Control of the esthetic outcome is one of the huge benefits for CAD/CAM dentistry. I hate to admit that I inserted the Porcelain-fused-to-metal crown many years ago. It was one of those times, where it didn’t “really matter” because it is so difficult to match PFM’s in a situation like this. Years later after incorporating CEREC into our office, it “does matter.” When you have the control for esthetics, it only makes sense to attempt the closest shade possible. When you have the final ceramics chairside, this is MUCH easier to do.
I asked the patient if we could remake the crown for no fee. I promised that I could make it look better. She obliged.
Blending Emax CAD HT is fairly simple and if the thickness of the margins fade just a bit, they can melt into the tooth after bonding. A little red chroma in the body, and this was ready to go. James Klim has an excellent radio cast on this very subject here.
CEREC users get spoiled with their ability to control so many things of the clinical outcome, especially the esthetic control.
