Trepan. Internal Diameter 5.00 MM - Helmut Zepf (08.912.50) - Delynov

What is the Helmut Zepf 5.00 mm trepan?

The Helmut Zepf trepan (reference 08.912.50) is a precision rotary instrument designed for oral bone surgery. This dental trepan features an internal diameter of 5.00 mm, allowing for the extraction of bone cores of specific dimensions. Manufactured in medical stainless steel by Helmut Zepf Medizintechnik GmbH, it is a hollow drill equipped with sharp cutting edges at its distal end. This instrument is delivered non-sterile and requires a complete cleaning and sterilization protocol before its first use in the office or operating room. Its robust structure is designed to meet the demands of implant and periodontal surgery procedures.

What are the clinical indications for this dental trepan?

This 5mm dental trepan is primarily indicated for harvesting autogenous bone in the form of cylinders, a preferred technique for localized bone grafts. In implantology, it is used to prepare the recipient site or to remove a defective or ankylosed implant while maximizing the preservation of the surrounding bone capital. The 5mm trepan drill can also be used for the excision of complex residual roots or for performing bone biopsies for diagnostic purposes. Its use is strictly reserved for healthcare professionals trained in oral surgery techniques, ensuring safe and effective handling during cortical and cancellous drilling procedures.

What are the technical characteristics of the 08.912.50 trepan?

The Helmut Zepf trepan is characterized by a precise internal diameter of 5.00 mm, a critical dimension for calibrating bone harvests. It is designed in high-quality medical stainless steel, ensuring the necessary resistance when drilling hard tissues. Reference 08.912.50 indicates a design optimized for bone debris evacuation and a clean cut. As a Class I device, it meets the fundamental regulatory requirements for manual and rotary dental instruments. Its design allows for repeated reprocessing (cleaning, disinfection, and sterilization), although it is imperative to check for the absence of visible damage, such as cracks or wear on the cutting edges, before each procedure.

What are the contraindications for using this instrument?

The main contraindication mentioned by the manufacturer Helmut Zepf Medizintechnik GmbH concerns known hypersensitivity or intolerance to metals, specifically medical stainless steel. If an allergic reaction or intolerance manifests in the patient upon contact with the instrument, the surgical procedure must be immediately interrupted and appropriate medical measures must be initiated. Additionally, the use of this trepan is prohibited if the instrument shows visible defects, breaks, or dulling of the sharp edges, as this could compromise patient safety and the effectiveness of the surgical act. It must not be used on patients with general contraindications to oral surgery.

What are the maintenance and sterilization precautions?

As the trepan is delivered non-sterile, a complete reprocessing cycle is mandatory before the first use and after each subsequent use. This includes thorough cleaning, disinfection, and validated sterilization. The manufacturer specifies that due to the design and materials of the instrument, there is no defined maximum limit for processing cycles, provided the physical integrity of the tool is preserved. The practitioner must imperatively inspect the trepan before each use to detect any trace of corrosion, crack, or deformation. The use of damaged or worn products is strictly prohibited to guarantee drilling precision and avoid any risk of instrument fracture during the operation.

Who is the manufacturer and what standards are respected?

The trepan is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. This medical device belongs to Class I according to current regulations. The manufacturer ensures the compliance of its products with safety and performance standards applicable to dental instruments. Helmut Zepf imposes strict quality control protocols during the production of its stainless steel instruments. As a Class I device, it is designed to meet the requirements of the most demanding healthcare professionals in oral surgery and implantology, ensuring compatibility with hospital and dental office standards for reprocessing and clinical use.
