ABSTRACT:
The invention describes a material for making temporary crowns and bridges that comprises two pastes and can be mixed in a static mixer/application in one cycle without the incorporation of bubbles, and can be easily pressed out. The polymers produced from this are aesthetically pleasing and remarkably break-resistant. Their polymerization-related shrinkage proves to be extremely low. Their radiopaqueness meets clinical requirements.
