x1 Benex extraction screw 8.5mm (be001 085) - Meisinger - Hager & Meisinger GmbH (47be001230085) - Delynov

What is the Meisinger Benex 8.5mm extraction screw?

The Benex 8.5mm extraction screw, referenced be001 085, is a high-precision technical component manufactured by Hager & Meisinger GmbH. This device is specifically designed for use within the Benex extraction system, a recognized method in oral surgery for axial and controlled root extraction. This 8.5mm screw allows for effective root anchorage, thus facilitating alveolar preservation procedures. It belongs to the category of surgical instruments for guided bone regeneration (GBR) and meets the rigorous quality standards of the Meisinger brand, guaranteeing perfect integration with the dedicated instrumentation.

What are the clinical indications for this extraction screw?

The use of the Benex extraction screw is indicated during dental surgeries requiring root extraction without damaging the alveolar bone walls or surrounding soft tissues. It is particularly requested in pre-implantology to maintain the integrity of the recipient site. According to the manufacturer Hager & Meisinger GmbH, the use of these surgical devices assumes adequate expertise and experience in dental implantology or maxillary surgery. The practitioner decides, under their sole responsibility, on the use of this Meisinger device on a case-by-case basis, depending on the clinical situation and the specific indication of the patient, notably for complex extraction cases where bone preservation is critical.

What are the technical characteristics of this device?

This extraction screw is characterized by a length of 8.5mm, dimensioned to offer optimal grip in the root canal. Identified under the technical reference 47be001230085 at Delynov, it is designed to withstand the axial traction stresses exerted during extraction. As a Class IIa device, it benefits from a robust design compliant with medical requirements. The precision of the threading is designed to ensure maximum stability once inserted. This Meisinger product is a key element of the Benex system, allowing for direct and secure force transmission for root removal, while limiting the risks of root fracture or damage to the bone ridges.

What are the contraindications for using the Benex screw?

Although the MDR text does not list specific medical contraindications related to materials, the use of the Benex extraction screw is strictly reserved for qualified professionals. Non-compliant use can lead to premature wear of the device and involve risks for patients and users. General contraindications related to oral surgery apply, such as uncontrolled systemic pathologies preventing surgical intervention. It is the responsibility of the dental surgeon to evaluate bone density and root condition before insertion to avoid any technical failure. Any use outside the framework provided by Hager & Meisinger GmbH for the Benex system is discouraged.

What are the precautions for use and maintenance?

The use of Meisinger surgical devices requires careful preoperative planning and in-depth knowledge of the associated surgical techniques. To ensure safety, any serious incident occurring in connection with the device must be reported to the manufacturer Hager & Meisinger GmbH and the competent authority. It is essential to check the condition of the screw before each intervention; wear or deformation of the threading compromises the efficiency of the extraction. The manufacturer regularly offers continuing education sessions to master the possible applications of its devices. Compliance with cleaning and sterilization protocols is imperative to maintain the performance of the Class IIa screw and ensure patient safety.

Who is the manufacturer and what standards are respected?

The Benex 8.5mm extraction screw is manufactured by Hager & Meisinger GmbH, a company based in Neuss, Germany, recognized for its expertise in high-quality dental instrumentation. This medical device is certified Class IIa and bears the CE0044 marking, attesting to its compliance with current European regulatory requirements.
