STRESS ANALYSIS OF TWO NI-TI ROTARY FILES IN SIMULATED ROOT CANALS USING FINITE ELEMENT METHOD - PART I: FILE ANALYSIS

Ahmed Adel Ibrahim , Salma Hassan El Ashry And Dalia Mokhtar Fayyad,

ABSTRACT
Construction Of An Accurate 3D Model Is Essential To Achieve Realistic Results Using Finite Element Analysis. In This Study The Mechanical Behavior Of Two Metallurgically Different Files Has Been Examined In Precise Root Models With Different Radii. Results Revealed That ProTaper NEXT Showed Lower Stress Values Than HyFlex CM In Both Radii. Therefore, Geometry Plays An Important Role In The Amount Of Stress Accumulation Within Different Files During Performance.
