Do you mean that it costs a patient USD1800 to get a crown?
I have two crowns both made and installed at the same dental practice in Drammen, Norway, using, I think, the CEREC system. At one time he had a screen mounted above the couch so that you could see it being shaped while you waited.
Including the initial consultation, the crown itself, and the fitting I paid about NOK5000 each. That's about USD580 at today's exchange rate, about USD750 at the rate that was in force when I had them done.
