TG6 - Gold standard rotary file. TG6 provides more than twice the resistance to cyclic fatigue as MTF and that's an important advantage, because cyclic fatigue is the leading cause of file separation. TG6 features the same simplicity and smoothly tapered shapes you know and trust from MTF. Developed with proprietary advanced metallurgy. TG6 rotary files offer greater flexibility for MTF performance that's better than ever. The TG6 technology includes a series of "Shaping"and "Finishing"files that create the predictablet shapes,and a system proven and trusted by clinicians throughout the world.
