough
titanium surface — they become
one.
• Calcium phosphate coating speeds
up healing because it is the same
mineral as real bone.

5.

Fighting infections
• Bacteria form a sticky biofilm that is
hard to remove.
• Silver nanoparticles kill bacteria
without harming human cells.
• Hydrophobic surfaces repel water —
bacteria cannot grow without water.

6.

Conclusion
• Three breakthroughs: light
materials, bone connection,
infection protection.
• A good prosthesis is not only
about shape — it is about
choosing the right material.
