a bone graft done (I knew someone who had this done some years

That was the crowns and bridges before the final bridge was installed
onto the implants to give the bone-graft time to "knit"

No idea on the cost of this, but probably quite substantial.

Just over 1 million Forints, plus some cheap flights and hotels.
