New flexible CM instruments
To optimize the instrumentation of curved canals in a safe predictable manner, a revolutionary metal has recently been introduced to the market. Controlled Memory files (CM NiTi) are manufactured with a new Nickel-Titanium metal alloy, which has been subjected to a patented thermo-mechanical process. These files demonstrate martensitic properties at room temperature something not observed with conventional NiTi metal. The result is a file with tremendous flexibility and virtually no memory. This remarkable memory-free property allows the instrument to adapt to root canal curvatures, following the root canal anatomy without creating undesirable lateral forces on the outer canal walls that could cause several treatment complications.
