BISFIL 2B is a self-cured composite that alleviates concerns about fully polymerizing in posterior restorations. The system is specifically designed for use as the base increment in a Class I or II restoration. BISFIL 2B is available in a Universal and A3/A3.5 shade. BISFIL 2B is both radiopaque and rapid setting. Rapid setting eliminates time spent with incremental placement of light-cured materials.
