Ouvre-Couronnes - Crown Opener - Helmut Zepf (19.279.00) - Delynov

What is the Helmut Zepf 19.279.00 crown spreader?

The Helmut Zepf crown spreader, referenced under code 19.279.00, is a precision manual instrument intended for dental practices. It is manufactured from high-quality medical stainless steel, ensuring the structural resistance necessary for the leverage forces applied during prosthetic removal. As an instrument from the Helmut Zepf brand, this device is designed to meet the requirements of modern dental surgery. Its structure is specifically adapted to fit into the sectioning grooves previously made on crowns or bridges, thus allowing efficient separation of metallic or ceramic components.

What are the clinical indications for this instrument?

This crown removal instrument is indicated for all procedures requiring the removal of fixed crowns or bridges. In clinical practice, it is used after the practitioner has sectioned the prosthesis using an appropriate bur. The dental crown spreader intervenes to spread the crown walls and break the cement or adhesive seal, thus facilitating the extraction of the coping without excessively damaging the underlying preparation. Its use is strictly reserved for qualified healthcare professionals working in odontology, prosthetics, or oral surgery.

What are the technical characteristics of the 19.279.00 crown spreader?

The Helmut Zepf 19.279.00 instrument is distinguished by its medical stainless steel composition, a material chosen for its biocompatibility and its ability to undergo repeated sterilization cycles. Being a Class I device, it meets the regulatory requirements for non-invasive manual instruments. Its ergonomic design allows for a firm grip, essential for transmitting the necessary force when spreading prosthetic metals. The manufacturer specifies that the number of achievable treatment cycles is not limited to a maximum, but depends on visible wear and the integrity of the instrument's cutting edges.

What are the contraindications for the use of this instrument?

The main contraindication mentioned by the manufacturer Helmut Zepf Medizintechnik GmbH concerns the patient's known hypersensitivity to metals. As the instrument is manufactured from medical stainless steel, contact may trigger an allergic reaction or intolerance in certain sensitive individuals. If such a hypersensitivity reaction occurs during the procedure, the procedure must be stopped immediately and necessary medical measures must be taken. It is therefore recommended to check the patient's allergic history before any use of this manual instrument in the mouth.

What are the maintenance and sterilization precautions?

All Helmut Zepf instruments must imperatively be cleaned, disinfected, and sterilized before their first use, as well as after each subsequent use. The reprocessing process must be complete to ensure clinical safety. Before each use, the practitioner must visually inspect the instrument to detect any potential damage or signs of wear, such as cracks, breaks, or defects on the cutting edges. It is formally forbidden to use a damaged or worn product. As the products are delivered non-sterile, strict compliance with current sterilization protocols is mandatory.

Who is the manufacturer and what standards are met?

This device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. This product is classified as a Class I medical device according to current regulations. The manufacturer ensures the compliance of its instruments with medical quality standards, notably through the use of surgical grade stainless steel. As a Helmut Zepf product, this crown spreader is subject to rigorous controls, and its maintenance is the responsibility of the healthcare professional who must validate compatibility with other products used during the procedure.
