Reinforced titanium surgical pin, 1mm diameter, 0.8mm shank - Helmut Zepf (47.561.06) - Delynov

What is the Helmut Zepf 47.561.06 surgical pin?

The Helmut Zepf surgical pin, reference 47.561.06, is a bone fixation device designed in reinforced titanium. This material is selected for its mechanical properties and biocompatibility in the oral environment. The product features a specific structure with a head or body diameter of 1mm and a 0.8mm shaft, allowing for precise intervention. This type of titanium surgery pin is used to stabilize elements during complex reconstructions, offering a robust solution for maintaining hard structures or filling materials under soft tissues.

What are the clinical indications for this titanium pin?

This bone fixation pin is primarily indicated in oral and implant surgery protocols requiring strict immobilization. It is used for the fixation of membranes (membrane fixation nail) or autogenous and allogenic bone grafts during Guided Bone Regeneration (GBR) procedures. Its reinforced titanium design maintains the primary stability necessary for the consolidation of the operative site. It is used during bone volume augmentation, where the displacement of materials could compromise the success of future implant placement.

What are the technical characteristics of this fixation nail?

The Helmut Zepf device is distinguished by precise dimensions: a main diameter of 1mm associated with a 0.8mm shaft. This thinness allows for insertion with reduced bone trauma while maintaining sufficient resistance to deformation thanks to the reinforced titanium. As a dental surgery pin, its geometry is optimized for easy gripping with dedicated placement instruments from the Helmut Zepf range. The use of titanium ensures excellent resistance to corrosion and favorable tissue integration throughout the clinical maintenance phase.

What are the contraindications for the use of this device?

Contraindications for the use of this titanium membrane pin mainly include known allergies or hypersensitivities to titanium or its alloys. Clinically, use is prohibited in areas with active infection, insufficient vascularization, or inadequate bone density to ensure anchoring of the device. Patients with uncontrolled systemic disorders affecting bone healing, such as severe diabetes or untreated osteoporosis, may present increased risks. It is the practitioner's responsibility to evaluate the benefit/risk ratio according to the patient's general health status.

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

This titanium surgery nail is manufactured from a non-resorbable material, which means it does not degrade in the body. It remains stable for the entire duration required for bone regeneration. Depending on the clinical protocol and the fixation objective, a second intervention may be necessary to remove the pin once bone consolidation or graft integration is achieved. The practitioner must ensure that the pin is perfectly covered by soft tissues to avoid premature exposure, which could lead to bacterial contamination of the graft site.

Who is the manufacturer and what are the recommendations for use?

The device is manufactured by Helmut Zepf Medizintechnik GmbH, a manufacturer recognized for the high precision of its surgical instruments. As a product intended for invasive surgery, it must be handled exclusively by healthcare professionals trained in implantology and oral surgery techniques. Although specific regulatory specifications (class, CE marking) are not detailed here, Helmut Zepf products are designed according to rigorous quality standards. It is imperative to systematically refer to the instructions for use and the manufacturer's recommendations for sterilization and placement protocols.
