The COXO CX265-32 needles are precision application accessories for the C-FILL X root canal filling system and were specifically developed for the controlled and consistent delivery of filling material in endodontics. They are designed for dentists and endodontic specialists who require high accuracy in the three-dimensional obturation of root canals. The needles' primary function is the precise delivery of material, even to the apical and difficult-to-access areas of the canal. Their slim geometry and defined outlet control ensure consistent application of warm or malleable filling material. This reduces the risk of voids and improves the seal of the root canal filling. The design is optimized for stable flow control and reproducible results. The needles guarantee a constant material delivery without sudden pressure fluctuations, which is crucial for obturation quality, especially in complex canal geometries. This promotes a homogeneous filling structure throughout the entire canal system. Compatibility with the C-FILL X system ensures a secure connection and reliable application in everyday clinical practice. The precise fit prevents material loss and enables controlled transfer of thermoplastic gutta-percha or other filling materials. The material quality is designed for repeated clinical use. The needles are resistant to thermal stress and common disinfection processes. This ensures consistent performance throughout the entire service life of the 4-piece set. In practical application, the CX265-32 needles facilitate targeted and efficient root canal filling, especially in complex endodontic cases. The combination of precision, stability, and system compatibility supports high-quality treatment. In summary, the COXO CX265-32 application needles offer a reliable, precise, and system-integrated solution for endodontics. They are suitable for professionals who strive for controlled, dense, and reproducible root canal filling.
