One-Fil is a calcium silicate-based bioceramic root canal sealer designed to support stable root canal obturation through excellent sealing performance. With its superior flowability and wettability, it can be effectively applied to complex root canal anatomies and microscopic spaces, while being optimized for the Single Cone Technique to support a simpler and more efficient clinical procedure. In addition, One-Fil promotes biomineralization at the interface with the root canal wall, helping to achieve stable canal sealing, and its high biocompatibility allows for reliable use in various clinical situations. It can be widely applied in a range of endodontic procedures, including retreatment cases. Furthermore, the SAVE TIP system minimizes residual material inside the tip, reducing material waste and improving overall efficiency. Its user-friendly delivery system also helps provide a more hygienic and stable treatment environment.
