Forest for Dental Implant VIS BENEX Ø 1.6 mm, length 16 mm - Helmut Zepf (12.300.70) - Delynov

What is the root extraction screw for BENEX system Ø 1.6 mm?

The root extraction screw for BENEX system is a precision surgical device manufactured by Helmut Zepf Medizintechnik GmbH. This specific model features a diameter of 1.6 mm and a length of 16 mm, delivered in a set of 2 units under reference 12.300.70. This instrument is designed to integrate perfectly with the Benex screw kit, offering a robust solution for anchoring into the hard tissues of the root. Its structure is optimized to withstand the axial traction forces required during complex avulsion procedures, ensuring a stable connection between the root fragment and the extractor mechanism.

What are the clinical indications for these extraction screws?

These extraction screws are primarily indicated for the controlled extraction of single-rooted teeth roots and root fragments. They are particularly recommended in clinical situations where the preservation of soft tissues and surrounding bone structures is a priority, such as during pre-implant surgeries. Another major indication concerns extrusion, which is the atraumatic repositioning of a dental root out of its socket for subsequent splint fixation. For multi-rooted teeth, the use of the dental extraction screw requires prior separation of the roots to allow for individual and secure mobilization.

What are the technical characteristics of the Benex 1.6 mm screw?

The benex 1 6 screw (reference 12.300.70) possesses rigorous technical characteristics to meet the requirements of oral surgery. It features a diameter of 1.6 mm and a total length of 16 mm. Its use requires a precise drilling protocol using a diamond twist drill, ideally centered in the axis of the root fragment. The manufacturer Helmut Zepf recommends drilling approximately 7 mm deep into solid hard tissues, accompanied by water cooling. Screwing is then performed using the dedicated device, allowing the extractor's traction cable to anchor securely to initiate the axial exit movement.

What are the contraindications for the use of this device?

The direct use of these screws on multi-rooted teeth without prior separation constitutes the main technical contraindication. Roots must imperatively be divided to be extracted one by one. Furthermore, use is strictly reserved for qualified healthcare professionals mastering the Benex protocol. It is also necessary to perform adequate anesthesia and section the periodontal fibers (Sharpey's fibers) in the sulcus using a periotome before any tensioning. Failure to respect the drilling axis or insufficient depth in the hard tissues can compromise the stability of the screw during traction.

What are the precautions for use and processing?

As a Class I medical device, these Helmut Zepf extraction screws are intended to be used according to processing cycles whose maximum limit is not defined, but must be determined by the professional according to observed wear. Before extraction, long and strong roots must be mobilized or luxated in the axial direction for 30 seconds using an elevator or a twister, without transverse movements to avoid root fracture. During preparatory drilling, a speed of 500 to 700 r.p.m. is recommended. It is crucial to maintain an in/out movement during deep drilling to ensure effective removal of dentin chips.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. This product is a Class I medical device, meeting the regulatory requirements in force for non-invasive or invasive surgical instruments for temporary use. As a recognized manufacturer in the field of dental instrumentation, Helmut Zepf guarantees a design adapted to sterilization and reuse protocols in dental practices. Each batch of atraumatic extraction screws is tracked according to strict quality standards, ensuring practitioners constant reliability during root avulsion interventions.
