Surgical screw-in osteotome insert, straight, size 0, conical, Ø 1-2 mm - Helmut Zepf (47.990.10) - Delynov

What is the Helmut Zepf screw-in osteotome insert (47.990.10)?

The surgical screw-in osteotome insert, referenced under code 47.990.10, is a removable instrument designed by the manufacturer Helmut Zepf Medizintechnik GmbH. This device features a straight configuration and a size 0 conical geometry. Its structure is specifically developed to fit onto a compatible insert holder handle, allowing the practitioner to modulate their instrumentation according to the needs of the procedure. This tool is intended for bone surgery procedures where axial precision is paramount. Its robust design meets the requirements of daily clinical practice in implantology and oral surgery.

What are the clinical indications for this straight screw-in osteotome?

This straight screw-in osteotome is primarily indicated in implant site preparation protocols, particularly during bone expansion or condensation of cancellous bone. In implant surgery, it allows for an increase in local bone density through lateral compression, thereby improving the primary stability of the implant in Type III or IV maxillary sectors. It is also used for crestal approach sinus lift techniques, where its conical shape helps in the delicate management of the sinus floor. Its straight configuration makes it particularly suitable for anterior and premolar areas where access is direct.

What are the technical characteristics of this conical insert?

The Helmut Zepf 47.990.10 insert is distinguished by precise technical specifications: it is a size 0 model with an evolving conical shape. The diameter of the working part varies from 1 mm at its distal end to 2 mm at its base. This taper allows for progressive penetration and dilation of bone tissue without material removal, unlike traditional drills. The screw-in connection guarantees perfect integration with the manual instrument, avoiding any mechanical play during the application of pressure or light rotation forces during the surgical phase.

What are the contraindications for the use of this instrument?

Contraindications for the use of this osteotome insert are related to the patient's physiological limits and general principles of oral surgery. Its use is discouraged in cases of excessive bone density (very dense Type I cortical bone) where compression force could lead to micro-fractures or thermal necrosis due to excessive pressure. Furthermore, any uncontrolled systemic pathology affecting bone metabolism or healing constitutes a relative or absolute contraindication. It is the surgeon's responsibility to evaluate the quality of the residual bone volume before undertaking expansion with this instrument.

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

As a reusable surgical instrument made of high-quality stainless steel, this Helmut Zepf insert requires a rigorous decontamination and sterilization protocol after each use. The insert's threading should be carefully cleaned to remove any organic residue that could compromise fixation during the next procedure. Compliance with standard autoclave cycles is imperative to guarantee asepsis. Although the material is designed to resist corrosion, the use of unsuitable cleaning solutions or incomplete drying can alter the surface condition of the surgical osteotome tip over the long term.

Who is the manufacturer and what standards are respected?

The device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-precision dental and surgical instrumentation. As a product distributed by Delynov, this insert meets the industrial manufacturing standards of the Helmut Zepf brand. Although the specific regulatory class and CE marking are not detailed in the current source data, this type of instrument is designed to meet safety and performance requirements in a surgical environment. Practitioners are invited to refer to the manufacturer's technical manual and the instructions for use provided with the product to confirm current certifications.
