Abstract:
1. Dental composition containing (a) 10 to 60 wt.-% of at least one monomer and/or oligomer which is polymerizable by ring-opening metathesis polymerization, (b) 5 to 90 wt.-% of at least one particulate dental macro-filler or dental mini-filler having an average particle size of from 0.01 to 5 μm containing quartz, glass ceramic or glass powder, or at least one particulate dental microfine filler having an average particle size of from 0.005 to 0.5 μm containing pyrogenic silicic acid, or precipitated silicic acid, or a mixed oxide of at least one of SiO (c) 0.01 to 0.08 wt.-% of at least one initiator for ring-opening metathesis polymerization, characterized in that the initiator is chemically or physically bound to the filler and the composition is solvent-free, substantially colorless or tooth-colored and has properties suitable for use in a dental patient's mouth.
