How do you use amalgam?
Just so, what is an amalgam state its use with an example?
amalgam. The definition of an amalgam is a mixture of metals and mercury, which can be man-made or can be naturally occurring. An example of an amalgam is a mixture of silver and mercury which is used as a dental filling.
Beside above, how do you make amalgam fillings? Dental amalgam is a mixture of 50% elemental mercury with a metallic alloy which mainly contains silver and tin. The liquid mercury is mixed with the alloy powder in a 1 to 1 weight ratio. Most dental alloys contain a mixture of silver and tin in a 3 to 1 weight ratio, as well as a lesser portion of copper and zinc.
Hereof, where is amalgam used?
Silver based amalgams have been used as dental fillings for cavities since the 1830's. The initial malleability of the amalgam allows it to be packed tightly into the cavity, where it hardens without either expanding or contracting, forming a hard, permanent filling. Amalgams are also used in gold mining.
Why was amalgam discontinued?
Some scientific studies also reported that patients have been restored to health after having had their amalgam fillings replaced. These mercury-based products were phased out for environmental reasons and precautionary health reasons.
