SERALON non-absorbable blue (5/0) HR-15 needle 75 cm box of 24 sutures - Serag-Wiessner (VO103439) - Delynov

What is the SERALON 5/0 suture?

SERALON from the brand Serag-Wiessner is a non-absorbable synthetic surgical suture material. It comes in the form of a monofilament thread made of polyamide, which gives it an extremely smooth surface and excellent handling. This 5/0 blue suture thread is specifically colored with phthalocyanine blue (color index no. 74160) to ensure optimal visibility in the surgical field. Compliant with the European Pharmacopoeia monograph for sterile non-absorbable sutures, this device is a reliable choice for practitioners seeking a high-quality 5/0 nylon surgical suture. Its non-braided structure limits the accumulation of food debris and bacteria along the thread.

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. Due to its fineness (5/0 calibre) and its non-absorbable nature, it is indicated for the approximation of soft tissues during the placement of implants, gingival grafts, or periodontal surgeries. This blue oral surgery suture thread allows for primary intention healing by maintaining the wound edges without excessive tissue trauma. Its tensile strength is a major asset for securing flaps, although it should be noted that polyamide may gradually lose its tensile strength after prolonged implantation in the body.

What are the technical characteristics of the HR-15 needle?

Reference VO103439 is equipped with an HR-15 needle. According to the Serag-Wiessner technical nomenclature, the 'HR' code designates a 1/2 circle round-point needle. This profile is specifically indicated for deep sutures and ligatures, as it allows for traversing tissues without a cutting effect, thus reducing the risk of tearing fragile structures. The number '15' indicates a needle body length of 15 mm. Coupled with a 75cm long thread, this needle offers precision adapted to the restricted spaces of the oral cavity, allowing the dental surgeon to perform smooth passes even in posterior areas.

What are the contraindications for the use of this suture?

The use of SERALON is subject to several strict contraindications defined by the manufacturer Serag-Wiessner GmbH & Co. KG. This material is formally contraindicated for any direct contact with the heart, the central nervous system, or the central circulatory system. Furthermore, it must not be used in patients with a known allergy to polyamide or the mentioned dyes. An important point of vigilance concerns long-term stability: this thread should not be used when prolonged and permanent stability of the suture is essential, as polyamide undergoes a slow loss of tensile strength over time in the human body.

What are the precautions regarding knots and handling?

As a non-absorbable monofilament suture, SERALON exhibits the characteristic elasticity of polyamide threads. To guarantee the security of the assembly and prevent knot slippage, the manufacturer recommends performing one or two additional knots compared to braided threads. This precaution ensures the strength of the suture despite the smooth surface of the material. Furthermore, like any foreign body, prolonged contact with saline solutions (such as in the biliary or urinary tracts) can promote stone formation, although this risk is limited in standard oral surgery. Handling must be precise to avoid damaging the monofilament structure with sharp instruments.

Who is the manufacturer and what standards are respected?

The SERALON suture is manufactured by Serag-Wiessner GmbH & Co. KG, a recognized manufacturer based in Naila, Germany. This medical device is classified as Class IIb according to current regulations. It benefits from the CE1014 marking, guaranteeing its compliance with European safety and performance requirements. Each box contains 24 sterile sutures, ready for use. The product is designed to meet the standards of the European Pharmacopoeia, offering healthcare professionals a high-performance and secure seralon 5/0 suture solution. This product is often considered by practitioners as a filapeau equivalent for procedures requiring a reliable 5/0 non-absorbable suture.

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.
