The safety of the reciprocation movement reaching a higher level of efficiency M-One Gold reciprocating files use the asymmetric reciprocation left cutting motion, allowing the efficacious shaping of even severely curved root canals with fewer files. The proprietary heat treatment used in the M-One Gold manufacturing process gives more flexibility and 3 times increased cyclic fatigue resistance (comparing with a non-heat treated NiTi wire) letting a smooth, safe, and efficient instrumentation.
