摘要
Hyflex CM器械是近年开发的一种新型机用镍钛器械,其特点包括:器械由CM丝制成,其Ni的体积比重较传统镍钛合金要低,经过特殊的热处理后具有极佳的柔韧性,其抗折强度也明显提高,使用变形后的器械还可以经过高温灭菌恢复原始形态而得以再生。Hyflex的这些特性可以大大降低根管预备时偏移、台阶或器械分离等并发症的发生。本文就Hyflex CM的特性、物理性能、使用方法等研究进展作一综述。
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.
