CMS, STAINLESS STEEL SCREW Ø 1.0 X 8MM CROSS-SLOT, IDENTIFICATION CAP - Helmut Zepf (47.573.08S) - Delynov

What is the Helmut Zepf 47.573.08S CMS screw?

The CMS screw (47.573.08S) is a micro-osteosynthesis device developed by Helmut Zepf Medizintechnik GmbH. Designed in stainless steel, this steel surgical screw features a diameter of 1.0 mm and a length of 8 mm. It is distinguished by its cruciform head, optimizing torque transmission during insertion, and integrates a specific identification cap. This material is primarily intended for bone reconstruction interventions where precision and primary stability are critical factors for graft success.

What are the clinical indications for this device?

This screw is indicated in oral and implant surgery procedures, particularly for guided bone regeneration (GBR). It allows for the firm fixation of non-resorbable membranes or titanium meshes, as well as the stabilization of small autologous bone blocks or bone substitutes. Its use is essential to prevent any micromovement of the graft material, a sine qua non condition for osseointegration and the formation of new vascularized bone in alveolar defect sites.

What are the technical characteristics of this screw?

The Helmut Zepf model 47.573.08S features precise technical specifications: a body diameter of 1.0 mm and a total length of 8 mm. The stainless steel structure ensures high mechanical resistance against shear stress during placement. The head socket is cruciform, guaranteeing excellent screwdriver grip and reducing the risk of intraoperative slippage. The presence of the identification cap allows the practitioner to quickly confirm the dimensions of the material within the surgical kit.

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

Contraindications related to the use of this steel surgical screw mainly include known hypersensitivity or allergies to stainless steel components. Clinically, it must not be used in sites presenting an active untreated infection or insufficient vascularization of the recipient bed. It is the surgeon's responsibility to evaluate the patient's bone density, as insufficient bone quality could compromise the primary stability of the screw and lead to failure of the regeneration device fixation.

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

As a stainless steel device, this screw is not resorbable by the body. It is designed to maintain mechanical stability throughout the bone healing phase. Depending on the clinical protocol established by the practitioner, a second intervention may be necessary for its removal once the regeneration objective is achieved. The surgeon must ensure total, tension-free gingival coverage to avoid any premature exposure of the screw, which could compromise the asepsis of the surgical site.

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 instrumentation. Production follows rigorous protocols to guarantee the reliability of the fixation devices. Although detailed regulatory specifications are not listed here, Helmut Zepf products are developed to meet the requirements of oral health professionals. It is imperative to systematically refer to the instructions for use and the manufacturer's instructions for sterilization procedures and applicable compliance standards.
