And gold is not a good bone-facing material, because bone doesn't fuse with it.
Titanium is favored for implants because it supports osseointegration.

Doh, yeah: TSA! Titanium Shock Absorber:
So this entire subthread about implanted teeth rigidly connected to the bone is about mainstream technology, not the state of the art.
I wouldn't be surprised if this can, over time, also cause damage to your jaw, and put extra stress on your jaw muscles.
I have four implants, two in my lower jaw, two in my upper jaw. My lower jaw is basically stone, an extremely hard bone even by usual lower jaw standards; the dentists (plural, as one was unable to finish the job) drilling into it destroyed a few drilling bits doing so. I have never had any problems with the lower jaw implants. That bone can take almost anything in stride.
My upper jaw, on the other hand ... very delicate, just enough bone left for the implants to work, and I learnt to be careful about biting into anything harder with them.
