Product Details
Description:
The ProTaper U Rotary F4 21MM (B) is a premium nickel-titanium finishing file engineered to accurately shape and finish the apical third of the root canal during endodontic procedures. As an essential component of the ProTaper U rotary file series, this file is vital for refining canal shape and ensuring a clean, well-tapered preparation for effective obturation.
Crafted with a progressive taper and sharp cutting edges, the ProTaper U Rotary F4 provides exceptional cutting efficiency and procedural safety. Its nickel-titanium design offers excellent flexibility and resistance to cyclic fatigue, making it ideally suited for use in curved, narrow, or anatomically intricate canals. The 21MM length is especially advantageous for shorter canals and posterior teeth with limited access, improving control and tactile feedback during the treatment process.
The file’s robust, sharp cutting surfaces facilitate effective dentin removal while preserving the canal anatomy and minimizing the potential for procedural issues such as ledging, transportation, or file breakage. Its optimized flute design enhances efficient debris evacuation, keeping a clear canal space and reducing the likelihood of blockages throughout the shaping phase.
When used with an appropriate rotary endodontic motor at the recommended torque and speed settings, the ProTaper U Rotary F4 ensures dependable, consistent shaping outcomes. It integrates seamlessly with other ProTaper U files within a systematic, stepwise preparation protocol, boosting procedural efficiency and minimizing chairside time.
Dentists depend on the ProTaper U Rotary F4 21MM for its blend of precise apical shaping, outstanding flexibility, and reliable performance. It guarantees that canals are adequately prepared for irrigation and obturation, enhancing the overall success and durability of endodontic therapies. This trusted, high-performance instrument plays an important role in delivering safe, efficient, and contemporary root canal treatments.
