SERALENE non-absorbable blue (7/0) DR-9 needle 75 CM box of 24 sutures - Serag & Wiessner (LO05340A) - Delynov

What is the non-absorbable blue SERALENE suture (7/0)?

SERALENE from the Serag-Wiessner brand is a synthetic non-absorbable suture presented as a monofilament. This device is distinguished by its blue color, offering optimal visibility in the surgical field. As a 7/0 monofilament suture, it features a smooth surface that reduces tissue drag and limits bacterial plaque accumulation along the thread. This product is specifically designed for interventions requiring great precision and prolonged mechanical stability, as it does not undergo degradation by hydrolysis or enzymatic action in the tissues.

What are the clinical indications for this suture in surgery?

This 7/0 surgical suture is primarily indicated for oral micro-surgery, periodontology, and implantology procedures. Its very fine calibre (USP 7/0) is ideal for managing delicate flaps, papilla sutures, or connective tissue grafts. The blue dental suture thread allows the practitioner to perform precise stitches with minimal tissue trauma. Its non-absorbable nature guarantees the maintenance of necessary tension throughout the critical healing phase, particularly in areas subject to moderate mechanical stress.

What are the technical characteristics of the DR-9 needle?

The product referenced under code LO05340A by Serag-Wiessner is equipped with a DR-9 needle swaged onto a 75cm thread. The DR-9 needle is designed to provide precise penetration through gingival tissues while minimizing the risk of tearing. The 75cm thread length offers sufficient handling ease to multiply stitches if necessary during the same intervention. The combination of a 7/0 calibre and a small-sized needle meets the requirements of micro-surgery protocols where the workspace is restricted.

What are the contraindications for the use of this suture?

As with any non-absorbable suture medical device, the use of SERALENE is contraindicated in patients with a known hypersensitivity to synthetic polymers. Although composition specificities are not detailed here, caution is advised in case of active infection at the surgical site, as any foreign body can promote the persistence of infection. It is not recommended to use this thread in tissues requiring short-term natural absorption or in situations where tissue growth could be hindered by a permanent thread.

What are the precautions related to the non-absorbable nature of the thread?

Being a non-absorbable suture, SERALENE must be manually removed by the practitioner once clinical healing is achieved, generally after 7 to 14 days depending on the surgical protocol. Due to its monofilament structure, particular attention must be paid to the creation of knots to ensure their security; it is often advised to multiply half-hitches to prevent any slippage. The practitioner must take care not to damage the monofilament with sharp instruments during placement, in order to preserve the integrity of the thread's tensile strength.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Serag-Wiessner GmbH & Co. KG, a company recognized for its expertise in the production of surgical suture material. Although the regulatory class and specific CE marking are not mentioned in the current source data, the products of this manufacturer are developed according to rigorous quality standards specific to medical devices. For any precise information regarding certifications or compliance with the MDR regulation, it is imperative to refer to the instructions for use and labeling provided by Serag-Wiessner at the time of purchase.

State of the art

Modern synthetic sutures - absorbable or non-absorbable - are central to wound healing in oral surgery. Recent advances focus on reducing post-operative infections.
