My teeth fillings.

A dental restoration or dental filling is a treatment to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants. They are of two broad types—direct and indirect—and are further classified by location and size. A root canal filling, for example, is a restorative technique used to fill the space where the dental pulp normally resides.


These casting alloys are mostly used for making crowns, bridges and dentures. Titanium, usually commercially pure but sometimes a 90% alloy, is used as the anchor for dental implants as it is biocompatible and can integrate into bone.

Precious metallic alloys

    gold (high purity: 99.7%)
    gold alloys (with high gold content)
    gold-platina alloy
    silver-palladium alloy

Base metallic alloys

    cobalt-chrome alloy
    nickel-chrome alloy

Amalgam

    Silver amalgam or “conventional” dental amalgam ( 65% Silver(min), 29% Tin(max), 6% Copper(max), 2% Zinc(max), 3% Mercury(max) )
    High copper dental amalgam (40% Silver(min), 32% Tin(max), 30% Copper(max), 2% Zinc(max), 3% Mercury (max) )

The composition of alloy powder is controlled by the ISO Standard for dental amalgam alloy in order to control properties, such as corrosion and setting expansion.[4]

Dental Amalgam is widely used because of the ease of fabricating the plastic material into rigid direct fillings, completed in single appointment, with acceptable strength, hardness, corrosion, and toxicity properties. It is more forgiving of preparation and technique than composite resins used for that purpose. High copper dental amalgam is preferred over conventional dental amalgam as it has better corrosion resistance and less susceptible to creep. Amalgam is now mainly used for posterior teeth. Although the mercury in cured amalgam is not available as free mercury, concern of its toxicity has existed since the invention of amalgam as a dental material. It is banned or restricted in Norway, Sweden and Finland.
