I found the answer at a dental show in Orlando.
It is called Gradia and you can order it from Shari at Nowak Dental Supply. Its made by GC America
Our lab uses Sirona's inLab MCXL for milling, and have had some issues with milling zirconia crowns. We are having problems with marginal chipping during the milling process. When a prep doesn't allow much space for the margin thickness we usually bulk it out a bit, but that creates a lot of extra...
Just wondering what everyone else is using for their zirconia staining... we've been using the Tanaka system, and it doesn't seem to give us very consistent results. Does anyone have any tips for using Tanaka stains, or have a better stain suggestion?
