HyFlex CM Controlled Memory NiTi Rotary File, Size 40, .06 Taper, 31mm, 6/Pk

HyFlex CM NiTi rotary files feature controlled-memory technology, providing exceptional flexibility without the shape memory of conventional NiTi files. This allows the file to closely follow the canal anatomy, reducing the risk of ledging, transportation, or perforation. The files respond to excessive resistance by straightening spirals, which avoids binding and increases fracture resistance; their form can be restored via heat treatment (autoclaving or glass bead sterilization).
