Heat-treated to increase file flexibility, V-Taper™ 2H NiTi Rotary File system insures root canal navigation without ledging, transportation or zipping, even in the most curved canals. Standard NiTi files continually try to revert to their original straight shape. The proprietary processing of V-Taper2H files reduces shape memory, allowing them to follow the natural contours of the canal while reducing the tendency to straighten out.
