DENTAL COMPOSITIONS WHICH CAN BE PREPARED AND WORKED BY THE ACTION OF OSCILLATIONS AND METHODS FOR THE PREPARATION THEREOF

摘要

Curable compositions are described which contain a binder and a high proportion of fillers having a mean grain size of <50 mu m. The filler proportion of the curable compositions is so high that they cannot be used for the intended purpose because of their high viscosity However, they can be liquefied by exposure to oscillation in the frequency range of 20 Hz to 20 MHz with an amplitude of 1 mu m to 5 mm so that they are workable and can be employed for the intended purpose.
