Titanium cross-slot screw for microscopic surgery, Ø 1.5 mm, length 10 mm, blue anodized - Helmut Zepf (47.575.10) - Delynov

What is the Helmut Zepf 47.575.10 Phillips screw?

The Phillips screw referenced 47.575.10 by Helmut Zepf is a bone fixation device made of titanium, specifically developed for microscopic surgery. This component is distinguished by its optimized structure for guided bone regeneration (GBR) procedures. Its titanium composition ensures excellent integration within the oral physiological environment, while its blue anodization facilitates visual identification during placement or removal. This device is designed to meet the precision requirements of practitioners specialized in implantology and periodontology when stabilizing grafts or protective barriers.

What are the clinical indications for this titanium screw?

This 1.5 mm diameter titanium screw is primarily indicated in oral and implant surgery protocols requiring rigid fixation. Its use is recommended during bone grafts, particularly for maintaining non-resorbable membranes or fixing autogenous or allogenic bone blocks. In microscopic surgery, it allows for securing regeneration material in difficult-to-access areas or during complex volumetric reconstructions. The clinical objective is to ensure perfect primary stability of the filling material or membrane to promote optimal neo-angiogenesis and osseointegration without disruptive micromovements.

What are the technical characteristics of the Helmut Zepf screw?

The Helmut Zepf screw features rigorous technical specifications for micro-surgery. It has a diameter of 1.5 mm and a total length of 10 mm, offering an ideal compromise between fineness and mechanical strength for cortical anchoring. The head drive is a Phillips type, allowing for efficient torque transmission and screw stability on the screwdriver during insertion. The blue anodized surface treatment is not merely aesthetic; it allows for quick differentiation of dimensions within a surgical kit and improves corrosion resistance. This device is a product of the expertise of Helmut Zepf Medizintechnik GmbH.

What are the contraindications for the use of this device?

Contraindications for the use of the Helmut Zepf titanium screw primarily include cases of hypersensitivity or known allergy to titanium or its alloys. Clinically, its use is discouraged in sites presenting an active untreated infection or insufficient vascularization of the recipient bone, which would compromise the success of the regeneration surgery. Additionally, insufficient residual bone volume to ensure anchoring of the 10 mm screw length constitutes a technical contraindication. It is the surgeon's responsibility to evaluate systemic risk factors, such as coagulation disorders or uncontrolled bone metabolic pathologies, before any intervention.

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

Being made of titanium, this screw is a non-resorbable device. It is designed to remain in place throughout the bone healing phase and graft maturation. Depending on the clinical protocol chosen by the practitioner, the screw may require removal during a second surgical stage, for example, at the time of implant placement or removal of a non-resorbable membrane. Precautions for use include controlled screwing to avoid any fracture of the bone crest or excessive compression. Storage and handling must be performed under strict aseptic conditions to prevent any risk of cross-contamination before implantation.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized player in the manufacture of instruments and devices for high-precision dental surgery. Although specific data on the regulatory class or CE marking are not detailed in the provided sources, Helmut Zepf products are developed according to rigorous industrial quality standards.
