2 tractor cables for BENEX 48mm extractor - Helmut Zepf (12.300.20) - Delynov

What is the 48mm traction cable for the BENEX extractor?

The 48mm traction cable for the BENEX extractor is an essential benex extractor accessory for the operation of the atraumatic extraction system developed by Helmut Zepf. This device comes in the form of a 48mm long traction cable, designed to connect the extraction screw fixed in the tooth root to the extractor hook. This component allows the rotational movement of the device handle to be transformed into a pure vertical traction force. Manufactured by Helmut Zepf Medizintechnik GmbH, this cable is specifically calibrated to withstand mechanical stress during the avulsion of roots or root fragments, guaranteeing reliable and precise force transmission throughout the surgical intervention.

What are the clinical indications for this device?

The use of this benex extractor cable is indicated for the controlled extraction of single-rooted tooth roots as well as root fragments. This technique is particularly recommended when the preservation of soft tissues and surrounding bone structures is essential, especially within the framework of immediate loading protocols or buccal plate preservation. The system also allows for extrusion, defined as the atraumatic repositioning of a tooth root out of its socket for splinting fixation. In the case of multi-rooted roots, the manufacturer Helmut Zepf specifies that these must imperatively be separated beforehand in order to extract each fragment individually in an axial manner.

What are the technical characteristics of this accessory?

The benex extractor cable, referenced under code 12.300.20 by Helmut Zepf, has a specific length of 48mm. It is designed to integrate perfectly into the Benex protocol which requires preliminary drilling with a diamond twist drill to a depth of approximately 7mm into the hard tissues. The cable is hooked to the extraction screw (long or short depending on the clinical situation), then guided over a deflection pulley before being fixed to the extractor hook. This technical configuration allows for axial mobilization without transverse movements, thus protecting the integrity of the socket. This device belongs to the category of consumables for the original Benex extraction system.

What are the contraindications for the use of this cable?

Although the regulatory text does not list absolute medical contraindications related to the material itself, the use of this benex cable is subject to strict compliance with the operative protocol. A major technical contraindication lies in the extraction of multi-rooted teeth without prior root separation. If the roots are not divided, the axial traction force cannot be exerted correctly, risking damage to the equipment or anatomical structures. Furthermore, a drilling that is not located in the axis and at the center of the root fragment can compromise the effectiveness of the traction exerted by the cable and the extraction screw.

What are the precautions for use and handling?

To guarantee the effectiveness of the traction cable, several precautions must be observed during the procedure. Before applying tension, it is necessary to sever the periodontal fibers (Sharpey's fibers) in the sulcus using a periotome. Long and strong roots must be previously mobilized axially for approximately 30 seconds with an elevator or a twister without transverse movements. During installation, the opening of the extractor support piece must be oriented in the buccal direction to maintain a direct view of the extraction screw and the cable. Correct alignment between the cable, the deflection pulley, and the screw is crucial to ensure a smooth extraction and minimize the risks of rupture under load.

Who is the manufacturer and what standards are respected?

This device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. The product is classified as a Class I medical device according to current regulations. As a high-precision dental extraction accessory, it meets the strict quality requirements imposed by Helmut Zepf for its entire oral surgery range. Compliance with Class I ensures that the device meets the safety and performance standards for non-invasive or temporary-use invasive surgical instruments, thus providing practitioners with reliable equipment for their daily avulsion and alveolar preservation procedures.
