mb+ MyEndo Gold Flex Rotary Files – 21mm Assorted is a comprehensive rotary file set designed to deliver flexibility, efficiency, and control during root canal preparation. Manufactured using advanced gold thermal heat treatment, these files offer superior flexibility and enhanced resistance to cyclic fatigue, making them suitable for a wide range of canal anatomies, from narrow and curved to wider canals.The files feature a triangular cross-section with sharp cutting edges, ensuring efficient dentin removal, smooth canal shaping, and reduced treatment time. The non-cutting safety tip helps minimize the risk of apical transportation, allowing safe and predictable instrumentation.With a simplified usage protocol that typically requires only 2–3 files per case, the 21mm assorted pack provides versatility and convenience for daily clinical use while minimizing debris extrusion. This assortment is ideal for clinicians seeking a reliable, all-in-one solution for efficient and effective endodontic procedures.FeaturesGold Thermal Treatment for Enhanced Cutting EfficiencyEnhances flexibility and cutting performance while improving resistance to cyclic fatigue.Triangular Cross-Section for Optimized CuttingSharp cutting edges improve shaping efficiency and reduce instrumentation time.Non-Cutting Safety TipMinimizes apical transportation and protects canal anatomy.Specialized Heat Treatment for Flexibility and DurabilityEnsures consistent performance in curved and complex canals.Stable Flutes for Stress ResistanceMaintains structural integrity under high-stress clinical conditions.Efficient Usage ProtocolSimplified sequence requiring only 2–3 files in most cases.Improved Navigation in Complex AnatomySuperior flexibility allows smooth navigation across varying canal anatomies.Minimized Debris ExtrusionEfficient design helps reduce debris extrusion for cleaner canal preparation.
