DUAL-FORCE™ Sectional Matrix System

CLINICIAN'S CHOICE Dental Products, Inc.

Benefits
Dual NiTi rings produce up to 37% more separating force while greatly reducing the hand strain required to expand the ring. The use of concentric NiTi wires ensures that the stress of expanding the ring is evenly distributed along the wires themselves, eliminating both the possibility of fracture and the need to retension. Independent articulated separating prongs provide equal and opposite separation force to the embrasure space. The angle and design of these interproximal separators serve to drive the prongs deeper into the embrasure space, adapting to the cusps for enhanced stability, eliminating the chance of “pop-off,” and helping to seal the vertical margin of the preparation to minimize composite flash. 

Features
DUAL-FORCE's Active-Wedges™ are contoured and incorporate a hollowed tip that collapses for easy insertion and then rebounds to lock the wedge into place and fully seal the matrix band against the gingival margin. All five sizes of Active-Wedges contain a strong internal spine, enabling them to exert 2 lbs of separation force. Deep gingival margins that approach furcations are always a challenge to seal and make it difficult to limit the amount of composite overhang.
