PERIODONTAL KNIFE FIG. 3. ORBAN 1/2 MODIFIED. DOUBLE-ENDED. RED-VIOLET BIONIK HANDLE - Helmut Zepf (46.040.09) - Delynov

What is the Helmut Zepf 46.040.09 periodontal knife?

The Fig. 3 Orban 1/2 modified periodontal knife is a manual surgical instrument designed by Helmut Zepf Medizintechnik GmbH. This double-ended device is manufactured from high-quality medical stainless steel to ensure optimal resistance during soft tissue interventions. It is distinguished by its red-violet Bionik handle, offering specific ergonomics for periodontology procedures. As a Class I instrument, it meets the regulatory requirements for non-invasive or short-term invasive medical devices used in dental practices.

What are the clinical indications for the orban knife?

The orban knife is primarily indicated for periodontal surgery, specifically for the excision of interproximal gingival tissues. Its use is recommended during gingivectomies to remove periodontal pocket walls or during gingivoplasties to reshape the gingiva and restore physiological architecture. Thanks to its two working ends, it allows access to narrow areas and performs precise incisions in interdental spaces, thereby facilitating the surgeon's work during the treatment of periodontal diseases or the aesthetic adjustment of soft tissues.

What are the technical characteristics of this instrument?

This model (reference 46.040.09) features a double-ended configuration based on the Orban 1/2 design, but with a specific modification to improve clinical access. The instrument is equipped with a Bionik handle, a signature series from Helmut Zepf, recognizable by its red-violet color. The structure is entirely made of medical stainless steel, a material selected for its biocompatibility and its ability to maintain an effective cutting edge. It is a non-sterile instrument upon delivery, requiring a full reprocessing cycle before each use in a surgical environment.

What are the contraindications for the use of this instrument?

The main medical contraindication mentioned by the manufacturer Helmut Zepf concerns hypersensitivity or intolerance to metals. Contact with medical stainless steel can trigger a reaction in allergic patients. If such a hypersensitivity reaction occurs during the intervention, the procedure must be stopped immediately and the necessary clinical measures must be taken. It is therefore imperative to check the patient's allergic history before any manipulation with this manual instrument.

What are the maintenance and sterilization precautions?

Like any periodontal surgery instrument, this knife must imperatively be cleaned, disinfected, and sterilized before the first use as well as after each subsequent use. The manufacturer emphasizes the importance of thorough cleaning to remove all residue. Before each use, the practitioner must inspect the instrument for any visible damage such as cracks, breaks, or defects on the cutting edges. The use of damaged or worn products is strictly prohibited to ensure patient safety and the effectiveness of the surgical procedure.

Who is the manufacturer and what standards are respected?

The instrument is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. This periodontal knife is classified as a Class I medical device according to current regulations. The manufacturing process follows strict protocols to ensure compliance with health and safety requirements. The manufacturer specifies that reprocessing of the instrument is possible without a defined maximum limit, as this depends on the product design, observed wear, and the materials used. This device is exclusively reserved for qualified healthcare professionals.
