Angulated conical osteotome insert, size 2, diameter 2 to 3 mm - Helmut Zepf (47.991.20) - Delynov

What is the Helmut Zepf conical angular osteotome insert?

The Helmut Zepf conical angular osteotome insert, referenced under code 47.991.20, is a specialized instrument for oral bone surgery. This size 2 device features an angular structure and a conical geometry, specifically designed to adapt to expansion or condensation protocols. Manufactured by Helmut Zepf Medizintechnik GmbH, this instrument is intended to be mounted on a compatible handle to allow the practitioner to exert controlled forces on the bone tissue. Its design meets the requirements of modern implant surgery where the preservation and optimization of bone volume are critical.

What are the clinical indications for this instrument?

This instrument is primarily indicated in implant surgery and oral surgery procedures requiring manipulation of bone volume. It is used for the expansion of narrow ridges, allowing for the creation of an implant housing without excessive material removal. The osteotome tip is also employed for the condensation of cancellous bone, thereby increasing local bone density and improving the primary stability of the implant. Its angular shape is particularly useful for accessing posterior sectors or zones where the insertion axis requires an offset compared to conventional straight instruments.

What are the technical characteristics of the 47.991.20 insert?

The Helmut Zepf insert (reference 47.991.20) is distinguished by its precise dimensions and specific shape. It is a size 2 model, characterized by a progressive diameter ranging from 2 to 3 mm. This taper allows for gradual insertion and controlled dilation of the bone walls. The angular nature of the shaft offers optimized visibility and access in complex clinical configurations. As a removable element, it must be associated with a standard osteotome handle from the brand to guarantee efficient energy transmission during manual impaction.

What are the contraindications for the use of this osteotome?

Contraindications for the use of this osteotome insert include clinical situations where bone density is excessive (highly mineralized Type D1 bone), which could lead to a risk of ridge fracture during expansion. It must not be used in patients presenting general contraindications to oral surgery, such as uncontrolled coagulation disorders or severe systemic bone pathologies. Furthermore, the use of this instrument is prohibited if the practitioner does not have sufficient residual bone volume to support the mechanical stresses of expansion without risk of dehiscence.

What are the maintenance and durability precautions?

Like any Helmut Zepf precision surgical instrument, this insert requires a rigorous decontamination and sterilization protocol after each use. Although material specifications are not detailed here, these devices are generally designed to withstand standard autoclave cycles. It is imperative to check the integrity of the tip and the connection thread before each intervention. Any deformation of the active part or wear of the depth marking can compromise the precision of the surgical gesture and requires the replacement of the insert to maintain the safety of care.

Who is the manufacturer and what standards are met?

This insert is produced by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of dental and surgical instrumentation. Although the specific regulatory class and CE marking are not explicitly mentioned in the technical data provided, Helmut Zepf is renowned for following high-quality manufacturing processes compliant with medical sector requirements. Practitioners are invited to systematically refer to the instructions for use and official labeling delivered with the product to confirm current certifications and specific reprocessing instructions.
