Surgical approximal root elevator for distal roots, Helmut Zepf model Fig. 77S (17.008.01TI) - Delynov

What is the Helmut Zepf Fig. 77S elevator?

The Fig. 77S approximal surgical elevator, referenced under code 17.008.01TI, is a precision manual instrument developed by the manufacturer Helmut Zepf Medizintechnik GmbH. This device is specifically designed for oral surgery procedures requiring a proximal approach. Its structure is adapted for the manipulation of dental roots, offering an optimized configuration to reach difficult-to-access areas. As a specialized instrument, it is integrated into complex extraction protocols where the use of a standard lever does not allow for sufficient angulation. Its design reflects the expertise of Helmut Zepf in the manufacture of surgical instrumentation dedicated to odontology.

What are the clinical indications for this instrument?

This instrument is primarily indicated for the extraction of distal roots in oral and implant surgery. The approximal elevator allows the surgeon to exert controlled force to break the periodontal ligament fibers and luxate the root. It is particularly useful during the avulsion of multi-rooted teeth or residual roots located in the posterior sector. Its use generally occurs after root separation or when a solid grip is necessary on the proximal face of the root to be extracted. The clinical objective is to facilitate avulsion while preserving the integrity of the alveolar walls, a crucial step for potential immediate or delayed implant placement.

What are the technical characteristics of the 17.008.01TI elevator?

The Helmut Zepf model 77S elevator is distinguished by its specific geometry adapted to distal roots. Although exact material details are not specified in the raw technical data, reference 17.008.01TI corresponds to Helmut Zepf Medizintechnik GmbH manufacturing standards for manual instrumentation. The working part is designed to insert effectively into the periodontal space. Its proximal shape allows for optimal force transmission during the lever movement. The design of the instrument is studied to offer a stable grip, allowing precise transmission of the torque necessary for root luxation without untimely slipping during the surgical procedure.

What are the contraindications for the use of this elevator?

Contraindications for the use of this surgical elevator are primarily related to the patient's clinical status and root morphology. Use of this instrument is discouraged if visual or spatial access is insufficient to guarantee a safe procedure, or in case of immediate proximity to critical anatomical structures (inferior alveolar nerve, maxillary sinus) without prior planning. As with any metallic instrument, a known hypersensitivity to the alloy components constitutes a contraindication. It is the practitioner's responsibility to evaluate bone density and root fragility to avoid any unwanted root fracture or injury to adjacent soft tissues when applying leverage force.

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

As a reusable surgical instrument, the Helmut Zepf elevator must undergo a rigorous decontamination, cleaning, and sterilization protocol after each use. It is imperative to follow the reprocessing instructions provided by the manufacturer Helmut Zepf Medizintechnik GmbH to ensure patient safety and instrument longevity. Cleaning must remove all organic debris, particularly in the gripping areas and on the working part. Before each intervention, the practitioner must inspect the instrument for any signs of wear, corrosion, or deformation that could compromise its effectiveness or the safety of the operative procedure.

Who is the manufacturer and what standards are respected?

The official manufacturer of this instrument is Helmut Zepf Medizintechnik GmbH, a recognized player in the field of dental and surgical instrumentation. Regarding specific certifications such as the regulatory class or CE marking, this information is not explicitly detailed in the provided technical documentation. However, as a medical device intended for invasive surgery, this product is manufactured according to the rigorous industrial quality standards inherent to German production. To obtain precise details on regulatory compliance (MDR), it is recommended to refer to the instructions for use or the declaration of conformity provided by Helmut Zepf with the instrument.
