[Effect of preparation methods on the adaptability of conventional amalgams and amalgams without gamma-2-phase].

Experimental investigations with "Goodfill 700" and "Starfill NG2" amalgams showed, that the adaptability and plasticity depend not only on characteristics of the powder, but are influenced by mixing ratios resp. methods of condensation. Fillings performed from "Starfill NG2", possessing a higher content of powder, but in spherical and smaller particles, have a better adaptability, however a more loose structure at the edges. In case of manual condensation the authors recommend, that the "Dentomat 2" equipment should be used with NG2 at the "0.5", and with G700 at the "-0.5" calibration point.
