Advantages of Gold Based Full Cast Restorations

Gold has been used for dental restorations for as long as records have been kept. It can be called the alloy of choice for the mouth.

Its key advantages are:
- Corrosion resistant
- Non-reactive in the mouth
- Malleable for superb marginal adaptation
- Soft on the opposing dentition

Among the most important concerns for using any foreign material in the mouth is the concern for the constant and ever changing environment. With both saliva and acidities from the body and food, dental restorative materials are subject to extremely harsh conditions. That, together with chewing and grinding forces, creates challenges for many materials. Gold, as a corrosion resistant and a non-reactive material, adapts very well to these harsh conditions. Additionally, with its natural softness and malleability, gold allows for almost perfect margin adaptation and does not wear away at the opposing dentition.
