TwinRing Sectional Matrix System

Adapt to any tooth. The TwinRing’s unique geometry works with any matrix to deliver strong, even tension that separates teeth, seals the matrix without collapse, and prevents composite overflow at the gingival margin—eliminating line angle overhangs. Excellent form memory means the TwinRing retains its original shape for hundreds of uses without warping, so you get consistent, reliable performance every single time.
