Screw-in osteotome insert, straight, conical, 2-4mm diameter, size 3 - Helmut Zepf (47.990.40) - Delynov

What is the Helmut Zepf screw-on osteotome insert?

The Helmut Zepf osteotome insert (reference 47.990.40) is a bone surgery instrument designed to be mounted on an interchangeable handle. This specific model features a straight structure and a conical active tip. Manufactured by Helmut Zepf Medizintechnik GmbH, this instrument is intended for bone preparation procedures prior to implant placement. Its screw-on design allows for optimal modularity during oral surgery procedures, offering the practitioner the possibility to change inserts according to clinical needs without changing the complete handle.

What are the clinical indications for this size 3 insert?

This osteotome insert is primarily indicated for ridge expansion and bone condensation techniques. In implant surgery, it is used to prepare the implant bed in areas where bone density is low, such as the upper maxilla. The conical shape allows for lateral compression of the bone walls rather than removing them by drilling, which improves local density. It can also be used during crestal sinus lift procedures to condense filling materials or for osteotomy preparation of the sinus floor.

What are the technical characteristics of the 47.990.40 insert?

The Helmut Zepf insert reference 47.990.40 is characterized by a straight shape and a size 3 conical geometry. The dimensions of the active part feature a progressive diameter ranging from 2 mm to 4 mm. This graduation allows for controlled and sequential widening of the osteotomy site. The instrument is designed to fit by screwing onto handles from the Helmut Zepf range, ensuring precise axial force transmission during manual or mallet use. Its technical finish meets the requirements of oral surgery for rigorous handling.

What are the contraindications for the use of this osteotome?

The use of this osteotome insert is contraindicated in clinical situations where the cortical bone is extremely dense or brittle, which could lead to ridge fractures during expansion. It should not be used if the residual bone volume is insufficient to support the mechanical stresses of expansion. Generally, as with any surgical instrument, use is prohibited in patients with systemic contraindications to oral surgery or non-stabilized bone pathologies. The instructions for use provided by the manufacturer should systematically be consulted to validate clinical compatibility.

What are the maintenance and sterilization precautions?

As a reusable metallic surgical instrument, this insert must undergo a complete decontamination, cleaning, and sterilization protocol before each use. It is recommended to use neutral pH cleaning solutions to preserve the surface condition of the steel and the connection thread. The practitioner must check the integrity of the screw thread and the active tip before any intervention. Wear or deformation of the insert could compromise the precision of the surgical gesture or the safety of the fixation on the handle. Sterilization must be performed by autoclave according to the standard cycles recommended by Helmut Zepf Medizintechnik GmbH.

Who is the manufacturer and what standards are respected?
