Filter retraction spatula number 113NS handle number 41 angled - Hu-Friedy - Delynov

What is the Hu-Friedy #113NS retraction cord packer?

The #113NS retraction cord packer is a specialized manual instrument developed by the manufacturer Hu-Friedy Mfg. Co., LLC. This device consists of a thin working part and a #41 handle. Its structure is specifically studied for the manipulation of gingival retraction cords. As an instrument in the INSTRU category, it meets the needs of practitioners looking for a reliable tool for peri-dental soft tissue management. Its angled design allows for an ergonomic approach to different sectors of the oral cavity, ensuring controlled handling during critical stages of restorative or prosthetic dentistry.

What are the clinical indications for this instrument?

This angled retraction packer is indicated for the placement of retraction cord in the gingival sulcus. Its use is essential during fixed impression procedures to clear the cervical margins of preparations. It is also used in operative dentistry to isolate the working field and protect the marginal gingiva during the placement of direct restorations. The instrument allows for the application of gentle and precise pressure to insert the cord without damaging the epithelial attachment, thus ensuring effective and temporary tissue retraction necessary for the accuracy of prosthetic work.

What are the technical characteristics of the #113NS packer?

The #113NS retraction cord packer is distinguished by its #41 handle and its angled configuration. The angulation of the working part is optimized to follow the dental anatomy and access hard-to-reach areas, such as the distal faces of molars. Manufactured by Hu-Friedy, this instrument benefits from the brand's technical expertise in manual instrumentation. The thinness of the active tip allows for the insertion of cords of different diameters into the gingival sulcus with great precision. Its monobloc structure ensures direct transmission of the force applied by the practitioner, facilitating homogeneous packing of the cord around the entire circumference of the tooth.

What are the contraindications for the use of this device?

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 gingival tissues show severe inflammation or non-stabilized periodontal pathology that could be aggravated by mechanical retraction. The instrument should not be used if the integrity of the working part is compromised. The practitioner must read the instructions for use carefully before any intervention to become aware of all the warnings and safety protocols specific to the device.

What are the precautions for use and maintenance?

As a non-resorbable Class I instrument, the angled retraction cord packer requires a rigorous cleaning, disinfection, and sterilization protocol between each patient, in accordance with Hu-Friedy instructions. The practitioner must ensure not to exert excessive pressure during cord insertion to avoid any trauma to the deep periodontium. Regular visual examination of the angled tip is recommended to detect any sign of wear or deformation that could impair the precision of the clinical gesture. Compliance with the sterilization cycles recommended by the manufacturer guarantees the longevity and safety of use of the instrument in the dental office.
