Abstract

A pasty dental material is disclosed which hardens to a high gloss polishable mass in the presence of an initiator. The mass is formed of a polymerizable bonding agent combined with an organosiloxane filler which contains units of the formula I ##STR1## and which has been subjected to an after treatment which is a condensation in an autoclave for a period of time of 1 hour to 5 days at a temperature of 60.degree. C. to 250.degree. C. under a pressure which is the sum of the partial pressures at the given temperature.
