Titanium microsurgical emergency screw, Ø 1.4 mm, length 10 mm, cross-head - Helmut Zepf (47.574.40) - Delynov

What is the Helmut Zepf microsurgical emergency screw?

The Helmut Zepf microsurgical emergency screw is a precision osteosynthesis device manufactured by Helmut Zepf Medizintechnik GmbH. Designed in titanium, a material recognized in the surgical field for its mechanical properties and biocompatibility, this screw has a diameter of 1.4mm and a length of 10mm. Its structure is optimized for microsurgery with a cross-head (cruciform) socket, allowing for rigorous handling during the phases of screwing into bone tissue. It belongs to the category of Guided Bone Regeneration (GBR) devices distributed by Delynov, offering a reliable technical solution for practitioners demanding high-precision components for their reconstruction procedures.

What are the clinical indications for this titanium microsurgery screw?

The use of this osteosynthesis emergency screw is primarily indicated in oral and maxillofacial surgery, particularly within the framework of guided bone regeneration. It is used for the immobilization of autologous bone blocks or protective membranes during alveolar ridge augmentation. Its 1.4mm diameter titanium design makes it particularly suitable for situations where available space is limited or when bone density requires specific anchoring. As a dental emergency screw, it secures surgical assemblies in various clinical contexts, guaranteeing the primary stability essential for osseointegration and the long-term success of the implant treatment plan.

What are the technical characteristics of reference 47.574.40?

Technical reference 47.574.40 corresponds to a titanium emergency screw whose specifications are rigorously defined to meet the needs of microsurgery. It features a body diameter of 1.4mm, making it an instrument of choice for narrow surgical sites. Its total length is 10mm, providing sufficient anchoring depth to stabilize bone grafts. The screw head is a cross-head (cruciform) type, a geometry that ensures excellent stability of the screwdriver bit, thereby reducing the risks of slipping or deforming the socket when applying the torque necessary for fixation.

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

Although specific manufacturer data is not detailed here, general contraindications for an osteosynthesis emergency screw include known allergies to titanium or its alloys. Clinically, use is discouraged in cases of active infection at the surgical site, uncontrolled systemic pathologies affecting bone metabolism (such as severe osteoporosis or ongoing radiotherapy), or insufficient oral hygiene of the patient. It is the surgeon's responsibility to evaluate the quality of the residual bone volume to ensure that the 1.4mm by 10mm dimensions are compatible with the sought-after mechanical stability without compromising adjacent anatomical structures.

What precautions are associated with the non-resorbable titanium material?

This titanium emergency screw is a non-resorbable device, meaning it maintains its structural integrity indefinitely after placement. Unlike resorbable polymers, titanium does not undergo hydrolysis. Depending on the clinical protocol chosen by the Helmut Zepf practitioner, the screw can remain in place permanently if it is perfectly integrated and covered, or be removed during a second surgical step, for example, at the time of implant placement. Precautions include controlled tightening to avoid any fracture of the bone ridge and adequate mucosal coverage to prevent exposure of the hardware, thus ensuring optimal healing of the surrounding soft tissues.

Who is the manufacturer Helmut Zepf and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized player in the production of surgical instrumentation and high-quality osteosynthesis solutions. Although specific certifications (such as regulatory class or CE marking) are not explicitly mentioned in this sheet, Helmut Zepf products are developed according to strict industrial standards to meet the requirements of dental and maxillofacial surgery. Practitioners are invited to systematically refer to the instructions for use and the labeling of the delivered product to verify regulatory compliance information, recommended sterilization protocols, and the device's validity dates.
