DENTSPLY Tulsa Dental Specialties’ ProTaper NEXT™ boasts the same variable taper design found in the original ProTaper that clinicians have turned to for more than a decade, but refined to improve performance. ProTaper NEXT features the patented M-Wire® NiTi alloy for increased flexibility and resistance to cyclic fatigue, a rectangular cross-section for greater strength, and a unique Asymmetric Rotary (AR) Motion. ProTaper NEXT also uses the same trusted rotary action as the original ProTaper, however there is a difference in how the file moves down the canal. The off-center rectangular cross section of ProTaper NEXT differs from the center of mass. Only two points of the cross section touch the canal wall at a time, reducing the torsional stress on the file. The result is a fully-tapered and predictable shape achieved with greater procedural efficiency. The single-use and pre-sterilized ProTaper NEXT files also feature shorter handles (11 mm) and are available in 21, 25 and 31 mm lengths. Four sizes of color coded and precision-matched absorbent points, gutta-percha points, and obturators fit all ProTaper NEXT prepared canals.
