Orthodontic bracket positioning tweezers, rear end for angulation adjustment - Helmut Zepf (31.299.01) - Delynov

What is the Helmut Zepf bracket positioning tweezer?

The orthodontic bracket positioning tweezer, referenced under code 31.299.01, is a specialized manual instrument developed by Helmut Zepf Medizintechnik GmbH. This device is distinguished by a bifunctional structure: a prehensile part at the front for handling attachments and a rigid rear end dedicated to angulation adjustment. It is designed to offer a stable grip and delicate handling of small orthodontic components, meeting the requirements of clinicians during indirect or direct bonding phases.

What are the clinical indications for this instrument?

This bracket tweezer finds its main application during bonding procedures for multi-attachment devices in orthodontics. It is indicated for the secure transfer of the bracket from the technical tray to the buccal or lingual surface of the tooth. Its secondary function, located at the opposite end of the jaws, allows for micro-adjustments of the bracket's long axis relative to the crown axis of the tooth, thus ensuring compliance with the established orthodontic treatment plan.

What are the technical characteristics of reference 31.299.01?

The Helmut Zepf tweezer (31.299.01) features specific characteristics for clinical orthodontics. It has fine, calibrated jaws to maintain constant pressure on the bracket without risking deformation or marking of its surface. The distinctive technical element is its rear end, shaped to serve as a precision lever or pusher, facilitating the pivoting of the attachment on the resin film. Its monobloc design ensures direct transmission of force for optimal tactile control.

What are the contraindications for the use of this orthodontic positioning plier?

There are no specific documented clinical contraindications for the use of this bracket placement plier outside of standard asepsis protocols. However, this instrument must not be used for bending heavy-gauge wires or for removing cemented bands, as this could damage the alignment of the jaws or the rear adjustment end. Use must remain strictly limited to the positioning and adjustment of orthodontic brackets.

What are the maintenance precautions for this Helmut Zepf device?

Like all surgical and orthodontic instruments produced by Helmut Zepf Medizintechnik GmbH, this tweezer must follow a strict cycle of decontamination, cleaning, and sterilization between each patient. It is recommended to use neutral pH cleaning solutions to preserve the metal surface finish. Particular attention must be paid to the joint and the ends to avoid the accumulation of bonding composite residues, which could compromise positioning precision during subsequent uses.

Who is the manufacturer and what standards are respected?

The official manufacturer is Helmut Zepf Medizintechnik GmbH, a company recognized for the quality of its surgical and orthodontic instruments. Although the specific regulatory class and CE marking are not detailed in the current technical data, Helmut Zepf products are manufactured according to rigorous industrial standards specific to reusable medical devices. Practitioners are invited to refer to the instructions for use and the markings on the packaging to verify regulatory compliance before use.
