Description
Flexer Hybrid 15–40 4% 21mm is a premium nickel-titanium (NiTi) rotary endodontic file system designed for smooth, controlled, and efficient canal shaping. The hybrid design combines superior flexibility with enhanced cutting performance, making it ideal for all types of root canal anatomies. The 4% taper ensures conservative dentin removal while maintaining canal integrity. With a 21mm length, it offers excellent access and precision in both anterior and posterior teeth.
DIRECTIONS TO USE
Establish a glide path using hand files up to size #15.
Begin shaping with Flexer Hybrid 15 (4%), followed by progressive sizes (20, 25, 30, 35, 40).
Operate at a speed of 300–500 rpm and torque of 2–3 Ncm.
Use a gentle pecking motion — avoid forcing the file apically.
Maintain continuous irrigation (sodium hypochlorite) during instrumentation.
Clean and inspect the file after every use; discard after single use to prevent breakage.
