DualForce Sectional Matrix System Rings, Premolar, 2/Package

DualForce Sectional Matrix System Rings are engineered with unique dual Nickel Titanium wires and independent interproximal separators to deliver significant, balanced mesial/distal separation force and an excellent matrix-tooth seal. The Nickel Titanium construction resists fatigue for consistent separation force throughout the life of the ring, while the 20° angled placement increases separation force and prevents cusp and rubber dam clamp interference. The non-stick, durable plastic interproximal separators resist composite and adhesive buildup, and the rings are ideal for stacking or butterfly placement techniques.
