Round tungsten carbide surgical bur, diameter 0.31mm - Helmut Zepf (08.902.031HF) - Delynov

What is the Helmut Zepf 0.31 mm round surgical bur?

The Helmut Zepf round surgical bur (reference 08.902.031HF) is a precision rotary instrument designed for specialized interventions. Manufactured from hard metal, this carbide surgical bur is distinguished by its hardness and its ability to maintain an effective cutting edge when cutting mineralized tissues. Its round shape and extremely fine diameter of 0.31 mm make it a tool of choice for practitioners requiring high precision. This device is developed by Helmut Zepf Medizintechnik GmbH, a manufacturer recognized for its high-quality instruments for oral and implant surgery.

What are the clinical indications for this carbide surgical bur?

This carbide surgical bur is indicated for procedures requiring extremely precise removal of material. In oral surgery, it is used for creating micro-access, removing root fragments, or creating guide grooves. Its small size of 0.31 mm allows for intervention in narrow anatomical areas where a standard bur would be too invasive. It finds application in minimally invasive endodontic surgeries or during the preparation of specific bone sites. The use of hard metal guarantees constant performance on enamel, dentin, or cortical bone.

What are the technical characteristics of reference 08.902.031HF?

Technical reference 08.902.031HF corresponds to a round-shaped bur with a working diameter of 0.31 mm. Its hard metal composition, often referred to as surgical tungsten carbide, gives it superior wear resistance compared to classic stainless steel burs. This technical characteristic is essential for limiting thermal heating during cutting, provided that recommended irrigation protocols are followed. Its geometry is optimized for debris evacuation, thus ensuring constant visibility of the operative field during milling.

What are the contraindications for the use of this instrument?

Contraindications for the use of this Helmut Zepf bur are mainly related to the physical limits of its 0.31 mm diameter. It must not be used for significant osteotomy volumes or massive clearances, as this risks causing instrument breakage due to mechanical overload. As with any hard metal rotary instrument, its use is prohibited without adequate irrigation, as heating could cause necrosis of the surrounding tissues. The practitioner must ensure the absence of known patient hypersensitivity to the metal components of the alloy before any intervention.

What are the maintenance precautions for this hard metal bur?

To maintain the cutting performance of the dental tungsten carbide bur, a rigorous cleaning and sterilization protocol must be followed in accordance with the instructions from the manufacturer Helmut Zepf Medizintechnik GmbH. Although hard metal is extremely resistant, it can be sensitive to sudden thermal shocks or certain corrosive chemical agents. It is recommended to inspect the condition of the blades under magnification after each sterilization cycle. Any sign of dulling or deformation must lead to the immediate replacement of the bur to ensure patient safety and the effectiveness of the surgical act.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a German company specializing in advanced surgical instrumentation. Regarding standards and regulatory classification, the user is invited to systematically refer to the product labeling and the instructions for use provided by the manufacturer to verify the specific certifications in force. Helmut Zepf is recognized for applying strict manufacturing standards, ensuring the traceability and quality of its rotary instruments. Compliance with safety requirements is a prerequisite for the use of these devices in a clinical environment.
