Apical root elevator with finger rest, model Fig. 302 - Helmut Zepf (17.302.00) - Delynov

What is the Fig. 302 Helmut Zepf apical root elevator?

The Fig. 302 apical root elevator, referenced under code 17.302.00 at Delynov, is a precision manual instrument designed by Helmut Zepf Medizintechnik GmbH. This device is distinguished by its optimized structure for reaching deep root segments. Its configuration includes an ergonomic handle equipped with a specific finger-rest, allowing the practitioner to exert controlled force during luxation. As an instrument in the INSTRU category, it meets the requirements of oral surgery for root mobilization. Its robust design ensures efficient transmission of the lever movement necessary to separate the root from its socket without compromising the integrity of the surrounding bone structures.

What are the clinical indications for this instrument?

This Helmut Zepf elevator is primarily indicated for the extraction of root fragments and fractured roots located in the apical position. In oral surgery and implantology, it is used during exodontia phases where standard forceps cannot ensure sufficient grip. Its use is recommended for initial luxation, allowing for the creation of space between the root and the alveolar bone. It is particularly useful in cases of ankylosed roots or during root clearance procedures before implant placement. The thinness of its working part allows for precise insertion into the periodontal space to facilitate the expulsion of the root by an adapted rotation and lever movement.

What are the technical characteristics of the 17.302.00 elevator?

The Helmut Zepf apical root elevator, model Fig. 302, features technical specifications centered on clinical performance. Reference 17.302.00 designates an instrument equipped with a strategically placed finger-rest to improve stability when applying axial and rotational forces. The active part is designed to insert with precision into narrow areas of the apex. Unlike suturing devices, this instrument does not have a needle but a rigid blade adapted to the mechanical constraints of exodontia. The manufacturing quality of Helmut Zepf Medizintechnik GmbH guarantees high resistance to repeated sterilization cycles, thus ensuring operational longevity in a demanding surgical environment.

What are the contraindications for the use of this elevator?

The use of the Fig. 302 elevator is contraindicated in situations where the integrity of the adjacent alveolar bone must be absolutely preserved without any lateral pressure, or when the root is in immediate proximity to critical anatomical structures (inferior alveolar nerve, maxillary sinus) without sufficient visibility. As with any metallic instrument, its use is prohibited in patients with a known hypersensitivity to the metals constituting the alloy, although these cases are rare in clinical practice. It must not be used as a lever with excessive force on healthy adjacent teeth, at the risk of causing unwanted luxations or crown fractures on the supporting teeth.

What are the maintenance and durability precautions?

Being a non-resorbable instrument intended for repeated use, this Helmut Zepf elevator requires a rigorous decontamination and sterilization protocol after each intervention. The manufacturer's recommendations regarding autoclave cleaning should be followed to prevent corrosion and maintain the mechanical properties of the steel. The finger-rest and gripping areas must be carefully inspected to remove any biological residue. Periodic lubrication of moving parts, if applicable, or a check of the sharpness of the working part is advised to ensure constant cutting and luxation efficiency. Storage in a dry and protected environment is essential to preserve the instrument's finish.

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. Although the regulatory class specifications and CE marking are not explicitly detailed in the current source data, Helmut Zepf products are developed according to rigorous industrial quality standards specific to German manufacturing. Practitioners are invited to consult the instructions for use and the labeling of the delivered product to verify specific certifications, reprocessing instructions, and compliance with current medical device regulations. Traceability is ensured by the technical reference 17.302.00 provided by Delynov.
