HyFlex EDM 单支锉是本研究中拥有最佳根管定心能力的HyFlex CM的增强型产品,证明了当使用CM-Wire技术时,即使仅用一支锉,也可以很好的维持S形根管的中心,这与使用类似于HyFlex CM的多支锉系统预备的根管效果相当。 ProTaper Next锉的偏心横截面确保了其可以更好地顺应根管的走向,可变的锥度、较短的序列和较高的切...

Introduction: The purpose of this study was to evaluate the effect of a low amount of torsional preloading on the fatigue life and different degrees of cyclic fatigue on torsional failure of HyFlex EDM (EDM; Coltene-Whaledent, Allstetten, Switzerland) and HyFlex CM (CM; Coltene-Whaledent) ...
RESULTS: XRD analysis on HyFlex EDM revealed the presence of martensite and rhombohedral R-phase, while a mixture of martensite and austenite structure was identified in HyFlex CM. DSC analysis also disclosed higher austenite finish (Af) temperatures for EDM instruments. Significant differences in ...
The aim of the present study was to compare the effect of exposure to sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) on the surface topography and roughness of HyFlex controlled memory (CM) and HyFlex electrical discharge machining (EDM) using atomic force microscopy (AFM)....
