The ProTaper Next X4 rotary file has a tip size 040 and 6% taper, and is used after the ProTaper Next X3 file if the apical foramen is larger than a size 030.
The ProTaper Next rotary system is a convergence of the most proven and successful generational designs from the past, coupled with the most recent advances in technology. Together, the M-Wire NiTi material and the patented, off-centered rectangular cross-section give rise to numerous benefits. Matching paper points, gutta percha points and GuttaCore obturators complete this innovative system.
- Improved file flexibility
- Decreased risk of file separation
- A shorter clinical sequence versus ProTaper Universal
