How does Shade Guide work for us?
Simply knowing the correct colour will not provide a perfectly matching restoration. It's easier to understand where to place ceramic when fabricating a restoration if there is some visual input. This is why a photograph is used to help determine where colour changes occur. This information is invaluable for the technician to see colour shifts, regardless of whether or not a photograph is colour accurate.
When viewing shade guides, the colour differences can be visually detectable by 50% of human observers in controlled conditions when Delta E values are greater than one unit. The difference between 2.0 and 3.7 Delta E is visually detectable under clinical conditions.
The R-20 Shade Guide has 20 shade tabs with Delta E's close together and can be difficult for proper shade selection. It's also unable to produce all of the colours necessary in dentistry. The total R-20 Classical Shade Guide range has a coverage rated at 17 Delta E* divergence.
