Full Cast Crowns

A perfect prosthetic option for anterior cases when esthetic concerns aren’t a factor in material choices, our noble and high-noble full cast crowns and bridges are the most biocompatible solution available. The strength of cast metal ensures they’re durable enough for a lifetime of use, while being the most forgiving restoration on opposing dentition available.

Preparation

Inlays and onlays can also be fabricated as a full-cast restoration.

Feather-edge margin preparations are indicated for full-cast restorations, but any margin preparation may be used.

Cementation

  • Panavia 21 (Must be tinplated if precious metal is used)
  • Glass ionomer cement (GC Fuji, GC America)
  • Zinc Phosphate Polycarboxylate Resin Ionomer cement (RelyX, 3M ESPE)
