DualForce Sectional Matrix System Rings, Premolar, 2/Pk

DualForce Sectional Matrix System Rings are engineered with unique dual Nickel Titanium wires and independent interproximal separators to provide significant and balanced separation force (mesial/distal) with an excellent matrix/tooth seal. The Nickel Titanium construction renders the rings resistant to fatigue, ensuring consistent separation force throughout their lifespan while requiring less hand strain to open yet delivering stronger separation force on teeth. The 20° angle placement increases separation force and prevents cusp and rubber dam clamp interference, with non-stick, durable plastic interproximal separators that prevent composite and adhesive stick and breakage, making them ideal for stacking or butterfly placement techniques.
