BENEX Drills Ø 1.6 mm - Helmut Zepf (12.300.30) - Delynov

What is the Benex Ø 1.6 mm Helmut Zepf drill?

The Benex Ø 1.6 mm drill, referenced under code 12.300.30 by the manufacturer Helmut Zepf Medizintechnik GmbH, is a precision rotary instrument designed specifically for extraction surgery. This Benex system drill is intended to create a borehole in the hard tissues of the tooth root. Its structure allows for efficient removal of dentin chips, provided that a back-and-forth (in/out) movement is performed during deep drilling. It is an essential component for practitioners using the Benex extraction method, ensuring calibrated preparation before the placement of the traction screw.

What are the clinical indications for this root extraction drill?

The use of this root extraction drill is indicated for the controlled extraction of single-rooted teeth and 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. For multi-rooted teeth, the roots must imperatively be separated before using the drill. Additionally, this instrument is indicated for extrusion, allowing the atraumatic repositioning of a root out of its socket for subsequent splint fixation under anesthesia.

What are the technical characteristics of drill 12.300.30?

The dental Benex drill has a diameter of 1.6 mm. According to the recommendations of the manufacturer Helmut Zepf, drilling must be performed with water cooling to avoid tissue overheating. The recommended drilling depth in hard tissues is approximately 7 mm, as deeper drilling is not necessary for screw stability. Regarding rotary parameters, the recommended speed is between 500 and 700 revolutions per minute (r.p.m.), with a maximum safety limit set at 3000 r.p.m. for this specific reference. Drilling should be carried out as much as possible in the central axis of the root fragment.

What are the contraindications for the use of this device?

The main contraindications concern the state of the dental structures and the surgical protocol. This drill must not be used directly on multi-rooted teeth without prior root separation, as Benex extraction requires an individual approach per fragment. Prior axial mobilization or luxation for 30 seconds using an elevator or periotome is required for long and strong roots to break the periodontal fibers (Sharpey's fibers) before drilling. Failure to respect maximum rotation speeds or the absence of water cooling also constitute major technical contraindications.

What are the maintenance and processing precautions?

This medical device is reserved exclusively for healthcare professionals. Although the material allows for processing cycles, the manufacturer Helmut Zepf specifies that there can be no defined maximum limit for the intended use, as the achievable cycles depend on maintenance and observed wear. To guarantee optimal atraumatic extraction, the sharpness of the drill must be checked regularly. During use, an in/out movement is recommended to facilitate the evacuation of dentin debris, especially during drilling reaching the maximum depth of 7 mm, to avoid the instrument jamming in the canal.

Who is the manufacturer and what standards are respected?

The drill is manufactured by Helmut Zepf Medizintechnik GmbH, a company located in Seitingen-Oberflacht, Germany. This medical device belongs to Class I according to current regulations. As a product of the Helmut Zepf range, it meets the strict quality requirements imposed for dental surgery instruments. Compliance with sterilization protocols and rotation parameters (max 3000 r.p.m.) is essential to maintain the device's conformity during its use in dental practices or hospital environments. It integrates perfectly into the Benex atraumatic extraction protocol distributed by Delynov.
