Coltene HyFlex NiTi Rotary Files 4% Taper 25mm – Dental Root Canal Endodontic Instruments

HyFlex™ Controlled Memory NiTi Files

HyFlex™ Controlled Memory NiTi Files are created using a unique process that controls the material's memory. This innovation improves performance during use. The files are compatible with crown-down, step-back, or the recommended single length technique. This versatility allows dental professionals to select the ideal method for each clinical case.

Exceptional Resistance to Separation

300% more resistance to separation makes the HyFlex CM files stand out in their category. They demonstrate up to 300% higher resistance to cyclical fatigue compared to traditional NiTi files. This increased durability greatly reduces incidences of file separation during endodontic treatment, helping clinicians perform safer procedures.

Superior Canal Tracking with No Rebound

HyFlex Controlled Memory NiTi files use a special manufacturing process to control the material’s memory. The files are extremely flexible without the shape memory effect seen in other NiTi files. This allows them to closely follow the natural canal anatomy, lowering risks such as ledging, transportation, or perforation. The combination of no rebound and extreme flexibility ensures superior canal tracking during use.

Multi-Use Capability Through Shape Regeneration

The shape and strength of files with straightened spirals can be restored via autoclaving. This allows for multiple uses of the same file, lowering costs and environmental impact. However, files that do not return to their original shape after sterilization should be discarded to maintain safety and effectiveness.

Product Features

• Constructed from regenerative Titanium Nickel.
• Pre-sterilized for immediate clinical use.
• Exhibit significantly higher resistance to cyclic fatigue than conventional NiTi files.
• Low risk of file fracture during procedures.
• Designed to follow canal anatomy to reduce risks of steps, displacements, or perforations.
• Highly flexible and break-resistant for durability.
• Long life expectancy, thanks to the integrated controlled shape memory that allows shape recovery after heat treatment in the autoclave.

Directions for Use

Inspection

• Before use, carefully inspect each file for any visible defects or damage.
• Check the expiration date and ensure the files are within the valid period.

Preparation

• Gather all required equipment, such as handpieces and irrigation solutions.
• Ensure the treatment area is properly isolated and fully prepared for the procedure.

File Selection

• Select the appropriate file size based on the anatomy of the canal. Use the size chart for guidance.
• Consider the taper and length to meet the specific requirements of your procedure.

Sterilization

• Confirm that the files are sterilized properly before use.
• Follow recommended autoclave sterilization protocols to maintain file safety.

Techniques

• HyFlex CM files can be employed using crown-down, step-back, or a single length technique.
• Choose the technique that suits the clinical situation and treatment goals.

Canal Preparation

• Start canal preparation using a gentle, controlled in-and-out motion.
• Maintain adequate irrigation during the procedure to remove debris effectively.

Controlled Memory Advantage

• Utilize the controlled memory feature to closely follow the canal’s complex anatomy.
• Benefit from the file's extreme flexibility without the rebound effect found in other files.

Resistance to Separation

• Take advantage of the high cyclic fatigue resistance to minimize file separation risk.
• Monitor the file condition during treatment closely, replacing any deformed or damaged file.

Sterilization After Use

• Files with straightened spirals can be restored by autoclaving for safe reuse.
• Discard any files that do not regain their original shape after sterilization adequately.

Post-Procedure Care

• Follow standard post-procedure care protocols to ensure patient safety and file maintenance.
• Clean and sterilize instruments correctly for reuse or dispose of them following regulations.
