x2 root extraction screws for BENEX system 2.1mm, 10mm long - Helmut Zepf

What is the Helmut Zepf 2.1 mm screw for the BENEX system?

The screw for the BENEX system by the Helmut Zepf brand is a technical component with a 2.1 mm diameter and 10 mm length, delivered in a pack of two units. It is designed to be inserted into the dental root to serve as an anchoring point when using the Benex extraction kit. Its structure is optimized to guarantee sufficient primary stability within the dentin, thus allowing the application of the traction forces necessary for avulsion without damaging the surrounding alveolar walls.

What are the clinical indications for these extraction screws?

These screws are indicated for dental root extraction, particularly in situations where conventional extraction using forceps or elevators poses a risk to the integrity of the alveolar bone. They are used in oral surgery and implantology to extract fractured or deeply decayed roots. The use of this Helmut Zepf equipment is part of an atraumatic extraction approach, aiming to maximize the preservation of bone and gingival volume before immediate or delayed implant placement.

What are the technical characteristics of these screws?

Helmut Zepf screws feature a diameter of 2.1 mm and a useful length of 10 mm. These dimensions are specifically calibrated to match the drills and traction instruments of the original Benex system. The thread geometry is designed to provide a firm grip in the hard tissues of the root, thus minimizing the risk of detachment or root fracture during the vertical traction phase. They are manufactured by Helmut Zepf Medizintechnik GmbH according to industrial precision standards.

What are the contraindications for the use of this device?

Contraindications for the use of these screws include clinical situations where the residual root exhibits excessive fragility, such as major internal or external resorption, which does not allow for the mechanical anchoring of the screw. Furthermore, they must not be used if the practitioner does not have the compatible Benex traction system. As with any surgical procedure, general contraindications related to the patient's health status (uncontrolled coagulation disorders, specific bone pathologies) must be evaluated by the dental surgeon before the intervention.

What are the maintenance and reuse precautions?

As instruments intended for dental root extraction, these screws must follow a rigorous decontamination and sterilization protocol between each patient, in accordance with the instructions from the manufacturer Helmut Zepf Medizintechnik GmbH. It is imperative to check the integrity of the thread and the absence of deformation or metal fatigue before each use. A blunt or damaged screw can compromise the success of the extraction or break in situ, then requiring more invasive surgical maneuvers for its removal.

Who is the manufacturer and what standards are respected?

The official manufacturer is Helmut Zepf Medizintechnik GmbH, a recognized company in the dental and surgical instrumentation sector. Although the specific regulatory class and CE marking are not detailed in the current technical sheet, these products are designed to meet the requirements of oral health professionals. For any precise information on certifications or compliance with international standards in force, it is recommended to refer to the instructions for use or the technical documentation provided by Helmut Zepf at the time of purchase.
