One of our patients needed her old porcelain fused to metal crown replaced after a root canal. This is an excellent opportunity to jazz up the esthetics, especially after bleaching. How many times have you seen this where they bleached years after a PFM was placed??!!
Picking the right shade is important, but also a bit of characterization goes a long way! In my CEREC Aces class we discuss staining and glazing for a natural appearance. Usually, it takes just a bit of color here and there.
In this case, a little bit of a yellow brown at the root surface is accentuated by placing a mix of white/glaze, or using a higher value glaze. This mixture will add opacity and be a bit higher in value without looking really white. eMax CERAM Fluo is a great glaze to use with it’s slightly whiter appearance. It was used at the cusp tips as well.
