Clinician's ChoiceĀ® DualForceā„¢ Active-Wedges actively engage the matrix band and adjacent tooth. Active-Wedges are designed to easily glide into position with a collapsing tip that re-opens once fully placed. The ideal Active-Wedge contour and strong internal spine place significant force on the matrix band to seal margins to eliminate overhangs and reduce composite flash ā€“ translating to less finishing time. Other features and benefits include:

  • Ideal contour to provide matrix/wedge/tooth seal to minimize flash and eliminate overhangs
  • Collapsing tip for easy placement, rebounds when fully seated ā€“ preventing back-out
  • Provides 2lbs of separation force
  • Strong internal spine creates tooth separation, increases seal at proximal box
  • Notched handle to match cotton pliers
  • Available in 5 ISO colour-coded sizes, including #5 ā€œDeep Sealā€ Wedge

  4. Once seated, the DualForce Sectional Matrix System provides a complete gingival seal with a tight vertical seal of the matrix band along with a strong and stable separation force, resulting in less chance of composite flash.
