Approximal desmotome with 3mm distal curvature, single end, M4x0.5 - Helmut Zepf (17.045.04) - Delynov

What is the Helmut Zepf 17.045.04 approximal desmotome?

The approximal desmotome referenced 17.045.04 by Helmut Zepf is a specialized surgical instrument used in periodontology and oral surgery. This model is distinguished by a single-ended tip featuring a 3 mm distal curvature. It is designed to integrate into the Helmut Zepf brand system using an M4x0.5 connection, allowing the insert to be attached to a compatible handle. Its structure is optimized to insert into the periodontal space in order to break the tooth's ligament attachments. This instrument is an essential component for practitioners performing minimally invasive extractions, aiming to preserve the integrity of the alveolar walls.

What are the clinical indications for this instrument?

This device is primarily indicated during the initial phases of dental avulsion. In oral and implant surgery, the approximal desmotome allows for syndesmotomy, consisting of separating the marginal gingiva and sectioning the alveolar-dental ligament. Its configuration with a 3 mm distal curvature makes it particularly effective for treating approximal surfaces, which are often difficult to access with straight instruments. By releasing the tooth from its ligament attachments without exerting excessive lateral pressure on the alveolar bone, this instrument helps prevent fractures of the bone plate, a crucial step for subsequent implant placement.

What are the technical characteristics of this desmotome?

The Helmut Zepf desmotome (reference 17.045.04) features precise technical specifications to meet micro-surgery requirements. It has a single working part (one tip) with a distal curvature calibrated at 3 mm. This dimension allows for precise insertion into the sulcus and controlled progression along the root. The M4x0.5 thread ensures rigid and secure fixation on instrument handles from the Helmut Zepf range. Although material details are not specified in the source data, this type of insert is traditionally designed to withstand repeated sterilization cycles in a clinical environment.

What are the contraindications for the use of this device?

Contraindications for the use of the approximal desmotome are related to the general clinical conditions of oral surgery. Its use is discouraged on non-targeted anatomical structures or if the practitioner does not have sufficient visibility of the operative field. As with any metal instrument, a known hypersensitivity to the alloy components (generally stainless steels) constitutes a contraindication. The instrument should not be used if the working tip shows signs of wear, deformation, or corrosion, as this could compromise the precision of the surgical gesture or lead to tissue complications.

What are the maintenance and handling precautions?

As a non-resorbable and reusable instrument, the Helmut Zepf desmotome requires a strict decontamination, cleaning, and sterilization protocol after each use. Practitioners must ensure that the M4x0.5 thread is perfectly clean before mounting on the handle to guarantee optimal stability. The thinness of the 3 mm tip requires careful handling to avoid any blunting or breakage during accidental contact with hard surfaces. It is recommended to follow the specific instructions from the manufacturer Helmut Zepf Medizintechnik GmbH regarding autoclaving parameters and the use of non-corrosive cleaning solutions.

Who is the manufacturer and what standards are respected?

This device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the dental and surgical instrumentation sector. The Helmut Zepf brand is synonymous with technical precision in the field of oral surgery. Regarding specific standards and certifications, such as the regulatory class or CE marking, this information is not detailed in the current source documentation. It is the responsibility of the healthcare professional to refer to the product labeling and the instructions for use provided by the manufacturer to verify compliance with current regulatory requirements, notably the European Medical Device Regulation (MDR).
