The nickel titanium alloy used in NITIFLEX is more flexible than any stainless steel alloy available for endodontic instruments. Moreover, the special core geometry and cross section change progressively throughout the range of sizes, giving NITIFLEX files their unique linear flexibility. With conventional stainless steel instruments, thicker files are less flexible than finer ones. By contrast, in a set of NITIFLEX files the flexibility is practically constant throughout the range.
