AI and the Future of Bone Implants

Why do artificial hip replacements often need to be replaced after 10 or more years of use?

• The materials used are toxic to the human body

• The constant force of walking millions of steps wears the implant down

• The human body naturally dissolves the metal over time

• The implants are too light to stay in place

Engineered materials that have unusual properties because of their microscopic structure are known as " (a)   ."

What is unique about "auxetic" materials compared to a normal elastic band?

• They get thinner when they are stretched

• They turn into a liquid when they are compressed

• They get thicker when they are stretched

• They disappear when they are placed under pressure

Explain how using artificial intelligence (AI) helps scientists design new medical materials more efficiently than traditional methods.

Why are scientists designing bone implants with a porous, honeycomb-like structure?

• To make the implant as heavy as possible for stability

• To allow living cells to grow into the implant and help it integrate with the body

• To ensure the implant does not touch any real bone

• To make the implant easier to see on an X-ray
