Abstract

The effect of γ1 and γ2 on the creep deformation of dental amalgams has been investigated. It has been shown that the creep of a conventional amalgam is not dependent on γ1 as was previously reported. Rather it is strongly influenced by γ2 and its volume fraction. It has been speculated that Sn‐rich grain boundaries also enhance creep by facilitating grain boundary sliding. The reported correlation between creep and marginal fracture has been explained in terms of this dependence of creep on corrosionprone Sn‐rich microstructural constituents of amalgams.
