Filter retention spatula CSI1 handle number 41 striated - Hu-Friedy - Delynov.

What is the Hu-Friedy #CSI1 retraction cord spatula?

The #CSI1 retraction cord spatula from the Hu-Friedy brand is a specialized manual instrument used in dentistry for soft tissue management. It consists of a thin working part adapted to the sulcular space, mounted on a #41 serrated handle. This specific handle is designed to ensure a firm grip, thus preventing slippage during the application of controlled pressure. Manufactured by Hu-Friedy Mfg. Co., LLC, this spatula meets the quality requirements of practitioners performing fixed prosthesis or conservative dentistry procedures requiring increased visibility of subgingival margins.

What are the clinical indications for this instrument?

This cord insertion instrument is primarily indicated during procedures requiring mechanical gingival retraction. In oral and prosthetic surgery, the Hu-Friedy #CSI1 spatula allows for the delicate placement of the retraction cord into the sulcus. This step is crucial for obtaining a high-precision impression, whether physical or digital, by clearing the preparation margins. It is also used during the placement of Class II or V direct restorations to isolate the operative field from crevicular fluid and blood, thus ensuring the seal of the bonding or filling.

What are the technical characteristics of the #CSI1 spatula?

The #CSI1 spatula is distinguished by its thinness and the configuration of its #41 handle. The active part is dimensioned to penetrate the gingival sulcus without excessive trauma, allowing the retraction cord to be packed with measured force. The serrated handle is a key element of its design, providing a texture that improves the tactile control of the dental surgeon, even in a wet environment. This device is classified as a Class I instrument according to current regulations, highlighting its professional use for non-invasive or minimally invasive interventions in the oral cavity.

What are the contraindications for the use of this instrument?

The use of the Hu-Friedy dental retraction cord spatula is contraindicated in the presence of gingival tissues showing severe acute inflammation or non-stabilized periodontitis, where retraction could worsen attachment loss. Although the manufacturer Hu-Friedy does not list specific medical contraindications in the provided data, clinical prudence dictates avoiding any excessive pressure on the epithelial attachment to prevent iatrogenic gingival recession. Use is strictly reserved for qualified healthcare professionals who have read the instructions for use.

What are the maintenance and handling precautions?

As a non-resorbable and reusable Class I instrument, this spatula must follow a strict cleaning, disinfection, and sterilization protocol between each patient. It is imperative to check the integrity of the working part before each use to ensure that no deformation or roughness is present, which could injure soft tissues. Handling must be precise to avoid damaging the sulcus. Storage must be in a dry and clean environment, in accordance with standard recommendations for dental surgical instrumentation to maintain the longevity of the steel.

Who is the manufacturer and what standards are respected?

The device is manufactured by Hu-Friedy Mfg. Co., LLC, located at 3232 N. Rockwell St. Chicago, IL 60618 USA. Hu-Friedy is a recognized manufacturer in the dental sector for the quality of its instruments. This product is listed as a Class I device.
