Surgical expansion screw 2.8 x 4.0 mm - Helmut Zepf (47.565.08) - Delynov

What is the Helmut Zepf 2.8 x 4.0 mm surgical expansion screw?

The Helmut Zepf surgical expansion screw, referenced under code 47.565.08, is a specialized instrumentation device used in oral and implant surgery. This component is specifically designed for guided bone regeneration (GBR) protocols. Its structure features a diameter of 2.8 mm and a length of 4.0 mm, offering a solution adapted to restricted anatomical spaces or localized expansion needs. Manufactured by Helmut Zepf Medizintechnik GmbH, this device is part of a range of high-precision instruments intended for practitioners requiring constant reliability when manipulating hard tissues.

What are the clinical indications for this device?

The use of the 2.8 x 4.0 mm expansion screw is primarily indicated during implant site preparation phases, particularly in cases of narrow alveolar ridges. In oral surgery, it allows for controlled expansion of the bone, thus facilitating the subsequent insertion of implants or the placement of filling materials. It is particularly useful in GBR procedures where bone volume stability is critical. This Helmut Zepf device meets the requirements of dental surgeons and implantologists performing horizontal or vertical bone augmentations requiring precise mechanical anchoring or distraction.

What are the technical characteristics of reference 47.565.08?

The Helmut Zepf expansion screw (47.565.08) is defined by its rigorous dimensions of 2.8 mm in diameter and 4.0 mm in length. These technical specifications allow for targeted intervention on bone tissue with minimal footprint. The design of the Helmut Zepf Medizintechnik GmbH instrumentation ensures optimal force transmission during loading, guaranteeing high tactile control for the practitioner. Although specific material details are not mentioned, this type of device is traditionally designed to withstand the mechanical stresses encountered during penetration or spreading of bone cortices in a surgical environment.

What are the contraindications for the use of this expansion screw?

Contraindications for the use of the Helmut Zepf expansion screw are related to the clinical limits of oral surgery and the patient's physiological state. Use is prohibited in the presence of insufficient bone density to ensure screw stability or in case of active infections at the surgical site. Generally, contraindications include uncontrolled systemic pathologies affecting bone metabolism or healing, such as severe osteoporosis or the aftermath of radiotherapy. It is the surgeon's responsibility to evaluate the benefit/risk ratio based on the patient's anatomy and the quality of the recipient site before any implementation.

What are the precautions for use and maintenance?

As a non-resorbable device intended for a temporary mechanical or stabilization function, the Helmut Zepf expansion screw must be handled with appropriate instruments to avoid any deformation of the thread or screw head. The practitioner must ensure compliance with current sterilization protocols for reusable or single-use surgical instrumentation according to the manufacturer's specifications. Particular attention must be paid to the applied tightening torque to prevent any iatrogenic bone fracture or device breakage. After the intervention, clinical follow-up must confirm the absence of adverse inflammatory reactions around the material.

Who is the manufacturer and what standards are respected?

The 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 quality and precision in the field of oral surgery. Regarding regulatory certifications such as the device class or specific CE marking, this information is not explicitly detailed in the current technical documentation. It is imperative for the healthcare professional to systematically refer to the instructions for use and product labeling provided by Helmut Zepf to verify compliance with current MDR standards before any clinical use.
