Full Cast

Full Cast thumbnail

Full cast crowns are a foundational restoration in the dental industry. They still retain a popular prescription choice for clinicians due to their dependability in both strength and biocompatibility. The technicians at Apex craft our full cast crowns out of a variety of high-quality alloys, including noble white, noble yellow, high noble yellow, and yellow non-precious. Our laboratory has fully embraced digital innovation, and that choice has not missed full cast crowns. We use the latest in CAD/CAM equipment to fabricate our full cast crowns to ensure they offer ideal anatomical contours and fit.

Benefits:

  • Consistent Fit
  • Superior Precision
  • Gentle on Opposing Dentition
  • Easy to Use

Indications

Full-cast gold crowns are indicated for crowns, veneers, inlays, onlays, and bridges.

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 tin plated if precious metal is used)
  • Glass ionomer cement (GC Fuji, GC America)
  • Zinc Phosphate Polycarboxylate Resin Ionomer cement (RelyX, 3M ESPE)

Tech Notes

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

  • Base – contents include non-precious, Chrome Cobalt or Titanium
  • Noble – consists of 25 percent precious alloy
  • High Noble – consists of 60 percent precious metal with at least 40 percent being gold

Alloy type refers to the hardness and/or softness of the material.

  • Type I – Extra soft
  • Type II – Soft
  • Type III– Hard
  • Type IV – Extra Hard (Rigid)
  • Non-Precious, Noble 20, White High Noble – Type IV – Very hard and rigid. These crowns are more difficult to adjust and re-polish than alloys with a high gold content.
  • Full Cast 40 – Type III – Yellow high noble alloy. Brand name currently used is Argenco 40 HN.
  • Full Cast 52 HN – Type III – Yellow high noble alloy. Brand name currently used is Argenco 52.
  • Full Cast 75- Type III – Yellow high noble and is an upgrade from full cast 52. The gold is slightly more yellow in color. Brand name currently used Argenco 75.
