A comment on Food additive titanium dioxide likely has more toxic effects than thought.

What could this mean for dental or orthopedic titanium implants? From my understanding these also corrode at a small rate and release titanium ions into the body (nothing is apparently perfectly inert). I assume titanium ions oxidize and will result in titanium dioxide particles deposited across the body. So far, it has been said to be non toxic, but if research is coming out about toxic effects from food consumption route, could this have implications for people living with implants long term?

I suspect the dose is rather different.

This is one reason why zirconia implants are probably preferable for many uses. But for whatever reason they haven’t caught on.

Yes, they release particles in your body and this seem to cause issues for at least some people. But if there is a long time span between getting the implant and chronic health issues appearing I don't think people will be able to pinpoint that titanium implants might be the cause.

There are limited publications about the possible effect of titanium implants, for example https://pubmed.ncbi.nlm.nih.gov/30174768/

I’m not quite sure how to look this up, but what’s the downside to stainless steel? I know titanium and bone can actually “grow together” so titanium is sometimes better / worse for type of implants.

(I mainly ask as I have a rather large stainless steel plate in my left arm- which I hope to never need to have removed… but the fact they can be removed prompted a comical conversation with my partner about re-using medical implants)
