Tunneling Instrument 4 - Helmut ZEPF (46.040.04) - Delynov becomes Tunneling Instrument 4 Helmut ZEPF for dental surgery.

What is the Helmut Zepf tunneling instrument 4?

The tunneling instrument 4, referenced under code 46.040.04 by the manufacturer Helmut Zepf Medizintechnik GmbH, is a manual dental instrument specifically developed for periodontal plastic surgery procedures. Manufactured from high-quality medical stainless steel, this tool is designed for delicate soft tissue preparation. Its structure allows for intervention in restricted anatomical areas to perform tunneling techniques aimed at treating gingival recessions or increasing the volume of keratinized mucosa. As a Class I device, it meets safety and performance requirements for professional use in dental practices or operating rooms.

What are the clinical indications for this instrument?

This instrument is primarily indicated for minimally invasive muco-gingival surgery techniques, notably the tunnel technique. It is used by practitioners for the precise detachment of full-thickness or partial-thickness flaps without resorting to releasing incisions. Its use is common during connective tissue grafts or for the placement of acellular dermal matrices. The clinical objective is to create a recipient space for the graft while maintaining optimal vascularization of the overlying tissues. It can also be used as a periosteal elevator during certain phases of implant surgery to release peri-implant tissues in a controlled manner.

What are the technical characteristics of instrument 46.040.04?

The Helmut Zepf tunneling instrument 4 is distinguished by its medical stainless steel composition, ensuring corrosion resistance and durability during sterilization cycles. Its ergonomic design is adapted to micro-surgery requirements, offering a stable grip for high-precision movements. The geometry of its active ends is specifically studied to insert under the marginal gingiva and progress along the tooth root or alveolar ridge without lacerating the tissues. This device is delivered non-sterile and must undergo a complete reprocessing protocol before its first use and after each clinical intervention.

What are the contraindications for using this instrument?

The main contraindication related to the use of this Helmut Zepf tunneling instrument is the patient's known hypersensitivity or intolerance to metals, and specifically to medical stainless steel components. A hypersensitivity reaction may be triggered upon contact between the instrument and the patient's tissues. The manufacturer states that if such a reaction occurs during the intervention, the procedure must be stopped immediately and necessary medical measures must be taken. It is therefore recommended to evaluate the patient's allergic history before any surgical manipulation with this manual device.

What are the maintenance and sterilization precautions?

All Helmut Zepf instruments must be cleaned, disinfected, and sterilized before their first use and after each subsequent use. It is imperative to perform complete cleaning to remove all biological residue before the sterilization cycle. The practitioner must visually inspect each product before use to detect any visible damage or wear, such as cracks, breaks, or defects on the cutting edges. The use of damaged or worn products is strictly prohibited. Due to the design and materials used, there is no defined maximum limit for the number of processing cycles, as long as the functional integrity of the instrument is preserved.

Who is the manufacturer and what standards are respected?

The instrument is manufactured by Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. This manufacturer is recognized for its expertise in the design of dental surgical instruments. The product is classified as a Class I medical device according to current regulations. It is exclusively reserved for use by qualified healthcare professionals. Compliance with the safety and usage instructions provided by Helmut Zepf is essential to guarantee patient safety and instrument longevity. Compatibility with other products used during surgery must also be verified beforehand by the practitioner.
