Description:

The X7450421RF EDGEFILE X7 .04 #45 21MM represents a sophisticated rotary endodontic file engineered to deliver exceptional performance, control, and safety while shaping short root canals requiring larger apical preparation. As part of the EDGEFILE X7 product line, this file is manufactured from FireWire™ heat-treated nickel-titanium (NiTi) alloy, renowned for its remarkable flexibility, controlled memory, and great resistance to cyclic fatigue. These metallurgical characteristics greatly diminish the likelihood of file fracture, ensuring the instrument can adeptly follow the natural curvature of the canal, which facilitates safer and more foreseeable shaping. Sporting a #45 tip size, .04 taper, and a working length of 21mm, this file is perfect for anterior teeth and premolars where substantial apical enlargement is essential. The .04 taper guarantees conservative dentin removal while upholding canal integrity, allowing for appropriate irrigation and space for obturation without jeopardizing the tooth’s structure. The file features a non-landed, square cross-sectional configuration, providing aggressive cutting efficiency with minimal contact with the canal walls, thereby lowering torsional stress. This design also encourages smooth and guided file navigation, enabling effective debris removal and reducing the chances of ledging, canal blockage, or transportation. Clinicians enjoy enhanced tactile feedback and smoother navigation, which elevates precision and reduces operator strain. Additionally, the file’s durable cutting capacity and cyclic fatigue resistance contribute to shorter treatment durations, leading to a more comfortable patient experience. Compatible with most rotary endodontic motors, the X7450421RF EDGEFILE X7 integrates effortlessly into various clinical practices. Whether utilized by general dentists or endodontic specialists, this file delivers trustworthy, efficient, and safe shaping outcomes, promoting predictable root canal therapy results and exceptional patient care.
