Digital Photography � The quality of digital cameras has greatly advanced over the last few years and they have become much more affordable as well. Photos can be printed at the office and sent with the case or emailed to the lab. While they cannot be used for exact shade matching they are a great tool in providing the ceramist a visual picture of �what is going on with this shade�. Individual characterizations, amount of translucency, darker gingival 1/3, and check lines are now a more realistic goal instead of guess work. We would suggest a digital SLR with a macro lens and at least 6 mega pixels of resolution for best results. Shade Guides � There are many different shade guides available to all of us today but the one that remains the standard is the Vita Classic (A-1 thru D-4) from Vident. Most major porcelain manufacturers make their ceramic material keyed to this system. The introduction of the Vita 3D shade guide has generated a great deal of interest but only Vident produces ceramic powders to match this guide. Although it is a great concept, labs that do not use Vita porcelains are forced to devise a formula of their material to match this shade guide which is not always a predictable science. We would recommend using the Classic shade guide whenever possible but understand that sometimes we must deviate to achieve better communication.
