Dentsply Protaper Next Rotary Files

– The Dentsply Protaper Next is the newest innovation to the ProTaper Universal system, which has been the gold standard in endodontics for many years
– These are rotary endodontic files made of nickel-titanium, used in biomechanical preparation of the root canal system
– It is an efficient solution for endo practitioners seeking a versatile, flexible system that will handle the vast majority of root canal treatments, even the most complex cases
– The key evolutions of ProTaper NEXT are the swaggering movement of the file and the utilisation of our proprietary strengthened NiTi, M-Wire technology
– These files produce a unique asymmetrical rotary motion
– The ProTaper Next file system utilizes an increasing and decreasing percentage tapered design on a single file. This aids in minimizing the contact between the file and dentin, which increases efficiency while decreasing the dangerous taper lock and the screw effect
– Off-Center rectangular code adds greater strength to the file as it tracks down the canal
– Protaper next rotary files should be used in a torque control, electric motor at a speed of 300 RPM with light apical pressure
– For optimal usage, torque control devices are recommended at 200 gcm (adjustable up to 520 gcm according to practitioner experience)
– Use Protaper Next files in regions of the canal that have a confirmed and reproducible glide path
– The Protaper Next instruments are recommended to be used with a brushing motion, away from external root concavities, to facilitate flute unloading and apical file progression
– Use the Protaper Next files to passively follow the canal until the working length is achieved. The sequence is always the same regardless of the length, diameter or curvature of the canal
– Indication:
– Used in the biomechanical preparation of the root canal during endodontic therapy
– Directions to Use:
– While using NaOCl, follow the established glide path with ProTaper Next X1 file till working length
– Use ProTaper Next X2 in the same manner
– Gauge the size of the foramen using a #25 size hand file
– If the file binds at length, it indicates that the canal is shaped and ready for disinfection
– If the file is loose at complete working length, continue shaping with X3 file and if necessary X4 and X5 files, gauging after each instrument change with #30, #40 or #50 hand files respectively
