Forest for Dental Implant VIS BENEX Ø 2.1 mm, length 16 mm - Helmut Zepf (12.300.75) - Delynov

What is the set of 2 Helmut Zepf root extraction screws?

This set includes two specific extraction screws designed by the manufacturer Helmut Zepf Medizintechnik GmbH for use with the Benex system. These instruments are intended for the vertical extraction of roots. Each screw has a diameter of 2.1 mm and a length of 16 mm, providing a solid grip in the root canal or remaining tooth structure. The design of these screws allows for the transformation of rotational force into stable fixation, necessary for the application of axial traction force. This device is part of a minimally invasive surgical approach, aiming to preserve alveolar bone volume for future rehabilitations.

What are the clinical indications for these Benex system screws?

The use of the 16mm benex screw is primarily indicated in oral surgery for the extraction of fractured roots, residual roots, or teeth with severely decayed crowns. It is particularly useful in cases where the preservation of the buccal bone plate is critical, such as when preparing a site for immediate or delayed implantation. By allowing purely vertical extraction, these screws avoid lateral rocking movements that could damage the alveolar walls. They thus find their place in implant surgery and periodontology protocols where tissue integrity is a priority.

What are the technical characteristics of the 12.300.75 root extraction screw?

The extraction screw referenced 12.300.75 by Helmut Zepf features precise specifications to meet the constraints of root extraction. With a diameter of 2.1 mm, it is suitable for small-caliber roots, while its 16 mm length ensures deep and secure anchoring. The thread geometry is optimized for efficient insertion into the dentin without causing premature root splitting. These dimensions allow for full compatibility with the traction components of the original Benex extraction system. Helmut Zepf's manufacturing precision guarantees reliable force transmission during the vertical root luxation phase.

What are the contraindications for the use of these extraction screws?

Although specific manufacturer data does not list exhaustive contraindications, the use of the root extraction screw is generally contraindicated in situations where the remaining root structure is too fragile or too thin to support the pressure of the thread without shattering. Similarly, an uncontrolled acute infection at the surgical site may constitute a temporary contraindication. Practitioners must evaluate the quality of the potential anchorage via prior radiographic examinations. As with any surgical instrument, a known allergy to the metallic components of the device (although not specified here) must be taken into account before the intervention.

What are the precautions for use and maintenance for these screws?

To ensure the safety and efficacy of the 16mm benex screw, it is crucial to follow the cleaning, disinfection, and sterilization protocols recommended by Helmut Zepf Medizintechnik GmbH. Before each use, the integrity of the thread must be checked; any deformation or blunting of the tip can compromise anchoring and increase the risk of slippage. During insertion, adequate pre-drilling with the corresponding drill from the Benex system is essential to avoid root fracture. These screws are precision instruments that must be handled with care to maintain their mechanical properties during repeated autoclave sterilization cycles.

Who is the manufacturer and what standards are respected?

These screws are manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of dental and surgical instrumentation. Although the exact regulatory class and specific CE marking are not detailed in the source data provided, Helmut Zepf products are designed according to high quality standards specific to the German medical industry. Healthcare professionals are invited to refer to the instructions for use and product labeling to verify current certifications and specific safety instructions. Delynov ensures the distribution of these technical devices to meet the needs of specialized oral surgery practices.
