Emergency titanium surgical screw, cross-recess, 1.9 mm diameter, 9 mm length - Helmut Zepf (47.575.39) - Delynov

What is the Helmut Zepf titanium emergency screw?

The Helmut Zepf titanium emergency screw is an osteosynthesis device specifically developed for oral reconstructive surgery. Manufactured by Helmut Zepf Medizintechnik GmbH, this bone fixation screw features a titanium structure, a material recognized for its mechanical properties and biocompatibility in physiological environments. With a diameter of 1.9 mm and a length of 9 mm, it has a cross-head socket allowing precise handling with the adapted screwdrivers from the range. This device is primarily used within guided bone regeneration (GBR) protocols to ensure the maintenance of graft structures.

What are the clinical indications for this 9mm titanium screw?

This 9mm titanium screw is indicated for the fixation of autologous bone grafts or bone substitutes in block form during pre-implant surgeries. In implantology and periodontal surgery, it serves to stabilize filler materials or protective membranes against mechanical displacement forces. Its specific format as a surgical emergency screw allows the practitioner to meet increased stabilization needs when the site anatomy or bone quality requires an anchorage of 9 mm depth. It is essential for maintaining the space necessary for bone neoformation without micromovements deleterious to osseointegration.

What are the technical characteristics of reference 47.575.39?

Technical reference 47.575.39 corresponds to a 1 9mm diameter titanium screw with a total length of 9 mm. Its design integrates an optimized thread for facilitated insertion into cortical and cancellous bone, thus minimizing excessive compression stresses. The cross-head is machined to guarantee a perfect match with Helmut Zepf placement instruments, reducing the risk of slippage during screwing. The titanium used ensures corrosion resistance and stable tissue integration. These technical specifications make it a tool of choice for complex cases of alveolar ridge reconstruction.

What are the contraindications for the use of this bone fixation screw?

The use of this bone fixation screw is contraindicated in patients with a known hypersensitivity or allergy to titanium or its alloys. Clinically, it should not be used in areas with an active untreated infection or insufficient vascularization likely to compromise healing. Uncontrolled systemic pathologies, such as severe diabetes or coagulation disorders, may also constitute relative or absolute contraindications. It is the surgeon's responsibility to evaluate the benefit-risk ratio based on the patient's general health status and the quality of the recipient site before any intervention.

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

Being manufactured from titanium, this surgical emergency screw is non-resorbable. It is designed to remain in place throughout the bone consolidation phase, which can vary according to the clinical protocol from a few months to a year. Once regeneration is achieved and before the placement of definitive implants, the practitioner must generally proceed with the explantation of the screw. Precautions for use include tension-free soft tissue coverage to avoid any exposure of the screw head, which could lead to bacterial contamination. Regular radiological follow-up is recommended to verify the stability of the device and the absence of peri-screw bone lysis.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a German company recognized for its expertise in surgical instrumentation and osteosynthesis solutions. As a medical device manufacturer, Helmut Zepf applies rigorous manufacturing processes to guarantee the quality of its products. To obtain precise information on the regulatory class, CE marking, or ISO standards specific to reference 47.575.39, healthcare professionals are invited to systematically refer to the product labeling and the instructions for use provided by the manufacturer. Traceability is ensured by the device's unique reference code.
