Gold Alloy

By the Dental Nation clinical team — a licensed dental group practising in the UAE

Gold alloy is strengthened with other metals for indirect restorations and has lower reported annual failure rates than ceramic restorations.

[1][2]

The short answer

Gold alloy is gold strengthened with other metals so it can be used in indirect dental restorations.

What is dental gold alloy?

Why pure gold is changed for dental use
Material pointWhat it means
GoldIt is soft and malleable on its own.[1]
Added metalsCopper, silver, platinum or another hard metal can increase strength.[1]

[1]

Why is gold alloy used?

Gold and platinum-group metals are comparatively stable in the moist environment of the mouth. Gold needs other elements for the strength required in an indirect restoration.

[1]

Where can gold alloy be used?

Metallic materials are used for fixed and removable restorations and appliances. Gold alloys are prepared for indirect restorations rather than placed directly onto tooth structure.

[1]

How does it compare with ceramic?

In the cited trials, conventionally cemented metal restorations had a lower failure rate than adhesively luted ceramic restorations, although the evidence was rated low and all studies had high risk of bias.

[1][2]
Reported annual failure ranges
Restoration typeAnnual failure range
Metal, including gold0% to 2.1%[1][2]
Ceramic2.1% to 5.6%[1][2]

[1][2]

What should a patient know about the alloy?

Gold is not used as pure gold for an indirect restoration. Alloying makes the material stronger, and the additional metals are part of the material placed in the mouth.

[1]

What are the safety and longevity points?

Metal ions released through corrosion can be associated with irritation or allergic responses. Reported sensitivity symptoms include rash, cheilitis, oral lichenoid lesions, stomatitis, and burning, tingling or itching of the oral mucosa or face.

[1][2]

Frequently asked questions

Is pure gold used for a dental restoration?

No. Gold is soft and malleable, so it is mixed with other metals to make a stronger alloy for indirect restorations.

[1]
Can a metal dental restoration trigger sensitivity?

Metal ion release through corrosion has been associated with irritation or allergic responses, including oral or skin symptoms.
