KREKELER Caliper - Helmut Zepf (31.693.10)

What is the Helmut Zepf Prof. KREKELER Caliper?

The Prof. KREKELER Caliper, referenced under code 31.693.10, is a manual measuring instrument developed by the manufacturer Helmut Zepf Medizintechnik GmbH. This precision tool is specifically structured to meet the requirements of oral surgery. Its design allows the practitioner to obtain reliable linear measurements directly in the mouth or on study models. As a dental measuring instrument, it consists of a graduated scale and measuring jaws adapted to the restricted spaces of the oral cavity. Its manufacture by Helmut Zepf guarantees a rigorous adjustment of the moving components, thus ensuring a stable and repeatable reading of the clinical dimensions necessary for diagnosis or the execution of the surgical act.

What are the clinical indications for this surgical caliper?

This surgical caliper finds its primary indications in oral surgery, periodontology, and implantology procedures. In implantology, it is used to measure the mesio-distal space available between two teeth bordering an edentulous area, or to evaluate the thickness of the alveolar bone before implant placement or bone grafting. In periodontal surgery, this implant measuring instrument allows for the quantification of recessions or soft tissue dimensions. It is also useful for checking the dimensions of bone blocks during autogenous harvesting or for calibrating rotary instruments. Its versatility makes it an essential tool for securing safety distances relative to sensitive anatomical structures such as the inferior alveolar nerve or the maxillary sinus.

What are the technical characteristics of model 31.693.10?

Model 31.693.10 is distinguished by its specific configuration known as Prof. KREKELER. Unlike standard industrial calipers, this dental measuring instrument has ergonomics adapted for intraoral handling. It features a precise graduation scale allowing for rapid reading in millimeters. The measuring jaws are designed to access difficult-to-reach posterior areas while minimizing bulk. The surface finish is designed to limit reflections under the operating light, thus optimizing the visibility of the measurement for the surgeon. The sliding mechanism is adjusted to provide fluid resistance, preventing any accidental slippage when taking measurements in a wet environment.

What are the contraindications for using this instrument?

There are no absolute medical contraindications related to the intrinsic use of a surgical caliper. However, its use is discouraged in situations where the patient's mouth opening is too limited to allow safe access without risk of trauma to the peripheral soft tissues. Furthermore, this instrument must not be used if it shows visible signs of deformation or wear on the graduation, which would distort clinical measurements and could lead to a surgical planning error. As with any reusable instrument, sterilization not complying with the Helmut Zepf manufacturer protocols constitutes a major contraindication to its use at the operative site to avoid any risk of cross-contamination.

What are the maintenance precautions for this non-absorbable equipment?

As a non-absorbable metallic instrument, the Prof. KREKELER caliper requires a rigorous maintenance protocol to maintain its metric precision. After each use, it must be decontaminated, cleaned, and sterilized according to the validated cycles for surgical instrumentation. It is imperative to check for the absence of organic residues in the sliding mechanism, as the accumulation of debris could hinder the mobility of the jaws or corrode the steel over the long term. Storage must be in a dry environment. It is recommended to handle the instrument with care to avoid drops that could distort the alignment of the measuring jaws, thus rendering the implant measuring instrument unfit for precise clinical use.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a company recognized in the high-quality surgical instrumentation sector. Manufacturing follows strict industrial processes to guarantee compliance with the precision requirements expected in the medical field. Although detailed regulatory specifications (class or specific CE marking) are not mentioned in the source data, Helmut Zepf products are designed to meet the safety and performance standards in force for reusable instrumentation. The practitioner is invited to systematically refer to the instructions for use and the manufacturer's technical catalog to confirm the sterilization protocols and specific certifications applicable to reference code 31.693.10.
