The part-art comment is certainly true. I have a 3D milled ceramic crown that was done years ago during the early days of the technology. It is absolutely great in every way, and has been since day 1. My wife went to the same dentist a few months later, another 3D milled ceramic crown. Same guy, same machine. The crown had an awful fit, was never right, and she had it replaced with a different technology within 6 months. Getting to three-9's reliability is hard for all of us.
