The Quad Wedge utilizes a revolutionary split-tip design. Split tip easily adapts bands to both cervical margins! Gently slides alongside papilla and seals deeper for a more natural emergence profile even with mismatched depths. Seal those concavities! Quad Wedges include the highly specialized anatomical purple wedge designed for an improved seal when presented with a root concavity. Prevents flash and contamination. Improves matrix adaptation.
