title: [Gamma-2-free amalgams: effect of technic (trituration) on physical properties].
abstract: The goal of investigation was to find the physical data, viz. changes of volume, pressure resistance after 1 and 24 hours, creep value of gamma-2-free amalgams (dispersion type), to compare the values to each other and to those of conventional amalgams. On the whole, gamma-2-free amalgams are superior to the conventional products. The pressure resistance after 1 hour is considerably higher, and the creep values are significantly lower. Furthermore, it could be proven that a mixing unit of high RPM was able to improve the quality still more. The best results were found with Amalcap non-gamma 2 and Dispersalloy evenly, both premeasured in capsules and triturated in the Silamat unit. Similar data were found with Dispersalloy tablets, mixed in the Diomat II unit at 3000 RPM. Before clinical long-range examinations can be obtained, judgment of quality cannot be passed.
