By combining the principles of cavity design, extension of the cavity into "immune " areas and the development of an alloy with the composition of 68.5% silver, 25.5 

This reaction is called amalgamation. Dental amalgam is the product of the amalgamation between mercury and an alloy containing silver, tin, often copper, and sometimes other elements combined in varying amounts. Dental amalgams are made by mixing one part of liquid mercury with one part of a mixture of other metals: mainly silver, but also tin, some copper and small amounts of zinc. The setting amalgam has the consistency of a paste and is pressed firmly into the prepared tooth cavity to make the filling as strong as possible. no .. amalgam tatoo is not chemically unstable .
