Metal Full Cast Crown Economic and Practical Cobalt Chromium

Which dental alloy should be used to make patient's crown?

There are a number of types of alloys that can be used to make all-metal dental crowns. And each one has its own specific composition, and therefore its own unique physical properties, that makes it best suited for certain types of applications.

The patient may be asked to make a decision.

Dentist frequently require input from their patient as to which type should be used (this usually has to do with dental insurance or cost factors).

The following information is aimed at helping you understand the issues associated with making this decision.

Types of dental alloys.

• High noble (precious).

This category represents the "gold standard" of dental alloys, and the one by which all other types are compared.

The composition of a high-noble must include over 60% precious metal (gold, platinum, and/or palladium), of which over 40% is gold.

• Noble (semiprecious).

Alloys in this group must have a composition that's over 25% precious metal (gold, platinum, and/or palladium).

• Non-noble (base).

These alloys contain less than 25% precious metal. A large portion of their content may be nickel, chromium or beryllium. (Some people are allergic to these metals, see above.)
