Full Cast Crown

Full Cast Crown

For posterior restorative cases when esthetics aren’t critical, no crown functions as well as a classic full-cast restoration. Manufactured from highly biocompatible noble and high noble alloys, cast crowns are won’t chip and fracture like ceramics. Despite their strength, no restoration is as gentle on opposing enamel as full cast crowns, making them an ideal solution for bruxing patients.

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.

  • 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)

All castings are made with a metal alloy, be it non-precious, semi-precious or precious metals. Alloys are classified by their content.
