Zusammenfassung:The purpose of this study was to investigate the influence of relevant microstructural and compositional factors on the creep of 12 representative dental amalgams by means of stepwise multiple linear regression. The independent variables accepted by the regression were volume percent of the η'(Cu6Sn5) phase, grain size of the γ1 (Ag2Hg3) phase, volume percent of the y (Ag3Sn) plus E (Cu3Sn) phases, number of very small η' crystals (< 1.5μm) per mm, and weight percent of Hg. The results of this regression showed an adjusted R2 of 0.949, significant at p = 0.002.
