Titanium emergency cross-slot screw for microvascular surgery, Ø 1.9 mm, length 6 mm - Helmut Zepf (47.575.36) - Delynov

What is the Helmut Zepf emergency cross-head screw?

The Helmut Zepf emergency cross-head screw is a miniaturized fixation device designed for microvascular surgery and guided bone regeneration (GBR) procedures. Made of titanium, this microsurgery screw features a diameter of 1.9 mm and a length of 6 mm. Its structure is optimized to provide effective primary stability in situations where a standard screw might not suffice or requires backup anchoring. The cross-head allows for precise axial force transmission during insertion, reducing the risk of instrument slippage. This component is a key element of the therapeutic arsenal for practitioners performing complex grafts or stabilization of thin tissues.

What are the clinical indications for this 6mm titanium screw?

This 6mm titanium screw is primarily indicated for the fixation of regeneration membranes, titanium meshes, or small bone fragments during alveolar reconstruction surgeries. In microvascular surgery, it serves as an anchor or support point for delicate structures requiring rigid containment. Implantologists and oral surgeons frequently use it in GBR cases where available space or bone density necessitates the use of a 1.9 mm diameter screw. Its design allows for the securing of graft material, thus preventing micromovements harmful to osseointegration and the healing of surrounding soft tissues.

What are the technical characteristics of reference 47.575.36?

Reference 47.575.36 from manufacturer Helmut Zepf Medizintechnik GmbH is distinguished by rigorous specifications: a body diameter of 1.9 mm and a total length of 6 mm. These dimensions classify it among microsurgery solutions for areas with low bone volume. The cross-head drive is machined to match perfectly with the range's screwdrivers, ensuring stable retention of the device during transport to the implant site. The choice of titanium as the constituent material ensures excellent mechanical strength while meeting the biocompatibility requirements necessary for prolonged or temporary integration into the maxillary or mandibular bone.

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

Contraindications for the use of this titanium microsurgery screw primarily include known hypersensitivities to titanium or its alloys. Clinically, it should not be used if the residual bone volume is insufficient to support a 1.9 mm diameter without risking a ridge fracture or damage to adjacent anatomical structures (nerves, sinuses). Active infection at the surgical site or severely compromised local vascularization also constitute major contraindications. It is the practitioner's responsibility to evaluate bone quality and the patient's general health status, particularly metabolic pathologies affecting bone healing, before any placement of osteosynthesis material.

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

As this microvascular surgery screw is made of titanium, it is non-resorbable. This means it will remain in place permanently unless a secondary procedure is scheduled for its removal, generally after the bone consolidation phase or graft integration. The practitioner must ensure that the screw head does not create irritation or dehiscence of the overlying soft tissues. Total tension-free mucosal coverage is recommended to avoid premature exposure. If removal is planned, it is advised to precisely record the location and drive type (cross-head) in the patient file to facilitate subsequent explantation with the appropriate Helmut Zepf instrumentation.

Who is the manufacturer and what are the quality guarantees?

The device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-precision surgical and dental instrumentation. Although specific data on the regulatory class or CE marking are not detailed here, Helmut Zepf products are developed according to strict industrial standards to meet the needs of specialized operating theaters. Each screw, such as reference 47.575.36, undergoes rigorous quality controls during its production in Germany. Professionals can refer to the instructions for use and manufacturer protocols for detailed information on sterilization methods and specific implementation recommendations for this microsurgery equipment.
