when some foreign particle enters the human body then immune system reacts to it and tries to destroy it, be it anything even an organ from another person. Why immune system does not react to titanium plates-that are attached to fix the broken bones?

Question

I got a titanium plate screwed in my lower jaw that got broken previously. I recently read somewhere that immune system attacks every foreign particle, even transplanted organs that’s why one has to be on immunosuppressants to live with transplanted organs.

Answer 1

organs are biological. If they are not genetically yours the body deems them invasive. Titanium forms a strong oxide coating that prevents it from reacting with pretty much anything. This makes it nearly invisible to the body. Other biocompatible substances are similarly ignored by the bodies defenses.
