SERAMON non-absorbable clear (4/0) DS-15 needle 50 CM box of 24 sutures - Serag & Wiessner (MEO151713) - Delynov

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

The SERAMON suture, developed by Serag-Wiessner, is a high-performance synthetic surgical suture material. It is a non-absorbable monofilament designed from polytetrafluoroethylene (PTFE). This device is distinguished by its monofilament structure which limits capillarity and the risk of bacterial colonization, a major asset in oral surgery. Offered exclusively in a non-colored (colorless) version, this thread has a USP 4/0 calibre, suitable for procedures requiring high precision. Its PTFE composition gives it excellent biocompatibility and fluid handling through soft tissues. This specific packaging (MEO151713) includes a box of 24 sterile sutures, each measuring 50 cm in length, meeting the requirements of practitioners for tissue adaptation or ligation interventions.

What are the clinical indications for SERAMON in surgery?

SERAMON from Serag-Wiessner is indicated for soft tissue adaptation or for performing ligatures when a non-absorbable suture material is required. Its physical properties allow for extensive use, including in sensitive areas such as the circulatory system and the central nervous system. In daily practice, these PTFE threads can also serve as support threads or as a means of surgical marking. Although the manufacturer specifies that experience is still insufficient in microsurgery, ophthalmology, or for interventions on peripheral nerves, its stability and chemical inertness make it a relevant choice for dental surgeons and implantologists seeking airtight and durable closure of flaps, particularly during bone regeneration procedures or implant placement.

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

The SERAMON suture (MEO151713) is equipped with a DS-15 type technical needle. According to the reference nomenclature, the 'DS' code designates a 3/8 circle needle equipped with a triangular reverse cutting point. This configuration is specifically designed to penetrate dense and fibrous tissues with minimal resistance, while avoiding involuntary tissue tearing thanks to its cutting edge positioned on the outer curvature. The number '15' indicates a needle body length of 15 mm. This dimension, combined with a 50 cm thread, offers an optimal balance for interventions in restricted areas, allowing the surgeon precise and secure handling when passing sutures through the oral mucosa.

What are the contraindications for the use of this PTFE suture?

The use of the SERAMON device is strictly contraindicated in patients with known allergies to any of its components, notably polytetrafluoroethylene (PTFE). The manufacturer Serag-Wiessner also emphasizes that the choice of suture material must imperatively take into account the specific characteristics of the product and the needs of the clinical indication. To date, clinical data are considered insufficient to recommend its use in microsurgery, ophthalmic surgery, or for interventions on peripheral nerves. It is the responsibility of the practitioner to carefully read the instructions for use and evaluate the benefit-risk ratio according to the surgical technique employed, as requirements vary considerably from one procedure to another.

How is a non-absorbable suture like SERAMON managed?

As SERAMON is a non-absorbable PTFE suture material, it does not undergo any degradation by hydrolysis or enzymatic proteolysis within the body. Unlike absorbable sutures, it retains its tensile strength indefinitely after implantation. This characteristic requires rigorous post-operative monitoring and generally necessitates a secondary intervention for the removal of sutures once soft tissue healing is achieved. During placement, the surgeon must pay particular attention to the knotting technique to guarantee the stability of the knots, as PTFE is a very smooth material. However, its monofilament structure ensures atraumatic removal and limits the accumulation of dental plaque along the thread during the healing phase.

Who is the manufacturer and what standards are respected by this device?

SERAMON is manufactured by Serag-Wiessner GmbH & Co. KG, a company based in Naila, Germany. This medical device is classified as Class III, which corresponds to the highest level of regulatory requirement for surgical devices. It benefits from the CE1014 marking, certifying its compliance with European safety and performance requirements. Furthermore, Serag-Wiessner suture materials comply with the specifications of the current edition of the European Pharmacopoeia (Ph. Eur.) monograph relating to sterile non-absorbable suture materials (fila non resorbilia sterilia). Only negligible deviations concerning the thread diameter compared to the monograph may be observed, thus guaranteeing a product of constant high quality for operating theaters.

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, optimizing keratinized gingival tissue thickness, and innovating composite materials.
