Abstract

Dental materials containing monomers and/or prepolymers can be subjected to a polymer-forming reaction. The dental materials comprise at least one initiating system and optionally comprise fillers, colorants, flow modifiers, stabilizers, ion-releasing substances as well as compounds which increase X-ray capacity or other modifiers. The dental materials are characterized in that the initiating system is proportioned such that the dental materials are sufficiently capable of flowing for at least 10 seconds after exposure to oxygen, whereupon they subsequently harden into a solid material.
