Tof mentioned about the shade verification procedure and how it works in previous articles. Now let’s see how it is practiced clinically.
First of all, let’s see who needs a system like this.
Since this system is designed to avoid the troubles that a patient has to come back and forth for a shade mis-matched crown. (Remakes due to shade also sometimes caused the loss of faith of the patients on the dentist, tof has heard a true story in the clinic I used to worked for. A patient lost her patience on the never-ending process of changing shades. She took the crown out of her mouth, threw it on the floor and yelled: “I am done with this nonsense!” And then she turned around and stormed out of the clinic.)
