Abstract
Gold powder is inserted in a cavity for the production of fillings in teeth by means of filled gold and this is subsequently hardened mechanically. The moisture sensitivity of this process can be avoided by using a paste made of platelet shaped gold powder with a plastic, organic binder which liquifies at 20.degree. to 45.degree. C. and the mechanical hardening is carried out with ultrasonic.
