Screw-in osteotome insert, straight, conical, Ø 3-5 mm, size 5 - Helmut Zepf (47.990.60) - Delynov

What is the Helmut Zepf screw-in osteotome insert (47.990.60)?

The Helmut Zepf screw-in osteotome insert is a removable surgical instrumentation component intended for implantology practice. This specific model features a straight structure and a size 5 conical geometry. Manufactured by Helmut Zepf Medizintechnik GmbH, this device is designed to be attached to a compatible handle for interventions on bone tissue. Its design allows for efficient force transmission during manual maneuvers. As a screw-in osteotome, it offers appreciated modularity in oral surgery, allowing the practitioner to change the working end according to the clinical needs of the procedure without changing the entire instrument.

What are the clinical indications for this straight osteotome insert?

This straight osteotome insert is primarily indicated for ridge expansion and bone condensation procedures 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). The conical shape of the instrument allows for lateral bone compaction, thereby increasing the primary stability of the future implant. It is also employed in crestal approach sinus lift techniques to gently push back the sinus floor after an initial osteotomy. Its use is reserved for dental surgeons and stomatologists trained in reconstructive bone surgery techniques.

What are the technical characteristics of the 47.990.60 insert?

The insert referenced 47.990.60 by Helmut Zepf is distinguished by its precise dimensions and functional shape. It is a size 5 instrument, featuring a conical diameter varying from 3 mm at its thinnest end to 5 mm at its base. This taper is specifically studied for progressive and controlled penetration into the bone tissue. The working part is straight, facilitating direct access to surgical sites, particularly in anterior areas or easily accessible posterior areas. The screw-in fixation system guarantees perfect connection with the handle, avoiding any mechanical play during the application of pressure or percussion forces.

What are the contraindications for the use of this instrument?

Contraindications for the use of this screw-in osteotome tip are related to the general limits of oral surgery and patient specificities. Its use is contraindicated in the presence of active bone pathology at the operative site, such as osteomyelitis or a malignant tumor. Additionally, insufficient residual ridge thickness to support expansion without risk of major cortical fracture constitutes a clinical contraindication. Patients with bone healing disorders or general contraindications to implant surgery should not undergo such procedures. It is also necessary to verify the absence of allergy to the metals constituting the surgical instrumentation before any intervention.

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

As a reusable stainless steel surgical instrument, this insert requires a strict protocol of decontamination, cleaning, and sterilization between each patient. After each use, the insert must be unscrewed from its handle to ensure complete cleaning of the thread, an area prone to the accumulation of organic debris. It is recommended to use neutral pH cleaning solutions and avoid chlorinated agents that could alter the instrument's surface. Sterilization must be performed by steam autoclave according to the cycles validated by the manufacturer Helmut Zepf. A visual inspection of the thread condition and the integrity of the conical part is essential before each return to service to guarantee operative safety.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-precision dental and surgical instrumentation. Based in Germany, this company applies rigorous manufacturing standards to guarantee the reliability of its products. Although the specific regulatory class and CE marking are not detailed in this technical sheet, instruments produced by Helmut Zepf are designed to meet the professional quality requirements of the medical sector. It is the practitioner's responsibility to consult the instructions for use provided by the manufacturer to become aware of the specific certifications and safety instructions for reference 47.990.60 before any clinical implementation.
