Features: - Exclusive thermal process: Manufactured using an exclusive thermal process. - All metalurgic transitions as austenite and martensite phases are take place at room temperature, giving many benefits against other NiTi files. - Controlled memory wire: Controlled memory wire allows us to respect the root canal anatomy, avoiding root weakening and the creation of ledges and transportation of canal perforations. - High Resistance: CM wire alloy with special heat treatment gives a very high resistance and flexural fatigue. - Pre-curved: It can be pre-curved and has an extreme efficiency in the most curved canals. - Shape memory: Shape memory permits the file to recover its original shape when sterilized, retrieving all the metallic properties and its metallurgical structure. - Triangular convex section: The instrument section is a triangular convex modified, which facilitates the removal of debris and reduces contact with the canal walls with a very active cutting efficiency. Specifications: - Size: #40. - Taper: 04. - Length: 25 mm.
