Forest Ø 0.8MM Drilling Depth 9MM, SHAFT RA (08.523.08) - Helmut ZEPF - Delynov

What is the Helmut Zepf Ø 0.8MM drill?

The Helmut Zepf Ø 0.8MM drill, referenced under code 08.523.08, is a precision rotary instrument designed for bone surgery. This dental drill features a fixed drilling depth of 9MM and uses a SHAFT RA (Right Angle) type connection, compatible with standard contra-angles. Manufactured by Helmut Zepf Medizintechnik GmbH, this device is made of medical stainless steel, a material chosen for its mechanical properties during osteotomy. It is a non-sterile instrument that requires a full cycle of cleaning, disinfection, and sterilization before its first use and between each patient, in accordance with the reprocessing protocols in force in dental practices.

What are the clinical indications for this dental drilling bur?

This dental drilling bur is primarily indicated for the initial stages of implant site preparation or for the fixation of osteosynthesis screws. In implantology, it is used to perform precise pre-drilling of 0.8MM in diameter, allowing for the guidance of larger diameter drills or marking the exact location of the future implant on the alveolar ridge. Its 9MM depth is suitable for procedures requiring strict control of bone penetration to avoid sensitive anatomical structures. It is used by dental surgeons and implantologists during pre-implant surgeries, implant placements, or guided bone regeneration procedures requiring cortical anchorage.

What are the technical characteristics of this implant drill?

The Helmut Zepf implant drill (reference 08.523.08) is defined by rigorous geometric specifications: a cutting diameter of 0.8MM and a working part allowing for a drilling depth of 9MM. The SHAFT RA fixation system ensures stable transmission of motor torque via the contra-angle. Manufactured in medical stainless steel by Helmut Zepf Medizintechnik GmbH, the instrument must undergo a thorough visual inspection before each use to detect potential damage such as cracks, breaks, or wear of the cutting edges. The use of a blunt or damaged instrument is prohibited to guarantee cutting efficiency and limit thermal heating of the bone.

What are the contraindications for the use of this dental drill?

The main contraindication mentioned by the manufacturer Helmut Zepf concerns known hypersensitivity or intolerance to metals. As the instrument is manufactured from medical stainless steel, contact with the patient may trigger an allergic reaction in sensitive individuals. If such a reaction occurs during the procedure, the process must be immediately interrupted and necessary medical measures must be taken. Furthermore, the use of this drill is strictly reserved for qualified healthcare professionals. It must never be used if it shows visible signs of wear or defects on the cutting edges, as this would compromise the safety of the surgical act.

What are the maintenance and sterilization precautions?

The dental bone drilling bur is delivered non-sterile. It is imperative to carry out complete cleaning, disinfection, and sterilization before the first use, as well as after each clinical cycle. Due to its design and the materials used, there is no defined maximum limit for treatment cycles, but the lifespan depends on mechanical wear. The practitioner must verify compatibility with other products used simultaneously. Rigorous cleaning is essential to remove bone debris from the flutes before autoclaving. The use of damaged, cracked products or those with blunt edges is strictly forbidden to maintain drilling precision.

Who is the manufacturer and what standards are respected?

This medical device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. This product belongs to Class I according to the regulatory classification of medical devices. As a manual dental instrument intended for use by healthcare professionals, it meets the safety and performance requirements defined by the manufacturer. Compliance with cleaning and sterilization protocols is the responsibility of the practitioner to ensure conformity with hospital hygiene standards. Traceability is ensured by the technical reference 08.523.08, specific to this 0.8MM diameter drill model.
