Internal Diameter 8.0 MM TREPAN. DIAMETER - Helmut Zepf (08.910.10) - Delynov

What is the Helmut Zepf 8mm trepan?

The Helmut Zepf trepan (reference 08.910.10) is a specialized rotary surgical instrument designed by Helmut Zepf Medizintechnik GmbH. This device has an internal diameter of 8.0 mm, making it suitable for creating precise cylindrical bone blocks. As a Class IIa consumable, it is specifically developed for oral surgery and implant procedures. Its structure allows for autogenous bone harvesting or the removal of already integrated implants. This instrument is intended exclusively for healthcare professionals trained in bone surgery techniques.

What are the clinical indications for this trepan?

The primary indications for this 8mm trepan include harvesting cylindrical bone grafts from the jaw. These blocks can be transplanted directly to another surgical site or introduced into a bone mill for subsequent treatment for volume augmentation. Another major indication is the explantation of dental implants. The practitioner chooses the trepan diameter based on the size of the desired tissue block or the diameter of the implant to be removed, thus ensuring a procedure adapted to the patient's anatomy.

What are the technical characteristics and operating parameters?

The Helmut Zepf trepan reference 08.910.10 has an internal diameter of 8.0 mm. For optimal use when obtaining bone blocks, the manufacturer recommends attaching the instrument to a contra-angle and setting the motor to a speed between 800 rpm and a maximum defined by the device. For explantation, the recommended speed is between 800 rpm and 1000 rpm maximum. Drilling or milling must be performed with continuous insertion and withdrawal movements. Abundant irrigation with sterile physiological saline solution is imperative, either manually or via the contra-angle's cooling system.

What are the contraindications for the use of this instrument?

According to the data provided by the manufacturer Helmut Zepf Medizintechnik GmbH, the use of the trepan must follow strict protocols to avoid any incidents. Excessive pressure must never be applied during treatment. A critical instruction is not to stop the motor while the trepan is inside the surgical cavity; stopping the motor in position could prevent the removal of the instrument or cause it to break. Although specific clinical contraindications related to the patient's health status are not listed, use is strictly reserved for qualified healthcare professionals.

What precautions should be taken for handling and durability?

To ensure the safety of the procedure and the longevity of the instrument, the drilling process must be accompanied by constant rinsing. Lack of sufficient irrigation can lead to tissue overheating. Regarding service life, the manufacturer indicates that there is no defined maximum limit for the intended use, but the achievable treatment cycles can be determined by the user based on observed wear. It is essential to check the integrity of the trepan before each procedure to prevent any risk of breakage during mechanical stress in the maxillary or mandibular bone.
