What is the BENEX II - Dr. Benno Syfrig system from Helmut Zepf?

The BENEX II, designed in collaboration with Dr. Benno Syfrig and manufactured by Helmut Zepf Medizintechnik GmbH, is a Class I medical device dedicated to high-precision dental extraction. This system is specifically developed to allow for the controlled extraction of single-rooted teeth as well as root fragments. Its design primarily aims at the preservation of soft tissues and surrounding bone structures, a crucial aspect in pre-implant surgery. The kit referenced under code 12.303.00 at Delynov constitutes an advanced technical solution for healthcare professionals demanding reliable and durable equipment for their daily interventions in the dental office.

What are the clinical indications for the BENEX II?

The BENEX II system from the brand Helmut Zepf is indicated for the controlled extraction of single-rooted roots and radicular fragments, particularly when the conservation of tissue integrity is required. Another major indication is extrusion, allowing for the atraumatic repositioning of a dental root out of its socket before splint fixation. For multi-rooted dental roots, the manufacturer's protocol stipulates that they must imperatively be separated before proceeding with the extraction. This device is essential for practitioners wishing to minimize alveolar trauma during complex avulsions or implant site preparations.

What are the technical characteristics of device 12.303.00?

The BENEX II device relies on a rigorous technical protocol. It involves the use of diamond-coated twist drills for axial drilling in the center of the root fragment, at a depth of approximately 7 mm into the hard tissues. The manufacturer Helmut Zepf recommends a rotation speed between 500 and 700 r.p.m. with indispensable water cooling. The system uses extraction screws (short or long) fixed via a dedicated screwing device. The extractor is then positioned on the crowns of adjacent teeth, using a round and pivoting support piece oriented in a vestibular direction for optimal visibility. Traction is exerted by a cable connected to a deflection pulley and a traction carriage.

What are the contraindications and limitations for the use of this system?

The use of the BENEX II is strictly reserved for qualified healthcare professionals. A direct contraindication concerns non-separated multi-rooted teeth: these must undergo prior separation to be extracted individually. The intervention systematically requires appropriate anesthesia. The manufacturer also specifies that drilling must not exceed the necessary depth in hard tissues (approximately 7 mm) and must avoid transverse movements during the mobilization phase. Failure to comply with the recommended rotation speeds for the various components (up to 3000 r.p.m. depending on the drill reference) can compromise the safety of the surgical act.

What are the precautions for use and processing of the equipment?

As a Class I device intended for professional use, the BENEX II from Helmut Zepf requires expert handling. During drilling, a back-and-forth movement (in/out) is recommended to facilitate the removal of chips, especially in the case of deep drilling. Before the extraction itself, the periodontal fibers (Sharpey's fibers) must be severed in the sulcus using a periotome. For long and strong roots, an axial mobilization phase of 30 seconds with an elevator or a twister is necessary. Regarding durability, although there is no defined maximum limit for processing cycles, the condition of the equipment must be checked regularly by the practitioner.

Who is the manufacturer of the BENEX II and what standards are respected?

The BENEX II is manufactured by Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. As a Class I medical device, it meets the regulatory requirements in force for dental surgical instruments. The manufacturer ensures the traceability and quality of this high-end extraction system, widely recognized in the community of dental surgeons and implantologists. Each component, such as the drill or extraction screws, follows strict manufacturing standards to guarantee consistent performance during controlled extraction and atraumatic extrusion procedures.

What is the Benex II system from Helmut Zepf?

The BENEX II, developed by Dr. Benno Syfrig and manufactured by Helmut Zepf Medizintechnik GmbH, is a high-precision root extraction system. Referenced under code 12.303.00, this Class I device is designed to perform dental extractions via axial traction. Unlike conventional methods using transverse movements, this root extraction kit relies on a cable and deflection pulley mechanism. It allows for the removal of root fragments without damaging the alveolar bone or surrounding soft tissues. All Helmut Zepf instrumentation is developed to meet the requirements of modern oral surgery, offering a reliable solution for managing complex or fractured roots.

What are the clinical indications for this dental extractor?

The use of Benex II is indicated for the controlled extraction of roots from single-rooted teeth as well as root fragments. It is particularly recommended in situations where preserving the integrity of soft tissues and bone structures is a priority, notably for immediate implantation. For multi-rooted teeth, the protocol requires that roots be separated before using the extractor. Another major clinical application is extrusion, consisting of the atraumatic repositioning of a root out of its socket for subsequent splint fixation. This system guarantees a targeted intervention by minimizing periradicular trauma during avulsion.

What are the technical characteristics of the 12.303.00 system?

The Benex II system (reference 12.303.00) is distinguished by its specific operating mode. The technical protocol requires the use of a diamond-coated twist drill to create a 7mm deep housing in the hard tissues, with a recommended rotation speed between 500 and 700 r.p.m. (up to 3000 r.p.m. depending on the drill used). An extraction screw, short or long, is then inserted using a screwing device. The extractor itself is equipped with a round, pivoting support piece that is positioned on the crowns of adjacent teeth. Traction is exerted by a metallic cable connecting the screw to the instrument, ensuring a perfectly vertical removal of the fragment without lateral pressure on the alveolar walls.

What are the contraindications for using the Benex II?

Although the manufacturer Helmut Zepf Medizintechnik GmbH does not list specific medical contraindications in the provided documentation, use of the device is subject to strict adherence to the surgical protocol. It is imperative not to perform transverse movements with elevators during the preliminary mobilization phase, so as not to compromise the integrity of the socket. Furthermore, long and strong roots must be axially mobilized for approximately 30 seconds before final traction. Failure to separate roots for multi-rooted teeth constitutes a major procedural error, as each root must be extracted individually to guarantee the system's effectiveness.

What precautions should be taken when using the instrumentation?

To ensure the safety and efficacy of extraction with the Benex II, several precautions must be observed. Drilling with the diamond drill must be performed under water cooling to avoid thermal necrosis of the bone. A back-and-forth (in/out) movement is necessary during deep drilling to facilitate the removal of dentin chips. The drilling axis must be as central as possible relative to the root fragment. When placing the extractor, the opening of the pivoting support piece must be oriented in the vestibular direction to maintain a direct view of the extraction screw. These technical steps ensure the longevity of the Helmut Zepf instrumentation and the clinical success of the atraumatic extraction.

Who is the manufacturer and what standards are met?

The Benex II system is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. This medical device is classified as Class I according to current regulations. As a Helmut Zepf product, it benefits from the company's expertise in designing high-precision surgical instruments. Reference 12.303.00 is specifically associated with the research of Dr. Benno Syfrig, guaranteeing a validated clinical approach to root extraction. Compliance with standard cleaning and sterilization protocols for Class I instruments is necessary to maintain patient safety and equipment performance within the dental practice.
