Once the restoration has been created, preferably before the patient can see the restoration, the target-actual comparison between the desired and determined tooth shade and the shade of the restoration should take place in the laboratory and dental practice. For this, VITA recommends using the VITA Easyshade V. For optimal quality management, laboratories and dental practices should use the restoration shade determination of the VITA Easyshade V, set the desired target shade, measure and can inspect the accuracy of the reproduction of the patient's tooth shade directly on the touch display.
This is too easy to ignore this process step.
