Cast gold restorations have overall characteristics unavailable in any other restorative procedure for inlays and onlays, including low restoration wear; low wear of opposing teeth; lack of breakage; burnishability-malleability; and proven long-term service. Bonding cast gold restorations with resin cement improves their characteristics even more. However, they are not tooth-colored, which eliminates them from consideration for many patients. Although tooth-colored inlays and onlays, both ceramic and filled polymer, are increasing in use, and their serviceability is acceptable at a moderate level, cast gold restorations remain the standard of care for long-term indirect restorative service.
