First String™ Retraction Cord is a unique, 100% cotton braided retraction cord that features a tight weave for easy handling. Unlike many cords, non-impregnated First String holds its shape as you manipulate it throughout the placement procedure, maximizing tissue retraction. You'll notice a significant difference when working with First String – it actually stays where you place it! First String gives you superior tactile feel to ensure you do not disrupt the connective tissue fibres, which in turn ensures that you prevent gingival recession and biologic width impingement.
First String strands will not separate and will not fray when cut. And you won’t risk penetrating the cord or seizing strands with your packing instrument. Use the smallest possible retraction cord appropriate for the preparation at hand. First String is the advanced braided retraction cord that stays where you place it.
First String is available in 4 sizes: XS, S, M, and L over 100" of retraction cord in a bottle.
