Bone Expansion Surgical Kit with Expansion Screws - Helmut Zepf (47.565.00) - Delynov

What is the Helmut Zepf bone expansion surgical kit (47.565.00)?

The Helmut Zepf surgical bone expansion kit, referenced under code 47.565.00, is a set of specialized instruments designed for the manipulation and widening of maxillary or mandibular bone structures. This ridge expansion kit primarily consists of specific expansion screws that allow the practitioner to increase the width of the alveolar ridge through a process of condensation and mechanical spreading. Manufactured by Helmut Zepf Medizintechnik GmbH, this device is intended to prepare the recipient site before implant placement, particularly in clinical situations where horizontal bone volume is insufficient to guarantee primary implant stability.

What are the clinical indications for this expansion kit?

The use of this bone expansion kit is indicated in oral surgery and implantology when managing atrophied alveolar ridges with insufficient width. The kit is particularly useful for performing ridge expansions (split control) where the bone exhibits a certain elasticity, thus allowing for the creation of an adequate implant housing without loss of bone substance. It is used to optimize available bone volume, promote the condensation of cancellous bone, and improve the structural support necessary for implant integration. This Helmut Zepf equipment supports surgeons in immediate or delayed loading protocols depending on the bone quality encountered.

What are the technical characteristics of the expansion screws?

The Helmut Zepf 47.565.00 kit is distinguished by its high-precision technical expansion screws. These components are designed to offer optimal force transmission during manual or assisted screwing, allowing for progressive separation of the cortices without undesirable fractures. The thread geometry is designed to ensure stable progression in the bone tissue while minimizing thermal heating. Each instrument in the kit is developed according to the rigorous manufacturing standards of Helmut Zepf Medizintechnik GmbH, guaranteeing high mechanical resistance and compatibility with standard sterilization protocols in dental practices or operating rooms.

What are the contraindications for the use of this device?

Contraindications for the use of the Helmut Zepf bone expansion kit include clinical situations where the alveolar bone exhibits excessive mineralization or D1 type density, making mechanical expansion risky due to a lack of elasticity. Additionally, insufficient bone height or an active infection at the surgical site constitute major contraindications. As with any implant surgery procedure, uncontrolled systemic pathologies affecting bone metabolism or healing must be evaluated by the practitioner before the intervention. The manufacturer's technical instructions should be systematically consulted to identify specific restrictions related to the equipment.

What are the maintenance and handling precautions?

As this is a kit of non-resorbable and reusable surgical instruments, particular attention must be paid to the decontamination and sterilization protocol. After each use, the expansion screws and instruments of the Helmut Zepf kit must be cleaned manually or in a thermal disinfector to remove all organic residues, then sterilized in an autoclave according to the cycles recommended by the manufacturer. The practitioner must regularly inspect the surface condition of the screws and the threading to detect any signs of wear or deformation that could compromise the precision of the surgical gesture or patient safety during ridge expansion.

Who is the manufacturer and what standards are respected?

The surgical bone expansion kit (reference 47.565.00) is produced by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-performance dental and surgical instrumentation. Although specific details on the regulatory class or CE marking are not provided in this sheet, Helmut Zepf products are developed according to precision manufacturing processes. To obtain detailed information on compliance certifications, ISO standards met, or the specific CE marking for this expansion kit, it is imperative to consult the official technical documentation and the instructions for use provided by Helmut Zepf.
