SERALON non-absorbable blue (5/0) DS-12 needle of 75 CM box of 24 sutures - Serag & Wiessner (VO103412) - Delynov

What is the blue non-absorbable SERALON (5/0)?

SERALON by the brand Serag-Wiessner is a synthetic, non-absorbable surgical suture material. It consists of polyamide, a polymer offering high flexibility and a smooth surface. This surgical suture thread comes in the form of a monofilament, which considerably reduces the risks of capillarity and the transport of microorganisms compared to braided threads. Its blue color, obtained by adding phthalocyanine blue, ensures excellent visibility in the operative field, thus facilitating the identification and subsequent removal of stitches. This Class IIb medical device meets the requirements of the European Pharmacopoeia for sterile non-absorbable sutures.

What are the clinical indications in oral surgery?

Although the general intended use is surgical suture, SERALON (5/0) is particularly suitable for oral and implant surgery procedures requiring high precision. Its fine 5/0 calibre allows for the manipulation of delicate tissues, such as alveolar mucosa or keratinized gingiva during gingival grafts or flap closures after implant placement. Due to its non-absorbable nature, it maintains constant tension throughout the initial healing phase without degrading prematurely. Practitioners frequently use it for interrupted or continuous sutures where minimal tissue reaction is sought.

What are the technical characteristics of the DS-12 needle?

The DS-12 needle accompanying this Serag-Wiessner suture thread has specific technical features for dense tissues. The DS prefix designates a 3/8 circle needle equipped with a reverse cutting triangular tip. This geometry is ideal for passing through resistant tissues without causing accidental tearing towards the wound edge, as the cutting edge is located on the outer curvature. The number 12 indicates a length of 12 mm, offering a compact radius of curvature suitable for the restricted spaces of the oral cavity. Combined with a 75cm thread, this needle allows for fluid and precise movement during periodontal or implant sutures.

What are the contraindications for the use of this suture?

According to data from the manufacturer Serag-Wiessner GmbH & Co. KG, the use of SERALON is strictly contraindicated in direct contact with the heart, the central nervous system, or the central circulatory system. Furthermore, this material must not be used when prolonged and permanent stability of the suture is essential, as a progressive loss of tensile strength may occur in the body over the long term. Finally, its use is prohibited in patients with known hypersensitivity or allergies to polyamide or phthalocyanine blue dye (color index no. 74160).

What are the precautions related to handling and knots?

As SERALON is a polyamide monofilament thread, it exhibits characteristic elasticity and shape memory. To guarantee the security of the suture and prevent any slippage, the manufacturer recommends performing one or two additional knots compared to standard braided threads. This precaution ensures the strength and stability of tissue apposition. Moreover, like any foreign body, prolonged contact with saline solutions (biliary or urinary tracts) can promote the formation of calculi. In oral surgery, it is imperative to plan for the removal of sutures once clinical healing is achieved, as the thread is non-absorbable.

Who is the manufacturer and what standards are respected?

This device is manufactured by Serag-Wiessner GmbH & Co. KG, a recognized company based in Naila, Germany. The product benefits from the CE1014 marking, certifying its compliance with European regulatory requirements for Class IIb medical devices. The suture material is produced according to the standards of the current edition of the European Pharmacopoeia (EP) monograph relating to sterile non-absorbable sutures. Each box contains 24 sutures of 75cm in length, sterilely packaged under technical reference VO103412, guaranteeing optimal traceability and safety for surgical procedures in dental practices or hospital environments.

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.
