BONE BLOCK HOLDER - Helmut Zepf (47.956.20) - Delynov

What is the Helmut Zepf bone block holder (47.956.20)?

The bone block holder developed by Helmut Zepf is a specialized instrument used in oral and implant surgery. This technical device, referenced under code 47.956.20, serves as a stable working base for the practitioner during graft manipulation. Its structure is designed to receive and immobilize a fragment of autologous bone or a bone substitute, thereby facilitating pre-implant preparation steps. As a surgical accessory, it allows for rigorous management of graft material, ensuring the block remains in the optimal position while the surgeon performs the necessary adjustments for its adaptation to the recipient site.

What are the clinical indications for this bone block holder?

The use of this bone graft holder is indicated during all interventions requiring alveolar ridge reconstruction or sinus filling. In implant surgery, graft stabilization is crucial for adapting its morphology to the implantation site. This device specifically intervenes during extra-oral preparation phases, where the surgeon must trim, perforate, or refine the bone block before its final fixation. It proves particularly useful in cases of severe bone atrophy requiring block grafts, allowing for secure and precise manipulation of the reconstruction material without risk of accidental falling or contamination during shaping.

What are the technical characteristics of this holder?

The Helmut Zepf bone block holder, identified by reference 47.956.20, features characteristics adapted to the requirements of oral surgery. Its design is based on ergonomics allowing for fast and reliable graft fixation. Although specific dimensions are not detailed, this instrument is designed to withstand standard sterilization cycles in dental offices or hospital environments. The manufacturing quality of Helmut Medizintechnik GmbH ensures the durability and corrosion resistance necessary for surgical instruments. The design of the surgical bone block holder is optimized to offer maximum visibility to the practitioner while firmly holding the graft material during mechanical stresses related to cutting.

What are the contraindications for the use of this instrument?

There are no specific documented medical contraindications for the use of this work support, as it does not come into permanent contact with the patient. However, standard surgical precautions apply: the instrument must not be used if it shows visible signs of degradation, corrosion, or mechanical dysfunction of the holding system. Its use is strictly reserved for qualified health professionals in oral surgery and implantology. Practitioners should refer to the manufacturer's technical instructions to ensure the compatibility of the device with current cleaning and sterilization methods to avoid any risk of cross-contamination.

What are the maintenance precautions for this non-resorbable device?

As a reusable steel surgical instrument, the Helmut Zepf bone block holder requires a rigorous maintenance protocol after each intervention. It must undergo immediate decontamination, followed by manual cleaning or an ultrasonic bath, then sterilization in an autoclave according to the parameters recommended by Helmut Zepf Medizintechnik GmbH. It is essential to check for the absence of organic residues in the clamping mechanisms or on the surface of the support. Complete drying is imperative before sterilization to prevent any risk of oxidation. Compliance with these steps guarantees the maintenance of the functional properties of the bone block holder and ensures the safety of subsequent surgical procedures.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized company in the high-precision dental and surgical instrumentation sector. Based in Germany, this manufacturer applies production processes compliant with the demanding quality standards of the medical industry. Although the specific regulatory class and CE marking are not detailed in the simplified technical documentation, Helmut Zepf products are designed to meet the safety and performance requirements applicable to medical devices in Europe.
