Surgical expansion screw 2.5 x 3.5 mm - Helmut Zepf (47.565.07) - Delynov

What is the Helmut Zepf 2.5 x 3.5 mm surgical expansion screw?

The Helmut Zepf surgical expansion screw is a specialized device designed for bone surgery interventions in implantology and periodontology. This specific model, bearing reference 47.565.07, features dimensions of 2.5 x 3.5 mm, adapted for areas requiring precision intervention. This type of bone expansion screw is an instrument of choice for practitioners performing guided bone regeneration (GBR) protocols. Manufactured by Helmut Zepf Medizintechnik GmbH, it benefits from the expertise of a recognized manufacturer in the field of high-precision surgical instrumentation. Its structure is optimized to meet the mechanical requirements of bone tissue during expansion phases.

What are the clinical indications for this bone expansion screw?

This dental bone expansion screw is primarily indicated in oral surgery procedures aimed at increasing available bone volume. It is used by implantologists and oral surgeons during ridge expansion techniques or the preparation of narrow implant sites. By acting as an osteotome screw, it allows for mechanical stress on the bone to create the necessary space for implant insertion or the placement of bone substitutes. Its use is part of reconstructive dental surgery, particularly when the density or width of the alveolar ridge is insufficient for a standard protocol. It thus facilitates the management of complex clinical cases in guided bone regeneration.

What are the technical characteristics of this Helmut Zepf device?

The Helmut Zepf surgical expansion screw (reference 47.565.07) is characterized by a diameter of 2.5 mm and a length of 3.5 mm. These precise technical specifications allow for localized insertion and targeted action on the bone tissue. As a bone surgery screw, it is designed to withstand the mechanical stresses exerted during screwing into cortical or cancellous structures. The design by Helmut Zepf Medizintechnik GmbH guarantees a thread geometry adapted to primary stability during expansion. Its small size makes it particularly useful for interventions on restricted anatomical sites where space management is critical for the success of dental surgery.

What are the contraindications for the use of this dental surgery screw?

The use of this surgical expansion screw is subject to the practitioner's clinical evaluation. General contraindications include uncontrolled systemic pathologies affecting bone metabolism or healing, such as severe osteoporosis or certain bisphosphonate treatments. Locally, an active infection at the surgical site or an insufficient amount of residual bone to ensure the stability of the screw constitute limits to its use. It is imperative to check for the absence of allergy to the device's metallic components before any intervention. The surgeon must systematically refer to the technical instructions provided by Helmut Zepf to validate the device's compatibility with the patient's physiological state.

What are the precautions for use and handling for this non-resorbable device?

As a non-resorbable metallic device, this bone surgery screw requires rigorous handling. It must be installed using appropriate instruments to avoid any damage to the thread or the screw head. During the planning phase, the practitioner must anticipate the removal of the screw if it is not intended to remain permanently, in accordance with the chosen clinical protocol. Particular attention must be paid to primary stability during placement. As with any Helmut Zepf instrument used in dental surgery, compliance with sterilization and asepsis protocols is mandatory to prevent cross-infection risks and guarantee the integrity of the material before its clinical insertion.

Who is the manufacturer and what standards are met by this product?

The device is manufactured by Helmut Zepf Medizintechnik GmbH, a manufacturer recognized worldwide for the quality of its surgical instruments. Although the specific regulatory class and CE marking are not detailed in the current technical sheet, Helmut Zepf products are developed according to rigorous manufacturing standards specific to German medical instrumentation. As a surgical expansion screw intended for the European market, it meets the safety and performance requirements applicable to medical devices in its category. For any precise information regarding ISO certifications or the specific CE marking for reference 47.565.07, it is advisable to consult the official documentation provided by the manufacturer or contact Delynov.
