Accolade OP Mask is a light-cure paintable composite used as a first increment for masking tooth discolorations and metals. Accolade OP Mask is built on Accolade chemistry and requires no mixing. It can be used between a bonded tooth surface and an overlaid resin-based restorative or porcelain veneer to mask unwanted color, for example tetracycline stain. It can be used on prepared metals to mask the metal color for repair of porcelain fused to metal crowns.
