Screw-in conical osteotome insert, straight, size 2, Ø 2-3 mm - Helmut Zepf (47.990.30) - Delynov

What is the Helmut Zepf screw-in conical osteotome insert?

The Helmut Zepf screw-in conical osteotome insert (reference 47.990.30) is a specialized surgical instrument used in implantology. This device comes in the form of a removable straight osteotome tip, designed to be fixed to a compatible handle via a screw system. Its structure is characterized by a size 2 working end, featuring a progressive taper ranging from a diameter of 2 mm to 3 mm. Manufactured by Helmut Zepf Medizintechnik GmbH, this instrument is intended for oral surgery procedures requiring precise manipulation of alveolar bone tissue. Its design allows for rigorous axial insertion, essential for ensuring primary stability during the preparation of implant recipient sites.

What are the clinical indications for this dental osteotome insert?

This dental osteotome insert is primarily indicated for bone condensation and expansion techniques in the maxillary or mandibular sectors. In implant surgery, it is used to prepare the implant housing when bone density is insufficient (Type III or IV bone). Its conical shape allows for lateral compression of the bone trabeculae rather than removing them, thereby locally increasing density around the implant. It is also employed in crestal sinus lift protocols to condense filling material or for the controlled expansion of a narrow ridge, thus avoiding the need for more invasive drilling techniques that could compromise residual bone volume.

What are the technical characteristics of insert 47.990.30?

The implantology equipment referenced 47.990.30 by Helmut Zepf features precise technical specifications to meet the requirements of oral surgery. It is a size 2 insert, equipped with a straight geometry for direct access to surgical areas. The active part is conical, with an initial diameter of 2 mm widening to 3 mm, allowing for smooth and calibrated progression into the bone. The screw-in fixation system allows for perfect connection with the handle, ensuring efficient transmission of manual force. Its straight design is particularly suited for procedures on anterior and premolar sectors, offering optimal visibility and increased tactile control during the bone expansion phase.

What are the contraindications for the use of this instrument?

The use of this osteotome insert is contraindicated in clinical situations where the bone density is too high (Type I bone), as the attempt at expansion could lead to cortical fractures or overheating due to friction. It must not be used in patients with general contraindications to implant surgery, such as uncontrolled bone healing disorders or severe metabolic pathologies. Furthermore, the use of this instrument requires specific training in osteotomy techniques; inappropriate application of force or an incorrect insertion axis can lead to perforation of the bone walls or injury to adjacent anatomical structures such as the maxillary sinus or the inferior alveolar nerve.

What are the maintenance precautions for this implantology equipment?

Like all Helmut Zepf bone surgery instruments, this insert requires a strict protocol of cleaning, disinfection, and sterilization after each use. Although specific composition details are not provided, this type of instrument must be visually inspected for any signs of wear, corrosion, or thread deformation before each intervention. A damaged thread could compromise the fixation to the handle and create a clinical risk. It is recommended to follow the instructions from the manufacturer Helmut Zepf Medizintechnik GmbH regarding autoclave cycles and the use of non-corrosive cleaning solutions to preserve the structural integrity and dimensional precision of the 2 to 3 mm tip.

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. As a medical device intended for invasive surgery, it must meet the regulatory requirements in force for the marketing of medical devices. Although the specific regulatory class and CE marking are not explicitly detailed in the source data, Helmut Zepf products are designed to satisfy the high quality standards required for professional clinical use. Practitioners are invited to consult the manufacturer's technical manual and labeling to verify specific certifications and instructions for use in accordance with European directives on medical devices.
