Abstract

Polymerizable and hydrolysable oxetane silanes and in particular silicic acid condensates which can be prepared therefrom are described, which exhibit only a low volume shrinkage on polymerization and produce polymers with high mechanical strength and therefore can be used above all as dental material or constituent thereof.
