Features: - Easy: Plex RC-ONE is designed to completely prepare a root canal with one single reciprocating instrument in most cases, being easy to learn and teach, with less probability of procedural errors, the selection of the Plex RC-One file depends on the clinical case difficulty. - Safe: A unique design with two different cross-section profiles, a reciprocating movement with balanced rotation angles, and a very flexible alloy generates maximum resistance to cyclic fatigue and reduces the risk of instrument fracture, optimal for the management of canals with severe curvatures and complex anatomies. - Efficient and Effective: Preparation time is reduced due to the instrument design with a constant taper, two cross-section profiles and a great cutting capacity, which enhances preparation and irrigation, modified convex triangular cross-section of the tip provide instrument stability, and the S-shaped cross-section of the file body helps preserving the original shape of the canal and it has a variable helical angle that allows efficient debris removal coronally, an inactive pilot tip to maintain the original shape of the canal, and a short transition angle to provide efficient cutting. - Flexible: Plex RC-ONE is made of a modified nickel-titanium CM wire alloy, and it is manufactured using an exclusive thermal process at room temperature that gives it great flexibility, which helps preserve the original shape of the canal due to memory control, great cutting capacity, and high resistance to cyclic fatigue. Specifications: - Speed: 300-500 RPM. - Torque: 2-3.0 N.Cm. - Size: #25. - Taper: 04.
