Los metales y la medicina

The video tutorial discusses the use of metals like titanium, stainless steel, and amalgams in medical applications. Titanium is favored for its reactivity with oxygen, forming a stable surface ideal for implants, and its non-magnetic nature makes it safe for MRI procedures. Stainless steel, an alloy of iron and chromium, is used for temporary bone reinforcement due to its density and oxidation resistance. Dental amalgams, composed of silver and mercury, are used for tooth fillings due to their moldability and durability.

Why is titanium considered suitable for use in hip replacements?

• It is cheaper than other metals.

• It forms a stable, non-reactive surface in the body.

• It reacts with body chemicals to strengthen bones.

• It is magnetic and can be easily detected.

What is a key advantage of titanium in medical applications?

• It oxidizes easily in the body.

• It is highly magnetic.

• It is lightweight and non-reactive.

• It is denser than stainless steel.

How does stainless steel differ from titanium in medical use?

• It is less dense and more reactive.

• It is denser and used for temporary reinforcement.

• It is magnetic and used in MRI machines.

• It oxidizes more easily than titanium.

What is the primary use of amalgams in dentistry?

• To create temporary bone reinforcements.

• To fill cavities in teeth.

• To replace hip joints.

• To make MRI machines.

What metals are typically found in dental amalgams?

• Gold and copper.

• Iron and chromium.

• Silver and mercury.

• Titanium and aluminum.
