Blue, that sort of BS is why I'm likely to still drive back to Indianapolis to the dentist I had there when I get two molar implants done. They invested in the hardware to not only take digital builds of your mouth (instead of the wax/clay/yuck impression), but they can design the replacement digitally and then, I shit you not, have a machine cut the replacement right then. I've had two crowns done and the entire process happens in one visit, over the course of maybe 3 hours. The machine is like a reverse digital printer, it takes a piece of material that looks like a sugar cube (which has been color matched to the surrounding teeth) and carves it into the digital model. There's no "oops it doesn't fit". They do implants with somewhat the same process, although there's bone grafting and whatnot that has to happen on prior visits first. But the actual implant is made on-site, "while u wait".
I imagine over the next ten years, more and more dentist offices will buy this stuff. It's streamlined their procedures amazingly. I sent my dad there when he needed a tooth crowned recently and he said "It's like I stepped twenty years into the future".
