Protaper Next Rotary Files - Dentsply

Like ProTaper Universal, ProTaper Next rotary files feature variable taper performance, but add an off-centered, rectangular cross section for increased file strength. ProTaper Next Features:

• Rectangular cross-section design for greater strength
• Asymmetric Rotary(AR) Motion that further enhances ProTaper canal shaping efficiency
• M-Wire NiTi alloy for increased flexibility and resistance to cyclic fatigue

Next generation technology

Swaggering Effect

ProTaper Next ® ’s innovative off-centred rectangular cross section gives the file a
snake-like “swaggering” movement as it moves through the root canal. The off-centred
cross section and the unique design of the file generate enlarged space for debris hauling.

M-WIRE ®

The M-Wire ® NiTi material improves file flexibility, while still retaining cutting
efficiency. This is achieved through an advanced Dentsply Sirona proprietary thermal treatment process.

Technique Tips

• PROTAPER NEXT TM rotary files (PTN) 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).
• Importantly, radicular access is improved when a ProTaper ® Universal SX file is used, in a brushing manner, to pre-flare the orifice, eliminate internal triangles of dentin, relocate the coronal-most aspect of a canal away from external root concavities, optimally shape canals in shorter roots or produce more shape, as desired.
• Establish a reproducible glide path using small-sized hand files and/or PathFile ® root canal drills.
• Use PROTAPER NEXT TM files in regions of the canal that have a confirmed and reproducible glide path.
• Irrigate, recapitulate and re-irrigate after each rotary file.
• Clean flutes frequently and inspect for signs of distortion or wear.
• The PROTAPER NEXT TM 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 TM 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.
