摘要

Dental restoring materials on the basis of polymerizable compounds which show good mechanical properties and satisfactory polishability after hardening containing at least one new filler consisting preferably of porous silica with a medium particle size from about 5 to about 300 millimicrons and an organo-silicon content from about 5 to about 25%, preferably from 10-12 to 18-20%.
