MASAS DENTALES QUE PUEDEN FABRICARSE Y TRANSFORMARSE MEDIANTE LA ACCION DE VIBRACIONES Y PROCEDIMIENTO PARA SU FABRICACION.

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.
