The Strata-G system is the next step in sectional matrix versatility, adaptability, and consistency of excellent restorations. Built to handle wide preps, deeper margins, and primary teeth with minimal flash and finishing time. "Strata-G™ rings feature Nitinol drawn-wire nickel titanium which is aligned at the molecular level for superior performance yet requires less effort to open. Marginal ridge enhancements built into the matrix bands AND rings help provide that finishing flair! The Strata-G™ rings, bands and wedges combine for a 270° Seal™ for ultimate flash control. The rings won’t spring off the tooth, and the amazing Wide Preparation ring makes tough wide preps no problem. The inverted V shape sits lower and seals deeper interproximally while flexible side walls and Soft-Face™ TPE over-mold allow Strata-G™ Wedges to easily adapt to concavities and irregularities.
