Angled conical osteotome insert, size 3, diameter 2 to 4 mm - Helmut Zepf (47.991.30) - Delynov

What is the Helmut Zepf conical angular osteotome insert?

The conical angular osteotome insert, referenced under code 47.991.30, is a specialized surgical instrument designed by Helmut Zepf Medizintechnik GmbH. It is presented as an interchangeable tip intended for bone surgery procedures. Its structure is distinguished by a specific angulation of the shaft, allowing access to difficult-to-reach areas, particularly in the posterior maxillary sectors. The working part adopts a conical shape, essential for progressive penetration into hard tissues. This device is designed to be mounted on a compatible handle, thus offering modularity during implantology or periodontal surgery interventions.

What are the clinical indications for this instrument?

This instrument is primarily indicated for implant site preparation in cases where bone density is insufficient. By using this surgical osteotome tip, the practitioner can achieve lateral and apical bone condensation, which improves the primary stability of the implant. It is also employed for ridge expansion techniques (split control) to progressively widen a narrow alveolar ridge without loss of bone substance. Its angular design makes it particularly useful for crestal approach sinus elevations (internal sinus lift), where it allows for gently pushing back the sinus floor after an initial osteotomy.

What are the technical characteristics of the 47.991.30 insert?

The size 3 Helmut Zepf insert features precise technical specifications to meet the requirements of oral surgery. It has a variable diameter ranging from 2 mm at its distal end to 4 mm at its base, allowing for gradual dilation of the bone tissue. Its conical shape is designed for uniform distribution of forces during compaction. The angulation of the instrument is a major asset for working ergonomics in the mouth, avoiding interference with adjacent teeth or peripheral soft tissues. Technical reference 47.991.30 guarantees the accuracy of dimensions for perfect integration into the Helmut Zepf surgical protocol.

What are the contraindications for the use of this osteotome?

Contraindications for the use of this osteotome insert are related to the physiological limits of bone surgery. Its use is discouraged on excessively corticalized or dense bone (Type D1), where the risk of fracture or overheating is increased without prior rotating instrumentation. Similarly, an insufficient residual ridge width to support expansion may constitute a contraindication to avoid bone dehiscence. As with any metallic instrument, it is appropriate to verify the absence of known patient hypersensitivity to the components of the alloy used by Helmut Zepf Medizintechnik GmbH before any intervention.

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

As a reusable and non-resorbable surgical instrument, this insert requires a rigorous decontamination and sterilization protocol after each use. It must be cleaned with appropriate enzymatic solutions to remove all organic debris, paying particular attention to the connection area and the surgical osteotome tip. Drying must be complete to prevent any corrosion. Sterilization is generally carried out in an autoclave according to the manufacturer's standard parameters. It is recommended to regularly inspect the surface condition and the integrity of the thread or fixation system to ensure safety during clinical procedures.

Who is the manufacturer and what standards are respected?

This insert is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of dental and surgical instrumentation. Although specific details of the CE marking or regulatory class are not mentioned in the source data, Helmut Zepf products are developed according to high quality standards intended for healthcare professionals. The practitioner is invited to systematically refer to the instructions for use and official labeling provided with product 47.991.30 to confirm current certifications and reprocessing protocols recommended by the manufacturer.
