2 different techniques for colour and shade matching of dental porcelain crown?
There are a number of different shade guides that dentists use, all can be affected by the ambient lighting in the operatory so that what looks good in the office doesn't look so good in daylight. Ask to see the shade they suggest and ask if it is possible to go to a window and check the shade in daylight. You can also ask for "custom shading" where you visit the dental laboratory that is making your crowns and they custom match to your existing teeth - some labs have a technician that will travel to your dentist's office for custom shading. There will be an extra charge for the customization but it is worth it as nobody's teeth are one even colour from gum to biting edge.
Reply:My dentist has a shade guide which he uses to match the shade of remaining teeth so the crown matches and dosen't look out of place!

There's more to making a crown look like a natural tooth than picking the right shade.





Natural teeth are covered in enamel, which is a translucent material. Crowns made of completely opaque porcelain will look fake as can be, even if they're the right shade.





Additionally, teeth are rarely uniform in color. They tend to be more translucent at the very edges (at least anterior teeth are), whiter towarad the biting surfaces, and more yellow toward the neck. Additionally, hypocalcified areas that appear more opaque white may be present at various places on the tooth. It's important to recreate all of these features on the crown if they are present on the adjacent teeth.





As far as simpy shade-matching, I use a regular old-fashioned shade guide and ambient light. Of course, I let the patient OK the shade before I sent it to the lab. There are also fancy-shmancy devices that measure the various colors in the patients adjacent teeth and spit out a shade for you to make the crown with. A complete waste of money, if you ask me.
