Porcelain-Fused-to-Zirconia
If your patient requires extreme esthetics for an anterior cosmetic case, then our porcelain-fused-to-zirconia restorations are an excellent option. We craft these crowns and bridges by layering beautiful porcelain on top of a durable, full-contour zirconia substructure. The porcelain benefits from the clarity of the zirconia, and PFZ crowns offer a warmer appearance than porcelain-fused-to-metal alternatives. They also provide an overall improved appearance compared to PFMs, which may sometimes provide esthetic challenges like discoloration or dark lines along the gingiva.
