SERAFIT absorbable violet (4/0) DSS-13 needle 45 CM box of 24 sutures - Serag & Wiessner (6O15131L) - Delynov

What is the violet absorbable SERAFIT suture (4/0)?

SERAFIT from Serag-Wiessner is a Class III medical device intended for surgical suturing. It is a synthetic absorbable material of the braided multifilament type, designed from a polyglycolic acid homopolymer. To improve its sliding and handling properties, this thread is coated with calcium stearate combined with polycaprolactone or polyglycolic acid. Presented here in 4/0 calibre with a length of 45cm, this violet thread ensures excellent visibility in the operative field. Its braided structure guarantees remarkable flexibility and high knot security, meeting the requirements of oral and implant surgery interventions.

What are the clinical indications for this Serag-Wiessner device?

In accordance with data from the manufacturer Serag-Wiessner GmbH & Co. KG, the SERAFIT suture is indicated for tissue approximation and the performance of ligatures. In oral surgery, it is particularly suitable for closing hollow organs and for the coaptation of mucosal flaps. Its use is recommended for interventions requiring predictable absorption of the suture material. The practitioner can use it to secure extraction sites, fix regeneration membranes, or suture release incisions. The choice of material must, however, take into account specific surgical techniques and the in-vivo characteristics of the thread to guarantee optimal healing.

What are the technical characteristics of the DSS-13 needle?

The DSS-13 needle equipped on this SERAFIT suture is a 13mm long needle. According to the technical nomenclature, the DSS code designates a 3/8 circle needle equipped with an atraumatic reverse cutting triangular point. This geometry is specifically designed to penetrate delicate tissues and thin mucous membranes without causing excessive tearing. The 3/8 circle curvature facilitates the passage of the needle in restricted spaces, common in implantology or periodontology. Its atraumatic design ensures a smooth transition between the needle and the 45cm thread, minimizing tissue trauma during suture passage.

What are the contraindications for the use of the SERAFIT suture?

The use of the SERAFIT suture presents certain limits defined by the manufacturer Serag-Wiessner. It should not be used when tissues require mechanical stability or support from the suture material over a prolonged or long-term period. Furthermore, the use of this device is strictly contraindicated in patients with a known allergy to any of the components, notably polyglycolic acid or coating agents such as calcium stearate. It is also advised to be cautious when using absorbable sutures in tissues with low blood supply, as this could lead to suture extrusion or delayed absorption.

How does absorption occur and what precautions should be taken?

The absorption of the SERAFIT suture occurs through a chemical process of hydrolysis within the tissues. This mechanism transforms the homopolymer into polyglycolic acid, which is then metabolized by the body. In vitro, the breaking strength of the thread decreases by approximately 60% after 14 days. In vivo, total absorption of the thread mass is generally completed after approximately 90 days. Practitioners should note that absorption manifests first as a reduction in breaking strength before the loss of mass. Particular caution is required in patients with delayed healing, as degradation characteristics can influence tissue hold during the critical healing phase.

Who is the manufacturer and what standards are met by this product?

This suture is manufactured by Serag-Wiessner GmbH & Co. KG, a recognized company based in Naila, Germany. The SERAFIT product benefits from the CE1014 marking, certifying its compliance with European regulatory requirements for medical devices. Categorized as Class III, this device meets the strictest safety and performance standards for absorbable surgical implants. Each box contains 24 sterile ready-to-use sutures, identified under the reference 6O15131L. Compliance with these certifications guarantees dental surgeons and implantologists reliable material, whose traceability and manufacturing processes are rigorously controlled.

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.
