Helmut Zepf (12.300.35) - Delynov - Lot of 2 Forest Benex 2.1 mm Diameter

What is the 2.1 mm diameter Benex drill set from Helmut Zepf?

The 2.1 mm diameter Benex drill set, referenced under code 12.300.35, is a set of two rotary instruments designed by the manufacturer Helmut Zepf Medizintechnik GmbH. These drills are specific components of the Benex system, intended for initial canal preparation during root extraction procedures. They feature a diamond helical structure allowing for precise penetration into hard tissues. This device belongs to the category of dental surgery consumables and is classified as a Class I medical device. Their design is optimized to guarantee centered axial drilling, which is essential for the subsequent placement of the extraction system's traction screws.

What are the clinical indications for this benex drill?

The use of this benex drill is indicated for the controlled extraction of single-rooted tooth roots as well as for the removal of root fragments. It is particularly recommended in clinical situations where the preservation of soft tissues and surrounding bone structures is a priority, such as in pre-implant surgery. Another major indication concerns extrusion, i.e., the atraumatic repositioning of a root out of its socket for splint fixation. For multi-rooted teeth, the indication specifies that the roots must imperatively be separated beforehand to allow for the individual extraction of each fragment with the Helmut Zepf Benex system.

What are the technical characteristics and drilling recommendations?

The Benex 12.300.35 drill has precise technical specifications to ensure the safety of the surgical procedure. The manufacturer Helmut Zepf recommends a maximum rotation speed of 2200 r.p.m. (revolutions per minute), although the recommended range is generally between 500 and 700 r.p.m. for optimal control. Drilling must be performed with constant water cooling to avoid any thermal overheating of the hard tissues. The required drilling depth in solid tissues is approximately 7 mm; deeper drilling is not necessary. To facilitate the removal of chips during deep drilling, it is advisable to perform back-and-forth movements (in/out).

What are the contraindications for the use of these instruments?

The main contraindications concern the anatomical configuration of the roots. Direct use on multi-rooted tooth roots without prior separation is prohibited; these must be sectioned to be treated as single-rooted entities. Furthermore, drilling must not deviate from the central axis of the root fragment to avoid any lateral perforation that would compromise the stability of the extraction screw. The use of these drills must be performed under adequate anesthesia. Finally, as specified by the manufacturer Helmut Zepf, the use of these devices is strictly reserved for qualified healthcare professionals mastering atraumatic extraction protocols.

What are the maintenance and processing precautions for the drills?

Although classified as consumables (CONSO), these drills are subject to processing cycles. The manufacturer Helmut Zepf Medizintechnik GmbH indicates that there can be no defined maximum limit for the intended use, as the number of achievable processing cycles depends on the maintenance and wear observed by the professional. Drills must be inspected before each use to verify their integrity and cutting power. Rigorous cleaning and appropriate sterilization are essential between each patient. In the event of a loss of performance during helical drilling, the drill must be replaced to guarantee the precision of the surgical gesture and avoid any excessive mechanical stress on the root.

Who is the manufacturer and what standards are respected?

These drills are manufactured by Helmut Zepf Medizintechnik GmbH, a company located in Seitingen-Oberflacht, Germany, recognized for its expertise in surgical instrumentation. This product is a Class I medical device, complying with the regulatory requirements in force for this category of instruments. The manufacturer ensures traceability and manufacturing quality according to dental surgery standards. As a Class I device, it meets safety and performance standards for root extraction and extrusion. Each lot, such as reference 12.300.35 distributed by Delynov, is subject to the rigorous controls of the Helmut Zepf quality management system.
