Retrograde Instrument - Helmut Zepf (24.725.74) - Delynov

What is the Helmut Zepf retrograde instrument (24.725.74)?

The Helmut Zepf retrograde instrument, referenced under code 24.725.74, is a manual device specifically developed for endodontic micro-surgery. Manufactured in medical stainless steel by Helmut Zepf Medizintechnik GmbH, this tool belongs to the category of micro-surgery instruments. Its design allows for precise manipulation within the restricted environment of the oral cavity, particularly during interventions on the root apex. As a surgical micro-instrument, it meets the durability and resistance requirements necessary for repeated clinical procedures while maintaining a structural fineness adapted to retro-preparation protocols.

What are the clinical indications for this surgical endodontic instrument?

This instrument is indicated for endodontic surgery procedures, notably during apical resection or retrograde obturation. It is used by dental surgeons and endodontic specialists to manipulate filling materials or to prepare the root canal via the apical route. Its use is relevant when conventional orthograde endodontic treatment has failed or is impossible. This type of surgical endodontic instrument allows for high-precision intervention on root structures, minimizing impact on surrounding tissues while ensuring the apical seal necessary for therapeutic success.

What are the technical characteristics of reference 24.725.74?

Technical reference 24.725.74 corresponds to an endodontic micro-surgery instrument manufactured by Helmut Zepf Medizintechnik GmbH. It is designed in high-quality medical stainless steel, guaranteeing corrosion resistance during sterilization cycles. This device is classified as a Class I instrument according to current regulations. It is delivered non-sterile and requires a complete protocol of cleaning, disinfection, and sterilization before its first use and after each subsequent use. Its morphology is optimized to adapt to restricted spaces, perfectly complementing the use of a retrograde plugger or an endo micro-mirror when examining root surfaces.

What are the contraindications for using this instrument?

The main contraindication mentioned by the manufacturer Helmut Zepf concerns known hypersensitivity or intolerance of the patient to metals, specifically to the medical stainless steel used for the instrument's manufacture. An allergic or hypersensitivity reaction may be triggered upon contact with tissues. If such a reaction occurs during the intervention, the procedure must be immediately stopped and appropriate medical measures must be taken. It is therefore recommended to check the patient's allergic history before any use of this endo retrograde instrument.

What are the maintenance and reprocessing precautions?

Helmut Zepf products are delivered non-sterile and must undergo a complete reprocessing cycle before use. This includes cleaning, disinfection, and sterilization. Before each use, the practitioner must visually inspect the instrument to detect any damage or visible wear, such as cracks, breaks, or defects on the cutting edges. The use of damaged or worn products is strictly prohibited. Due to its design and the materials used, there is no defined maximum limit for treatment cycles, but compatibility with other cleaning products must be verified beforehand by the healthcare professional.

Who is the manufacturer and what standards are respected?

The official manufacturer of this instrument is the company Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. This medical device complies with the regulations for Class I devices (Class Ir according to reprocessing specifications). The manufacturer imposes strict safety and use protocols, emphasizing that the use of this instrument is exclusively reserved for qualified healthcare professionals. Compliance with cleaning and sterilization instructions is crucial to guarantee patient safety and the longevity of this endo retrograde instrument within the dental practice.
