随着现代根管治疗概念的普及和新材料新设备的引进,根管治疗的方法和所使用的器械有了很大的改进。其中镍钛根管预备器械的大量应用就是其中之一。机用镍钛根管预备器械由于其材质具有高弹性、抗折性和高效切割性能,使根管预备的效率和质量显著提高。然而随着其临床使用的日益普遍,器械折断时有发生,严重困扰着临床医
With the popularity of modern root canal therapy concepts and the introduction of new materials and new equipment, there has been a significant improvement in the methods of root canal therapy and the instruments used. One of the many applications of nickel-titanium root canal preparation equipment is one of them. Machine with a nickel-titanium root canal preparation equipment because of its material with high elasticity, bending and cutting performance, so that the efficiency and quality of the root canal preparation significantly improved. However, with the increasingly widespread use of its clinical equipment, equipment breaks occur from time to time, seriously harassing clinicians
