摘要/Abstract

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。

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
