Dental root apical elevator, figure 77R - Helmut Zepf (17.677.16) - Delynov

What is the Helmut Zepf figure 77R apical elevator?

The dental root apical elevator, model figure 77R, is a specialized manual instrument designed by the manufacturer Helmut Zepf Medizintechnik GmbH. This device, identified under reference 17.677.16, consists of an ergonomic handle and a thin, tapered working part. Its structure is specifically designed to reach narrow apical areas of the socket. As a tool for micro-surgery or conventional extraction surgery, this root apical elevator allows for precise force transmission during the luxation of deep root fragments. Helmut Zepf design quality ensures optimal tactile response for the practitioner during delicate apex release maneuvers.

What are the clinical indications for this instrument?

This apical root elevator is primarily indicated during complex dental extractions where the root has fractured or when the apex remains lodged at the bottom of the socket. In oral and implant surgery, it is used to mobilize root debris without compromising the integrity of the bony alveolar walls, which is crucial for potential immediate or delayed implant placement. Its specific profile, corresponding to figure 77R, allows access to interradicular spaces and difficult-to-reach areas. It is perfectly suited for deep syndesmotomy procedures and the extraction of ankylosed residual roots or those deeply embedded in the maxillary or mandibular bone.

What are the technical characteristics of the 17.677.16 elevator?

The Helmut Zepf dental root apical elevator, reference 17.677.16, is distinguished by its figure 77R configuration. Although exact dimensions are not specified, this model is recognized for its tip fineness allowing precise insertion into the periodontal space. The monobloc design guarantees the rigidity necessary for elevation while preserving the surgeon's tactile sensitivity. The handle is designed to offer a secure grip, limiting the risk of slipping when applying leverage force. This Helmut Zepf instrument is a standardized element for dental surgery trays, meeting the requirements for handling hard and soft tissues in a clinical environment.

What are the contraindications for the use of this elevator?

The use of this root apical elevator is contraindicated in situations where the integrity of adjacent anatomical structures, such as the maxillary sinus or the inferior alveolar canal, could be compromised by excessive pressure. As with any manual surgical instrument, its use is prohibited in patients presenting uncontrolled general contraindications to oral surgery. It must not be used on healthy tissue or stable teeth intended for preservation. Incorrect angulation or disproportionate leverage force can lead to unforeseen bone or root fractures. The practitioner must evaluate bone density and root morphology by radiography before any intervention with this instrument.

What are the maintenance and sterilization precautions?

As a reusable surgical instrument, the Helmut Zepf elevator must follow a strict protocol of cleaning, disinfection, and sterilization after each use. It is recommended to use non-corrosive cleaning solutions and to perform autoclave sterilization according to the manufacturer's standard parameters. Precautions include visual inspection of the working tip to detect any signs of wear, bending, or corrosion that could weaken the instrument or injure the patient. Rigorous maintenance guarantees the longevity of the steel and maintains the mechanical properties necessary for apical elevation. It is imperative to respect drying cycles to avoid any residual oxidation on the instrument surface.

Who is the manufacturer and what standards are met?

The apical elevator figure 77R is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-precision dental instrumentation. Production is subject to quality management protocols specific to medical devices. Although specific certifications (regulatory class or CE marking) are not detailed in the source data provided, Helmut Zepf products are developed to meet the professional requirements of dental surgeons. For any precise information on regulatory compliance or ISO standards specific to reference 17.677.16, please refer to the technical documentation provided by the manufacturer or consult the traceability information available on the product labeling delivered by Delynov.
