Surgical expansion screw, 2.0 x 3.0 mm - Helmut Zepf (47.565.06) - Delynov

What is the Helmut Zepf 2,0 x 3,0 mm expansion screw?

The Helmut Zepf expansion screw, referenced under code 47.565.06, is a miniature osteosynthesis device used in oral surgery. This component is specifically dimensioned with a diameter of 2,0 mm and a length of 3,0 mm. Its structure is designed to offer stable mechanical holding within the bone tissue during reconstruction phases. As a product from the Helmut Zepf Medizintechnik GmbH catalog, this screw meets the manufacturing requirements of precision instrumentation. It is integrated into guided bone regeneration (GBR) protocols where the fixation of substitute materials or barriers is necessary to ensure the success of bone augmentation before or during implant placement.

What are the clinical indications for this dental surgical screw?

This dental surgical screw is primarily indicated for the stabilization of autogenous bone blocks or protective membranes during alveolar reconstruction surgeries. Its small size of 3,0 mm in length makes it particularly useful in areas where residual bone volume is limited or when the available space between adjacent tooth roots is restricted. Practitioners use it to prevent any micromovement of the graft, an essential factor for revascularization and osseointegration of the filling material. It finds its application in horizontal or vertical ridge augmentations, as well as in the treatment of complex peri-implant bone defects requiring rigid fixation.

What are the technical characteristics of reference 47.565.06?

Technical reference 47.565.06 corresponds to an expansion screw with dimensions of 2,0 x 3,0 mm. These geometric specifications are crucial for the choice of the pilot drill and the appropriate screwdriver during the intervention. The thread design is optimized to guarantee immediate primary grip in the cortical bone while respecting the integrity of the surrounding tissues. Manufactured by Helmut Zepf Medizintechnik GmbH, this screw benefits from high-precision machining guaranteeing perfect compatibility with placement instruments from the same range. Its compactness allows for easy handling in difficult-to-access surgical sites, thus offering a reliable fixation solution for implant and periodontal surgery protocols.

What are the contraindications for the use of this device?

Contraindications for the use of this expansion screw include clinical situations where bone quality is insufficient to guarantee primary stability of the device. Generally, use is discouraged in patients presenting systemic contraindications to oral surgery, such as uncontrolled coagulation disorders, severe metabolic bone pathologies, or an active infection at the surgical site. Insufficient oral hygiene or heavy smoking can also compromise GBR results and constitute relative contraindications. It is the surgeon's responsibility to evaluate the benefit-risk ratio based on the patient's overall health status and the nature of the site to be treated.

What precautions should be taken for this non-resorbable device?

As a non-resorbable metallic device, this Helmut Zepf expansion screw requires rigorous planning regarding its removal or long-term maintenance. In the majority of bone grafting protocols, the screw must be removed after the healing and consolidation phase of the graft, generally during the implant placement step or aesthetic finalization. The practitioner must ensure that the screw head is correctly covered by soft tissue to avoid any premature exposure, which could lead to infection of the surgical site. Post-operative radiographic follow-up is recommended to verify the stability of the device and the evolution of bone regeneration around the fixed area.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a company recognized in the surgical and dental instrumentation sector for its technical expertise. Although the specific regulatory class and CE marking are not detailed in the current source data, Helmut Zepf products are generally designed according to the rigorous quality standards applicable to medical devices in Europe. To obtain precise information on certifications, respected ISO standards, or to consult the declaration of conformity, it is imperative to refer to the instructions for use provided with the product or to contact the manufacturer directly. Compliance with the sterilization and use protocols recommended by Helmut Zepf is essential to guarantee patient safety.
