Dental Materials, Restorative, Amalgam, Powder
Definition : Amalgam restorative dental materials in powder form designed to be mixed with liquid mercury and used as metallic fillings for in situ restoration of the appearance, structure and/or function of a patient's teeth. These amalgam restorative dental materials consist of high strength powder alloys with irregular particle shape whose main constituents are silver, tin, and copper; they do not contain zinc which therefore minimizes the risk of fracturing the restoration. Amalgam restorative dental materials supplied as powder ensure a long lasting restoration and do not adhere to tooth structure without the aid of cements or techniques which lock in the filling. These amalgam restorative dental materials are strong, resistant to wear, malleable, durable, and can be used in dispensing amalgamators without clogging and agglomeration. Amalgam restorative dental materials are usually placed on the rear molars since their metallic color is not an aesthetic match with natural tooth enamel. They are used in dentists' offices.
