Filter retraction spatula number 113 with striated angled handle - Hu-Friedy - Delynov

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

The Hu-Friedy #113 retraction cord packer is a precision manual instrument used in restorative dentistry and prosthodontics. It consists of a thin, angled working end mounted on a #6 serrated handle. This large, textured handle is designed to provide an optimal grip, reducing muscle fatigue during gingival retraction procedures. Manufactured by Hu-Friedy Mfg. Co., LLC, this instrument benefits from the expertise of a manufacturer renowned for the quality of its steels and the finish of its surgical devices. Its structure is specifically adapted to handle retraction cords of different diameters without slipping.

What are the clinical indications for this instrument?

The use of the angled retraction cord packer is primarily indicated during prosthetic preparation stages. It is used for inserting the retraction cord into the sulcus, a crucial step to clear the cervical margins of a preparation before an optical or physico-chemical impression. In oral surgery and conservative dentistry, this dental retraction cord instrument is used to ensure perfect visibility of the operative field and to control sulcular fluid. Its specific angle allows reaching posterior sectors where access is limited, guaranteeing a homogeneous positioning of the cord around the entire periphery of the tooth, whether for crowns, bridges, or veneers.

What are the technical characteristics of the #113 packer?

The Hu-Friedy #113 retraction cord packer is distinguished by its thin, angled working end, optimized for sliding the cord under the free gingiva. The #6 handle is a large-diameter handle with a serrated surface, promoting superior tactile control. This design allows the practitioner to apply precise axial force without the risk of slipping. As a Class I instrument, it meets the manufacturing quality requirements of Hu-Friedy Mfg. Co., LLC. The geometry of the packer is designed not to traumatize periodontal tissues while being rigid enough to effectively push the gingival retraction cord into the narrowest spaces.

What are the contraindications for using this instrument?

Although the raw MDR text does not specify direct medical contraindications, the use of the angled retraction cord packer should be avoided on gingival tissues presenting severe acute inflammation or non-stabilized periodontitis, unless there is an absolute clinical necessity. Use is strictly reserved for qualified healthcare professionals. Excessive pressure during cord insertion with this instrument could lead to iatrogenic gingival recession or damage to the epithelial attachment. The integrity of the instrument should be checked before each use to ensure the absence of deformation or corrosion that could compromise patient safety.

What are the maintenance precautions for this non-resorbable instrument?

As a reusable Class I metallic instrument, the angled retraction packer must follow a rigorous sterilization protocol after each use. Although composition details are not specified in the source data, Hu-Friedy instruments are generally designed to withstand standard autoclave cycles. It is imperative to read the manufacturer's instructions carefully before the first use. Prior cleaning must remove all biological residue or cord debris to ensure sterilization efficacy. Proper maintenance of the serrated handle is necessary to maintain its anti-slip properties and ensure the longevity of the instrument in the dental practice.

Who is the manufacturer and what standards are respected?
