Extraction System Large Model Benex II - Helmut Zepf (12.302.00) - Delynov

What is the Benex II large model extraction system?

The Benex II system, developed by Helmut Zepf Medizintechnik GmbH, is a high-precision root extraction device. This demonstration model, referenced under code 12.302.00, is designed to provide a vertical extraction solution. Unlike conventional methods using luxators or forceps that exert lateral forces, this Benex dental extractor focuses on axial traction. The kit structure includes the necessary elements to anchor the device in the root and exert a controlled traction force, aiming to protect the integrity of surrounding tissues during oral surgery interventions.

What are the clinical indications for this atraumatic dental extractor?

The use of the Benex extraction kit is primarily indicated for the extraction of single roots or root fragments where preservation of the alveolar bone is an absolute priority. It is particularly useful in implantology to maintain bone and gingival architecture, thus avoiding fractures of the vestibular plate often associated with classic extractions. This Helmut Zepf system is also recommended for fractured or deeply decayed roots that do not allow for sufficient grip with standard instruments, thus guaranteeing a respectful approach to soft and hard tissues before reconstruction or implant placement.

What are the technical characteristics of the 12.302.00 system?

The Benex II extraction system (reference 12.302.00) is distinguished by its mechanical design allowing for longitudinal force transmission. The kit relies on a mechanism of screws and traction cables that are inserted into the previously prepared root canal. This 'large model' version is adapted to the varied clinical requirements of general practice and specialized surgery. As a Helmut Zepf product, it benefits from the German manufacturing quality specific to Helmut Zepf Medizintechnik GmbH. This specific model is identified as a demonstration model, intended to illustrate the vertical extraction technique without alveolar trauma.

What are the contraindications for the use of this device?

Contraindications for using the Benex II system include clinical situations where anchoring the traction screw is impossible, notably in cases of roots that are too short, major internal or external root resorption, or extreme structural fragility of the tooth allowing no grip. Furthermore, the use of this instrument should be avoided in patients presenting general contraindications to oral surgery. As with any precision medical device, it is advisable to refer to the Helmut Zepf manufacturer's technical instructions to validate the feasibility of the extraction based on the patient's specific root anatomy.

What are the maintenance precautions for this non-resorbable equipment?

As a metallic and non-resorbable surgical instrumentation device, the Benex II system requires a strict protocol of cleaning, disinfection, and sterilization between each use, in accordance with directives on reusable medical devices. Practitioners must ensure they regularly inspect the condition of the traction cables and anchoring screws to prevent any risk of breakage or loss of effectiveness. Appropriate lubrication of the moving parts of the extraction mechanism may be necessary according to Helmut Zepf Medizintechnik GmbH recommendations to ensure the fluidity of the axial traction movement during interventions.

Who is the manufacturer and what standards are respected?

The Benex II extraction system is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-quality dental and surgical instrumentation. Although the specific regulatory class and CE marking are not detailed in this technical sheet, Helmut Zepf products are generally designed according to the rigorous manufacturing standards of the German medical industry. For any precise information regarding certifications, applied ISO standards, or MDR regulatory compliance details, it is imperative to consult the official documentation provided by the manufacturer or to contact the Delynov technical service.
