SERAMON non-absorbable colorless (4/0) DS-18 needle 50 CM box of 24 sutures - Serag & Wiessner (MEO151714) - Delynov

What is colorless non-absorbable SERAMON (4/0)?

SERAMON marketed by Serag-Wiessner is a synthetic, monofilament, and non-absorbable surgical suture material. This medical device is distinguished by its polytetrafluoroethylene (PTFE) composition, a polymer recognized for its chemical inertness and extremely smooth surface. Offered here in a colorless version, it comes as a 4/0 caliber monofilament with a length of 50cm. Its non-braided structure limits bacterial adherence and facilitates passage through soft tissues without a sawing effect. This product complies with the requirements of the European Pharmacopoeia for sterile non-absorbable suture materials.

What are the clinical indications for this suture in surgery?

Serag-Wiessner SERAMON is indicated for soft tissue adaptation and ligation when a non-absorbable material is required. In oral and implant surgery, it is particularly suited for procedures requiring high biocompatibility and an absence of capillarity, such as gingival grafts or flap closures on extraction sites. The manufacturer specifies that this thread can also be used in the circulatory system and the central nervous system. Due to its stability, PTFE threads can also serve as stay sutures or marking tools during complex interventions.

What are the technical characteristics of the DS-18 needle?

The DS-18 needle equipped on this SERAMON suture (reference MEO151714) possesses specific properties for dental surgery. The 'DS' code designates a 3/8 circle needle featuring a triangular reverse cutting tip. This geometry is ideal for traversing dense or fibrous tissues without risk of tissue tearing, as the cutting edge is located on the convex curvature of the needle. The number '18' indicates a body length of 18mm, offering an optimal compromise between maneuverability in restricted spaces and gripping capacity for the practitioner. It is manufactured from high-quality surgical steel.

What are the contraindications for the use of this device?

The use of SERAMON is strictly contraindicated in patients with a known hypersensitivity or allergy to polytetrafluoroethylene (PTFE) or any other component of the device. Furthermore, the manufacturer Serag-Wiessner GmbH & Co. KG emphasizes that there is not yet sufficient experience regarding the use of this material in microsurgery, ophthalmology, or for interventions on peripheral nerves. The surgeon must evaluate the relevance of the material choice based on the mechanical characteristics required by the specific indication and the surgical technique employed.

How is a non-absorbable PTFE suture managed?

Unlike absorbable sutures that degrade by hydrolysis, PVDF or PTFE sutures like SERAMON are permanent and do not lose their tensile strength over time. This requires a secondary intervention for suture removal once tissue healing is achieved. Due to the very smooth surface of the monofilament, the practitioner must pay particular attention to knot construction to ensure their security and avoid any slippage. This type of colorless monofilament suture is preferred to minimize local inflammation and prevent dental plaque accumulation at the surgical site during the healing phase.

Who is the manufacturer and what standards are respected?

SERAMON is manufactured by Serag-Wiessner GmbH & Co. KG, a recognized manufacturer based in Germany. This medical device is classified as Class III, which corresponds to the highest level of requirement for surgical devices. It benefits from the CE1014 marking, guaranteeing its compliance with current European regulations. The product meets the standards of the European Pharmacopoeia (Ph. Eur.) monograph relating to sterile non-absorbable suture materials. Each box contains 24 ready-to-use sutures, ensuring full traceability and microbiological safety for surgical interventions in office or hospital settings.

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.
