What is the meaning of Gold Alloy?
Gold Alloy is widely used term in Dental Materials.
Gold alloy in dental materials refers to a mixture of gold with one or more other metals. It is commonly used in dentistry to fabricate dental restorations such as crowns, bridges, inlays, and onlays. Gold alloys offer several advantages in dental applications, including excellent biocompatibility, high resistance to corrosion and tarnish, and durability.
The composition of gold alloys for dental use may vary, but they typically contain a high percentage of gold (usually around 75% or higher) combined with small amounts of other metals such as silver, copper, palladium, or platinum. These additional metals are added to improve the mechanical properties of the alloy, including strength, hardness, and flexibility.
The specific characteristics of a gold alloy can be tailored to suit the specific requirements of a dental restoration. For instance, high noble gold alloys contain a high percentage of precious metals like gold, platinum, and palladium, making them more aesthetically pleasing and resistant to tarnish. In contrast, noble or base metal alloys contain a smaller percentage of precious metals, making them more cost-effective and suitable for applications where aesthetics are less important.
Overall, gold alloys in dental materials provide a reliable and long-lasting solution for dental restorations due to their excellent biocompatibility, resistance to corrosion, and favorable mechanical properties.
