What is the correct procedure regarding the shade selection of crowns?

The correct procedure for shade selection of crowns involves selecting the shade before starting the preparation. This approach is essential because the shade should be matched as closely as possible to the natural teeth being restored. When the tooth is prepared, its inherent color can be altered by factors such as the materials used and the lighting conditions present during the procedure. By choosing the shade initially—under optimal lighting conditions and with an unprepared tooth—the technician can ensure a more accurate match to the natural dental aesthetic.

In the context of dental procedures, the significance of shade selection becomes clear, as it greatly affects the outcome of esthetic restorations. Choosing the right shade at the right time helps avoid complications and ensures that the final result blends seamlessly with the surrounding teeth.
