Stainless steel cross-head screw, Ø 1mm, length 10mm, with identification cap - Helmut Zepf (47.573.10S) - Delynov

What is the Helmut Zepf 47.573.10S cruciform screw?

The Helmut Zepf cruciform screw, reference 47.573.10S, is a fixation device used in oral surgery for bone regeneration protocols. Manufactured in stainless steel by Helmut Zepf Medizintechnik GmbH, this 1mm surgical screw is distinguished by its robust structure and cruciform head, allowing for optimal torque transmission during insertion. It is equipped with a specific identification cap for quick recognition within the surgical tray. This equipment is primarily intended for the osteosynthesis of small fragments or the maintenance of non-resorbable membranes in the context of alveolar reconstructions.

What are the clinical indications for this osteosynthesis screw?

This 1mm osteosynthesis screw is indicated for the rigid fixation of autologous bone grafts or bone substitute blocks during GBR (Guided Bone Regeneration) procedures. In implantology and periodontal surgery, it ensures the primary stability necessary for bone consolidation by preventing micromovements of the graft. It can also be used to secure titanium meshes or reinforcement membranes. Its small size makes it particularly useful in areas where available bone volume is limited or when the proximity of adjacent tooth roots requires the use of small-diameter material.

What are the technical specifications of the dental surgery steel screw?

Technical specifications for this model include a shaft diameter of 1mm and a total length of 10mm. These precise dimensions allow for controlled penetration into cortical and cancellous bone. The stainless steel design guarantees high mechanical resistance, essential for withstanding shear stresses during the healing phase. The screw head features a cruciform recess compatible with Helmut Zepf range screwdrivers. The included identification cap helps maintain sterile organization and instantly identify the screw length among other osteosynthesis references.

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

Contraindications for the use of this steel osteosynthesis screw primarily include known allergies or hypersensitivities to stainless steel or its metallic components. Clinically, it should not be used in sites with active infection or insufficient vascularization to allow bone healing. Inadequate bone density may also compromise screw stability. It is the practitioner's responsibility to evaluate standard systemic contraindications related to oral surgery, such as uncontrolled coagulation disorders or metabolic pathologies interfering with bone metabolism.

What are the precautions related to the non-resorbable nature of steel?

As a stainless steel device, this screw is non-resorbable. It remains stable in the body without degradation by hydrolysis or enzymatic reaction. Depending on the clinical protocol chosen by the implantologist, the screw may require removal during a second surgical intervention, for example, at the time of implant placement after graft consolidation. Precautions for use include precise tightening to avoid any fracture of the screw neck or excessive tapping of the bone. The practitioner must ensure complete coverage of the screw by soft tissues to prevent any post-operative exposure that could lead to bacterial contamination.

Who is the manufacturer and what standards are respected?

This screw is manufactured by Helmut Zepf Medizintechnik GmbH, a manufacturer recognized for its expertise in high-precision dental surgery instrumentation and devices. As a specialized medical device, it is designed according to rigorous manufacturing processes specific to the German medical industry. For detailed information on the regulatory class, specific CE marking, or cleaning and sterilization instructions, healthcare professionals are invited to systematically refer to the instructions for use provided by Helmut Zepf and the product labeling delivered by Delynov.
