Number 5/11 Lime Hirschfeld with Number 6 mesio-distal handle - Hu-Friedy - Delynov

What is the Hirschfeld #5/11 file with #6 handle?

The Hirschfeld #5/11 file, manufactured by Hu-Friedy, is a specialized manual instrument used in periodontology. This device is characterized by a mesial-distal design with a #6 handle, offering a configuration adapted to the requirements of oral surgery. As a mesial-distal periodontal file, it is structured to operate on difficult-to-access dental surfaces. This product is developed by Hu-Friedy Mfg. Co., LLC, a recognized manufacturer in the field of surgical instrumentation, ensuring compliance with professional manufacturing standards for interventions in dental offices or hospital environments.

What are the clinical indications?

This mesial-distal periodontal file is primarily indicated for the mechanical treatment of periodontal diseases. It is used by dental surgeons and periodontists for the removal of highly mineralized subgingival calculus and for root planing. Its use is particularly relevant in furcation areas or deep periodontal pockets where standard curettes may be limited. The instrument allows for the fragmentation of calcified deposits before the final use of a finishing curette, thereby facilitating the reduction of gingival inflammation and promoting epithelial reattachment during non-surgical or surgical periodontal treatment phases.

What are the technical characteristics?

The Hirschfeld #5/11 file from Hu-Friedy features a double working end oriented for mesial and distal faces. The #6 handle is designed to provide a grip adapted to the repetitive movements of periodontal surgery. The working part consists of series of parallel sharp blades, allowing for an effective scraping action on hard surfaces. This device is classified as a Class I instrument according to current regulations. The precision of the fit between the shank and the handle ensures faithful tactile transmission of root irregularities to the practitioner during instrumentation.

What are the contraindications for use?

According to the information provided by the manufacturer Hu-Friedy Mfg. Co., LLC, the use of this instrument is strictly reserved for qualified healthcare professionals. General clinical contraindications include situations where the integrity of the root surface could be compromised by excessive force, or in cases of general medical contraindications to periodontal surgery (e.g., uncontrolled bleeding disorders). It is imperative to refer to the instructions for use and to respect sterilization protocols before any intervention to avoid risks of cross-infection or iatrogenic tissue lesions.

What are the maintenance and durability precautions?

Although this instrument is non-resorbable, its durability depends on rigorous compliance with the cleaning and sterilization cycles recommended by Hu-Friedy. As a Class I medical device, it must be inspected before each use to check the sharpness of the blades and the absence of corrosion. Inappropriate maintenance can alter the cutting capabilities of the mesial-distal periodontal file, making the clinical movement less precise and potentially traumatic for the root cementum. The practitioner must ensure the use of decontamination solutions compatible with metal instrumentation to preserve the mechanical properties of the device over the long term.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Hu-Friedy Mfg. Co., LLC, located at 3232 N. Rockwell St., Chicago, IL 60618, USA. The Hirschfeld #5/11 file is a Class I medical device, compliant with the regulatory requirements applicable to manual surgical instruments. Hu-Friedy is a major player respecting international quality standards for the design of tools intended for dental and periodontal surgery. Professionals must carefully read the instructions before use to ensure compliance with the warnings and safety protocols defined by the manufacturer in order to guarantee a safe and effective clinical practice.
