still have some strength for the preparation. I place a cord on the facial and prep subgingival 0.5-1 mm, then use Cosmedent's pink opaquer in thin layers and then the B-1-A-1 opaquer again from Cosmedent in very thin layers over the pink opaquer until I am satisfi ed with the substrates color. I will then use a thin body shade of Filtek supreme. As far as the material for the crown, I have used Get help on cases at any stage an opaque zirconia framework with porcelain layering. If you do only one central against the natural tooth, becoming satisfi ed with the results has taken me as many as fi ve to six color tries and a remake or two of the crowns before bonding. I have 50 years of experience and of course I have done thousands of PFMs. I would not choose a PFM no matter what. ■ This thread serves as a great example of what Dentaltown does best.
