NRT FILES pack consists of SSt files/Orifice Openers and NiTi files. MANI NRT Orifice Openers(.14, .12, .10 and .08 tapers) are used to safely open the canal orifice to facilitate complete canal preparation. MANI NRT NiTi Files(.06 and .04 tapers) are used to prepare the mid-root and apical portions of the canal space, and creating a continuous tapered preparation, following the natural canal path. MANI NRT Files(NiTi) uniquely combine two important characteristics of the nickel-titanium alloy - shape-memory effect and super-elasticity-resulting in better durability and less breakage than other NiTi Files. MANI’s patented treatment of the alloy provides superior strength in the apical portion of the file resulting in increased resistance to fracture.
