Oh hell where do i start.. I practically grew using vita porcelan and ordered 3d shades in 1999. Ordered the Bleachedguide
3D Master when it came out thinking i could match interpolated shades (intermediate shades) a little easier.
Best advice i can give is to start taking detailed notes on every shade you make in zirconia. Second tip, Value comes first.
Unfortunetly zirconia shades still aren't perfect and value is the huge problem your going to have with 3D shades.
Lighter/higher value core shades and white zirconia must be used to match light 3D shades. You may quickly learn you may need to change
brands of zirconia or milling labs. After trying many brands of porcelain I've had better results using GC porcelain with their 3D conversion chart on zirconia as compared to using VM9 and CZR as far as matching 3D shades. I'm still using InSyn and Creation CT porcelain and taking notes..
Good luck with your new science project... lol
