Dentapreg fiber reinforcement 

Dentapreg® is a constructive composite, a new class of fiber reinforced composite material suitable for building structures such as dental splints, temporary bridges and large restorations. Adapting cutting-edge technology from the aerospace industry, Dentapreg® combines the best of two worlds: technology and dentistry. The unique properties of Dentapreg® are achieved thanks to perfectly balanced highest-class components and advanced manufacturing technologies. It is composed of glass fibers, which were originally developed for the strength requirements of a space shuttle, and a special blend of  light-curing resin that is compatible with all light-curing composites.
