MECHANICAL ANALYSIS FOR PROTAPER AND SAF DURING THE ENDODONTIC TREATMENT IN CURVED CANALS
Abstract:
Objective: This study accomplishes a mechanical analysis for ProTaper (F2) and SAF during the biomechanical endodontic treatment for curved canals. Materials and methods: By using 46 X-rays of molars (mesiovestibular canal), we create a virtual root canal, with round cross-section and 2 variables: angle and radius of curvature. Also, 2 models were simulated for the ProTaper and SAF instruments according to their configuration. The interaction between the instrument and the walls of the root canal was made and analyzed with AutoCad 2012 program. Results: We found transformations for all studied cases, proving the efficiency of instruments with better results for SAF. Discussions: SAF proves its efficiency especially for canals with an angle of 600 and a radius of 5 mm. Conclusions: By its special design, SAF is elastic and compressible, determining an evenly applied force to the root canal walls, presenting a safe and effective processing.
