The Dentsply Protaper Next Files are rotary endodontic files made of nickel titanium, used in biomechanical preparation of the root canal system. This Pro Taper Next file system provides various shaping advantages through a variable tapered design on a given file, M-Wire technology and a unique offset mass of rotation. It is a versatile and flexible system capable of handling a majority of root canal treatments, including the complex cases. ProTaper Next Files has been the gold standard in endodontics for many years and has been an effective solution for practitioners. The ProTaper Next file system utilizes increasing and decreasing percentage tapered design on a single file. This aids in minimizing the contact between the file and dentin, which increases the efficiency while decreasing the dangerous taper lock and the screw effect. ProTaper NEXT Dentsply files have swaggering movement of the file and utilize the innovative M-Wire technology for strengthening NiTi.
