CMS, TITANIUM MICRO-SCREW, DIAM.1.5X12MM CROSS-RECESSED, BLUE ANODIZED - Helmut Zepf (47.575.12) - Delynov

What is the Helmut Zepf 1.5x12mm titanium micro screw?

The Helmut Zepf titanium micro screw, reference 47.575.12, is a precision osteosynthesis device used in oral surgery. Manufactured from titanium, it features a robust structure adapted to the mechanical stresses of the maxillofacial area. This specific model has a diameter of 1.5mm and a length of 12mm. Its surface is treated by blue anodization, allowing for rapid visual identification during the procedure and facilitating localization within the tissues or during its subsequent removal. It features a cross-head drive, optimizing torque transmission during screwing and ensuring connection stability with the dedicated screwdriver.

What are the clinical indications for this micro screw?

This micro osteosynthesis screw is primarily indicated in Guided Bone Regeneration (GBR) protocols. It is used by dental surgeons and implantologists to securely fix autologous bone grafts or biomaterials during ridge augmentations. It also allows for the stabilization of non-resorbable or resorbable membranes, thereby preventing any micromovement that could hinder neovascularization and the formation of newly formed bone. Its use is common in cases of complex bone defects where rigid mechanical fixation is necessary to guarantee the success of future implant placement.

What are the technical characteristics of reference 47.575.12?

Reference 47.575.12 is distinguished by rigorous technical specifications. It features a body diameter of 1.5mm, ideal for surgical sites with restricted bone volume while offering satisfactory primary stability. Its total length of 12mm allows for deep anchoring in cortical and cancellous bone. The cross-head drive reduces the risk of the instrument slipping during insertion. The titanium used by Helmut Zepf Medizintechnik GmbH is selected for its mechanical properties and biocompatibility. Blue anodization is an additional technical feature facilitating stock management and surgical tray organization.

What are the contraindications for the use of this device?

The use of this titanium micro screw is contraindicated in patients with a known hypersensitivity to titanium or its alloys. Clinically, it should not be used if the residual bone quality or quantity is insufficient to ensure the primary stability of the device. Uncontrolled systemic pathologies affecting bone metabolism, poor oral hygiene, or an active infection at the surgical site also constitute major contraindications. It is the practitioner's responsibility to evaluate the benefit-risk ratio based on the patient's general health status and the specificities of the site to be treated.

What precautions are associated with the non-resorbable nature of titanium?

Being manufactured from titanium, this micro screw is non-resorbable. It is designed to remain in place throughout the bone healing phase, generally several months. Depending on the treatment plan, it can be left permanently or removed during a second surgical stage, for example, at the time of implant placement. The practitioner must ensure that the screw is completely covered by soft tissue to avoid any exposure, which is a risk factor for infection. During removal, the use of the appropriate Helmut Zepf cross-head instrumentation is imperative to avoid damaging the screw head drive.

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 for the high precision of its products. The design of this micro screw meets the strict quality requirements of the German company. Although specific details of the CE marking or regulatory class are not provided in this document, Helmut Zepf products are developed according to high industrial standards to guarantee patient safety and reliability for users. Practitioners are invited to consult the instructions for use and product labeling to verify current certifications.
