Angulated conical surgical osteotome insert, size 5, diameter 3-5 mm - Helmut Zepf (47.991.50) - Delynov

What is the Helmut Zepf angular conical surgical osteotome insert?

The angular conical surgical osteotome insert by the Helmut Zepf brand is a precision instrument intended for implant surgery. This device, identified under reference 47.991.50, is an interchangeable tip of size 5. Its structure is characterized by a specific conical shape and an angulation of the handle or shaft, facilitating work in difficult-to-access areas. As part of the Helmut Zepf range, this insert is designed to meet the requirements of modern surgical protocols, offering a standardized interface for practitioners specializing in implantology and oral surgery.

What are the clinical indications for this implant surgery insert?

This surgical osteotome insert is primarily indicated for implant bed preparation procedures, particularly in cases of low-density bone (Type III or IV). It is used to perform alveolar ridge expansion or apical bone condensation, often necessary during crestal approach sinus lift techniques. Its angular configuration is particularly suited to the posterior maxillary and mandibular sectors, where limited mouth opening makes the use of straight instruments complex. The clinical objective is to improve the primary stability of the implant by optimizing peripheral bone density without substantial material removal.

What are the technical characteristics of the 47.991.50 conical osteotome tip?

The Helmut Zepf reference 47.991.50 insert features precise technical specifications for calibrated osteotomy. It is a size 5 conical osteotome tip, displaying a progressive diameter ranging from 3 mm at its working base to 5 mm at its widest part. This taper allows for gradual and controlled expansion of the bone walls. The instrument is designed with a specific angulation to improve ergonomics and visibility during insertion. Manufacturing is based on the precision standards of Helmut Medizintechnik GmbH, ensuring compatibility with the appropriate instrument handles from the same range for optimal force transmission.

What are the contraindications for the use of this instrument?

Although specific contraindications are not detailed in the raw technical data, the use of this surgical osteotome insert should be avoided in clinical situations where bone expansion is prohibited, such as in the presence of extremely thin and brittle cortical bone or highly mineralized Type I bone presenting a risk of fracture. Generally, use is contraindicated in patients with uncontrolled systemic pathologies affecting bone healing or in cases of known allergy to the metallic components of the surgical instrumentation. The practitioner must refer to the manufacturer's instructions for use to validate the suitability of the device with the patient's health status.

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

As a reusable surgical instrument, this Helmut Zepf insert requires a rigorous decontamination and sterilization protocol after each intervention. The tip should be carefully cleaned to remove all organic debris in the threaded areas or at the conical tip. Precautions include the use of non-corrosive cleaning solutions and compliance with the autoclave cycles recommended by the manufacturer. A visual inspection of the surface condition and thread integrity is recommended before each use to ensure patient safety and the effectiveness of the surgical procedure. Storage in a dry and protected environment prevents any premature alteration of the instrument.

Who is the manufacturer and what standards are respected?
