Surgical drill for bone drilling, diameter 1.1mm, depth 9mm - Helmut Zepf (08.523.11) - Delynov

What is the Helmut Zepf 08.523.11 surgical bur?

The Helmut Zepf surgical bur (reference 08.523.11) is a high-precision rotary instrument specifically designed for bone drilling procedures in a surgical environment. This device is distinguished by a working diameter of 1.1 mm and a penetration capacity of 9 mm. Manufactured by Helmut Zepf Medizintechnik GmbH, this bur is a cutting tool intended for use on a suitable handpiece. Its structure is optimized to ensure efficient evacuation of bone debris during rotation, while ensuring the guiding stability necessary for the first stages of implant or periodontal preparation.

What are the clinical indications for this drilling instrument?

This 1.1 mm bur is primarily indicated in oral and implant surgery for performing pilot drilling or precise marking of bone sites. Its thinness allows the practitioner to define the insertion axis with great accuracy before using larger diameter drills. It is also used for creating anchoring points in the cortex or for micro-perforations intended to promote revascularization during bone grafts. Its use extends to periodontal surgery procedures requiring access to or minor modification of the alveolar bone structure.

What are the technical characteristics of the 08.523.11 bur?

The technical characteristics of this Helmut Zepf instrument are based on a rigorous geometry adapted to the constraints of bone surgery. The diameter of the working part is 1.1 mm, offering an ideal compromise between thinness and mechanical resistance. The cutting depth is limited to 9 mm, allowing for visual and tactile control during penetration into hard tissues. The design of the cutting head is studied to minimize thermal heating during drilling, subject to adequate irrigation. Reference 08.523.11 ensures standard compatibility with the clamping systems of classic surgical contra-angles used in dental practices.

What are the contraindications for the use of this surgical bur?

Contraindications for the use of the Helmut Zepf bur include any clinical situation where bone thickness or density is insufficient to support 9 mm drilling without the risk of damaging adjacent anatomical structures, such as the mandibular canal or maxillary sinuses, without prior planning. Use is prohibited in cases of uncontrolled systemic pathology affecting bone healing. Additionally, the instrument must not be used if the practitioner notices visible wear on the blades or warping of the shaft, which could compromise the precision of the procedure or generate thermal necrosis of the surrounding tissues.

What are the maintenance and handling precautions?

Like any non-resorbable surgical rotary instrument, this bur requires a strict protocol of cleaning, disinfection, and sterilization before each use. It is imperative to follow the recommendations of the manufacturer Helmut Zepf Medizintechnik GmbH regarding autoclave cycles. During the surgical act, abundant and continuous irrigation is necessary to avoid overheating the bone. The practitioner must exert moderate pressure to prevent instrument breakage, particularly given its small diameter of 1.1 mm. Regular checking of the sharpness is essential to maintain cutting efficiency and patient safety.

Who is the manufacturer and what standards are respected?

The device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-quality surgical instrumentation. Although detailed specifications on the regulatory class or CE marking are not explicitly mentioned in the simplified technical documentation, the product is designed according to German industrial manufacturing standards. For any precise information regarding compliance with ISO standards or European Medical Device Regulations (MDR), it is recommended to systematically refer to the instructions for use and certificates of conformity provided by Helmut Zepf with the instrument.
