-
Restorative dental materials consisting of metal alloys designed to be combined with mercury (i.e., to obtain dental amalgam) for in situ restoration of the appearance, structure and/or function of a patient\'s teeth. These alloys are the product of the fusion of several metals (e.g., silver, tin, zinc, and copper) to form an alloy that is appropriate for mixing with mercury; dental alloys are used in dentists\' offices when dental amalgam is not available or in-situ mixing is desirable for other reasons.
