Progress in the Development of New Nickel-titanium Instrument Hyflex CM.

Abstract

Abstract: Hyflex CM, developed in recent years, is a new type of nickel-titanium rotary root canal preparation equipment. Its characteristics include: Hyflex CM is made of a new type of NiTi wire, named the controlled memory wires (CM-wires); it has a lower percent in weight of nickel compared with other traditional NiTi alloy; after a special thermomechanical process, Hyflex CM has excellent flexibility and the ability of cyclic fatigue resistance improves significantly; a sterilization cycle can make the deformed Hyflex CM files regain their original shape and be able to regenerate. These properties may give rise to a reduce risk of transportation, ledging or instrument fracture, and so on. This study discusses research progress on the characteristics, physical properties, and application method of Hyflex CM
