Trepan. Internal Diameter 6.0 MM - Helmut Zepf (08.910.08)

What is the Helmut Zepf 6.0 mm trepan?

The Helmut Zepf trepan (reference 08.910.08) is a precision rotary instrument designed for oral surgery. This 6mm trepan features a specific internal diameter of 6.0 mm, allowing for the creation of calibrated cylindrical bone blocks. Manufactured by Helmut Zepf Medizintechnik GmbH, this Class IIa medical device is intended to be mounted on a surgical contra-angle. Its structure is optimized for the circular cutting of hard tissues, offering practitioners a reliable solution for autogenous bone harvesting or implant removal. As a dental trepan bur, it meets the rigorous requirements of bone augmentation procedures and implantology reinterventions.

What are the clinical indications?

The clinical indications for this 6mm trepan cover two main areas of maxillofacial and implant surgery. Firstly, it is used to obtain cylindrical bone blocks from the jaw, which can be transplanted directly or processed in a bone mill for filling procedures. Secondly, this instrument is indicated for the explantation of implants already in place. The choice of trepan must imperatively be made according to the diameter of the desired bone tissue block or the diameter of the implant to be removed to ensure a precise intervention adapted to the patient's anatomy.

What are the technical characteristics and usage parameters?

This 6mm trepan drill must be used with a surgical motor set to a specific speed. To obtain bone blocks, the recommended speed is between 800 rpm and an unspecified maximum (depending on the device limits), while for implant explantation, the recommended speed range is between 800 rpm and 1000 rpm maximum. The instrument requires abundant and continuous irrigation with sterile physiological saline solution, either manually or via the contra-angle cooling system. The drilling process must be performed with constant in-and-out movements to avoid overheating or blockage.

What are the contraindications for use?

Although the technical text does not list specific systemic medical contraindications, the use of this Helmut Zepf trepan is subject to strict handling constraints. Excessive pressure during drilling or milling must be prohibited. It is also crucial not to stop the motor while the trepan is inside the surgical cavity. Failure to follow this instruction may prevent the removal of the instrument or, in the most serious cases, cause the trepan to break at the operative site, thus compromising the success of the intervention.

What are the precautions when handling the trepan?

When using this 6mm trepan from Helmut Zepf, the practitioner must ensure continuous insertion and extraction movements are maintained. This technique, combined with generous physiological rinsing, allows for the evacuation of bone debris and limits thermal elevation of the surrounding tissues. It is imperative to select the 6.0 mm internal diameter in total accordance with the clinical objective (graft size or implant diameter). Particular attention must be paid to the stability of the contra-angle to avoid any axial deviation that could damage adjacent anatomical structures or weaken the instrument.

Who is the manufacturer and what standards are respected?

The trepan (reference 08.910.08) is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. This medical device is classified as Class IIa according to current regulations, which attests to its compliance with safety and performance requirements for invasive surgical-type devices for short-term use. Compliance with cleaning, disinfection, and sterilization protocols is essential, in accordance with the instructions from the manufacturer Helmut Zepf, to ensure patient safety and the longevity of the instrument during each bone surgery procedure.
