Angulated conical osteotome insert, size 8, diameter 5 to 6 mm - Helmut Zepf (47.991.80) - Delynov

What is the Helmut Zepf angular osteotome insert?

The Helmut Zepf angular osteotome insert, referenced under code 47.991.80, is a specialized surgical instrument used in implantology and oral surgery. This device is distinguished by its angular structure and its size 8 conical tip. Designed by the manufacturer Helmut Zepf Medizintechnik GmbH, this instrument is intended to be integrated into an implant site preparation protocol where precise manipulation of the bone structure is required. Its design allows access to posterior or difficult-to-reach areas thanks to its specific angulation, thus offering an alternative to classic straight instruments during the bone condensation or expansion phases.

What are the clinical indications for this insert?

This angular osteotome insert is primarily indicated for pre-implant surgery procedures. It is used by dental surgeons and implantologists for the expansion of narrow ridges, allowing the creation of an implant housing without loss of bone substance. Another major indication concerns crestal sinus lifts, where the instrument allows for the condensation of autologous bone or bone substitutes under the sinus membrane. Its conical shape is ideal for increasing local bone density through lateral compression, which is particularly beneficial in low-density bone (type III or IV) to ensure better implant stability.

What are the technical characteristics of the 47.991.80 insert?

The Helmut Zepf insert (reference 47.991.80) features precise technical specifications to meet the requirements of oral surgery. It is a size 8 model displaying a progressive diameter ranging from 5 to 6 mm. This taper allows for controlled insertion and gradual expansion of the bone tissue. The angulation of the insert body is designed to optimize the working axis, particularly in the posterior maxillary sectors where the patient's mouth opening may limit the use of straight instruments. The manufacturing quality of Helmut Zepf Medizintechnik GmbH ensures efficient transmission of forces during manual or percussive use, depending on the protocol chosen by the practitioner.

What are the contraindications for the use of this instrument?

The contraindications for the use of this osteotome insert are related to the physiological limits of bone surgery and implantology protocols. It should not be used if the residual bone volume is insufficient to support expansion without the risk of fracturing the bone plate. Furthermore, its use is discouraged in patients with serious systemic pathologies affecting bone healing or in cases of active local infections at the surgical site. As with any metal instrument, a known hypersensitivity to the alloy components constitutes a contraindication. The practitioner must evaluate bone density through preoperative imaging to validate the relevance of using a conical osteotome of this diameter.

What are the maintenance and durability precautions?

As an instrument in the CONSO category at Delynov, this Helmut Zepf insert requires a strict sterilization protocol between each patient. Although specific resorption details do not apply here as it is a non-implantable instrument, the durability of the insert depends on compliance with cleaning and decontamination cycles. It is recommended to use non-corrosive cleaning solutions and to check the condition of the conical tip and the threading before each intervention. Any deformation or blunting of the active part (diameter 5 to 6 mm) can alter the precision of the surgical gesture and requires the replacement of the instrument to guarantee the safety of care and the effectiveness of the bone expansion.

Who is the manufacturer and what standards are respected?

The official manufacturer of this insert is Helmut Zepf Medizintechnik GmbH, a company recognized in the dental and surgical instrumentation sector for its technical expertise. The product is distributed by Delynov under the name 'Conical angular osteotome insert, size 8'. Regarding standards and certifications, although specific regulatory class or CE marking data are not detailed in the current technical sheet, Helmut Zepf products are generally designed according to the rigorous quality standards specific to oral surgery medical devices. For any precise information on regulatory compliance or to consult the instructions for use, it is imperative to refer to the documents provided by the manufacturer Helmut Zepf when acquiring the equipment.
