  • Dental compositions which can be prepared and worked by the action of oscillations and method for the preparation thereof
    Patent number: 5244933
    Abstract: Curable compositions are described which contain a binder and a high propion 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.
