SERAFIT absorbable violet (5/0) HR-17 needle 70 CM box of 24 sutures - Serag & Wiessner (6O103276) - Delynov

What is violet absorbable SERAFIT (5/0)?

Violet absorbable SERAFIT is a synthetic surgical suture material produced by Serag-Wiessner. It comes in the form of a braided multifilament designed from a homopolymer of glycolic acid. This Class III medical device is specifically developed to offer high flexibility during handling. Its braided structure can be coated with calcium stearate with polycaprolactone or polyglycolic acid to improve trans-tissue passage. This 5/0 calibre thread is packaged in boxes of 24 sutures, each thread measuring 70cm long, ensuring sufficient length for complex procedures in the practice.

What are the clinical indications for this dental suture purchase?

The purchase of SERAFIT dental sutures is indicated for soft tissue approximation and performing ligatures. In oral and implant surgery, this material is used for the closure of hollow organs and surgical sutures requiring a synthetic absorbable material. Thanks to its multifilament nature, it ensures excellent knot security, which is crucial during gingival reconstruction procedures or graft placement. The manufacturer Serag-Wiessner GmbH & Co. KG specifies that its use is suitable for situations where resorption by hydrolysis is desired, thus avoiding a second intervention for suture removal.

What are the technical characteristics of the HR-17 needle?

The SERAFIT suture (6O103276) is equipped with an HR-17 needle. According to technical nomenclature, the HR code designates a 1/2 circle round-bodied needle. This configuration is specifically indicated for deep sutures and ligatures, as the round point allows for passing through tissues without excessive cutting, thus preserving the integrity of fragile structures. The number 17 indicates a needle length of 17 mm. This dimension is particularly suited to the restricted spaces of the oral cavity, allowing practitioners high precision when passing through periodontal tissues or when fixing flaps.

What are the contraindications for the use of SERAFIT?

The use of SERAFIT is contraindicated in clinical situations where long-term or prolonged stability of the suture material is required. Due to its absorbable nature, it cannot maintain tissue tension indefinitely. Furthermore, this device must never be used in patients with a known allergy to any of its components, notably glycolic acid, calcium stearate, or polycaprolactone. The manufacturer also emphasizes that the use of absorbable sutures may be inadequate in tissues with poor blood supply, as this can lead to suture extrusion or delay the normal resorption process.

How does resorption occur and what are the precautions?

Resorption of SERAFIT occurs via hydrolysis in the tissues, transforming the polymer into glycolic acid which is then metabolized by the body. This process results first in a loss of tensile strength, estimated at approximately 60% of its initial value after 14 days in vitro. Total mass loss of the thread occurs later, with complete resorption finished after approximately 90 days in vivo. Practitioners must exercise caution in patients with delayed wound healing. It is imperative to master specific surgical techniques, as requirements vary according to the clinical indication and the in vivo characteristics of the material.

Who is the manufacturer and what standards are respected?

This device is manufactured by Serag-Wiessner GmbH & Co. KG, a recognized manufacturer located in Naila, Germany. The SERAFIT product carries the CE1014 marking, certifying its compliance with European regulatory requirements for medical devices. Categorized as Class III, it meets the strictest safety standards for absorbable surgical implants. Each box contains 24 sterile units, identified by the reference 6O103276. Compliance with these standards guarantees dental surgeons reliable material for their daily oral surgery interventions, ensuring traceability and rigorous manufacturing quality.

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.
