Long surgical screw-in device for Benex screws - Helmut Zepf (12.300.48) - Delynov

What is the Helmut Zepf long surgical screwing device (12.300.48)?

The long surgical screwing device, referenced under code 12.300.48, is a manual instrument designed by Helmut Zepf Medizintechnik GmbH. This specific component is intended for use with the screws of the Benex extraction system. Its elongated structure allows access to difficult clinical areas, particularly in posterior sectors or for deeply buried roots. As a precision instrument, it ensures the transmission of the torque necessary to firmly anchor the traction screw into the root structure. This device fits into the category of Guided Bone Regeneration (GBR) and preservative extraction surgery, offering a reliable solution for practitioners demanding high quality in their instrumentation.

What are the clinical indications for this instrument?

This instrument is indicated for all dental extraction procedures using the Benex technique, particularly when the anatomical configuration requires extraction screw screwing with an extended reach. It is used in oral surgery to prepare for the atraumatic extraction of single or multiple roots, allowing for the preservation of the integrity of the alveolar walls. The use of this long device is particularly recommended during immediate implant surgeries where alveolar bone preservation is critical. By facilitating Benex screw screwing, it allows for the efficient management of fractured or residual roots without resorting to invasive osteotomy, thus optimizing the site for future implantation or bone regeneration.

What are the technical characteristics of the 12.300.48 device?

The Helmut Zepf long screwing device is distinguished by its technical reference 12.300.48, guaranteeing exact compatibility with the dedicated Benex screws. Its design prioritizes an increased shaft length compared to standard models, offering better visibility and easier access to restricted operative sites. The working part is machined to fit perfectly into the screw socket, avoiding any slipping or deformation during the application of rotational force. Manufactured by Helmut Zepf Medizintechnik GmbH, this instrument meets the durability and mechanical resistance requirements necessary for repeated interventions in a surgical environment. Its finish allows for cleaning and sterilization in accordance with hospital and dental office hygiene protocols.

What are the contraindications for the use of this screwing instrument?

The contraindications for using this screwing instrument are mainly related to the limits of the Benex extraction system itself. It should not be used if the remaining root structure is insufficient to support the anchoring of the traction screw, or in cases of severe bone fusion (ankylosis) that does not allow for axial extraction. Furthermore, the use of this instrument is prohibited in case of known allergy to the metallic components of the instrumentation, although these devices are designed from biocompatible materials. Any clinical situation where visual access or the workspace is too restricted to guarantee a correct screwing axis also constitutes a relative contraindication, in order to avoid any risk of iatrogenic root fracture.

What are the maintenance precautions for this non-resorbable device?

As a non-resorbable metallic surgical instrument, the Helmut Zepf long screwing device requires a rigorous reprocessing protocol after each use. The manufacturer's instructions regarding cleaning, decontamination, and autoclave sterilization should be followed. Particular attention must be paid to the screwing tip to ensure the absence of organic debris or scale deposits that could compromise the fit with the Benex screws. Practitioners must regularly inspect the instrument for any signs of wear or metal fatigue. Proper maintenance not only guarantees the longevity of the instrument but also ensures patient safety by preventing the risks of cross-contamination during oral surgery procedures.

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-precision surgical instrumentation. Although detailed regulatory specifications such as the exact class or CE marking are not explicitly listed in the provided source data, Helmut Zepf products are developed according to rigorous quality standards specific to dental surgery medical devices. Practitioners are invited to consult the instructions for use and product labeling to verify specific certifications and current safety recommendations. As a distributor, Delynov ensures the supply of devices from established manufacturers respecting the technical requirements necessary for the practice of modern implantology and oral surgery.
