Metal Rule 20 cm - Helmut Zepf (48.666.20) - Delynov

What is the 20 cm metal ruler - Helmut Zepf?

The 20 cm metal ruler developed by Helmut Zepf is a manual measuring instrument designed specifically for the clinical environment. Manufactured from medical stainless steel, this dental graduated ruler features a rigid and durable structure adapted to the requirements of surgical instrumentation. It provides practitioners with a reliable metric reference directly on the surgical field. Its metal design ensures resistance to repeated sterilization cycles while maintaining optimal readability of the graduations. This instrument belongs to the category of reusable consumables (CONSO) and meets the quality standards of German manufacturing.

What are the clinical indications for this instrument?

This surgical metal ruler is indicated for all procedures requiring precise dimensional evaluation in the mouth or on related medical devices. In implantology, it is used to measure the available mesio-distal space before placing an implant or to verify the length of drills and abutments. In periodontal or maxillofacial surgery, it allows for the calibration of dimensions for flaps or connective tissue grafts. Its use also extends to verifying mouth opening or measuring soft tissue thickness, providing indispensable assistance for following surgical protocols based on strict anatomical measurements.

What are the technical characteristics of the 48.666.20 ruler?

The technical reference 48.666.20 corresponds to a ruler with a total length of 20 cm. It is designed by Helmut Zepf Medizintechnik GmbH in high-quality stainless steel, ensuring biocompatibility during temporary contact with mucous membranes. The ruler features precise graduations allowing for millimeter measurements. Its finish is designed to limit reflections under the scialytic lighting of the office, thus facilitating rapid reading during the surgical act. As a manual instrument, it contains no electronic mechanism, which simplifies its maintenance and guarantees constant reliability without the risk of failure or decalibration related to the wear of internal components.

What are the contraindications for the use of this ruler?

The main medical contraindication mentioned by the manufacturer Helmut Zepf concerns patients with a known hypersensitivity or intolerance to metals, particularly medical stainless steel. A hypersensitivity reaction can be triggered upon contact between the instrument and the patient's tissues. If such a reaction occurs, the procedure must be immediately interrupted and necessary clinical measures must be taken. Apart from this specific sensitivity to metallic components, there are no contraindications related to the measuring function itself, provided the instrument is used according to its intended purpose by a qualified healthcare professional.

What are the maintenance and reprocessing precautions?

Helmut Zepf products are delivered non-sterile and must imperatively be cleaned, disinfected, and sterilized before the first use, and then between each patient. It is crucial to visually inspect the ruler before each use to detect any potential damage or signs of wear such as cracks, breaks, or altered edges. The use of damaged products is strictly prohibited. Due to its robust stainless steel design, there is no defined maximum limit for sterilization cycles, but the lifespan of the instrument depends on the absence of visible defects. Compliance with standard cleaning protocols for dental instrumentation is necessary to ensure the safety of the patient and the practitioner.

Who is the manufacturer and what standards are respected?

The official manufacturer of this instrument is the company Helmut Zepf Medizintechnik GmbH, located in Germany. This medical device is classified as Class I according to current regulations. The manufacturer applies rigorous control processes in accordance with the requirements for manual dental instruments. Compliance with safety and usage instructions is essential to ensure the conformity of the device throughout its life cycle. As a Class I instrument, it meets the safety and performance standards applicable to non-invasive or invasive devices for temporary use, thus ensuring consistent quality for demanding dental surgeons and implantologists.
