Developed by dentist Dennis Brown, DDS, Greater Curve makes U.S.-made dental matrix bands and soft-sided retainers built around its distinctive funnel-shaped Tofflemire system. The curved bands are designed to reach adjacent teeth and form tight, deep contacts without routine wedging, including in wide embrasures and difficult anterior restorations. The company also shares detailed clinical guidance showing how its system is used in challenging composite and subgingival restorations.
