Rubber dam clamp #29 lower premolar

What is the rubber dam clamp #29 lower premolar?

The rubber dam clamp #29 lower premolar from Hu-Friedy is a metallic instrument specifically designed for the isolation of the operative field in dental surgery and endodontics. This device is fixed to the tooth to hold the rubber dam sheet in place, thereby ensuring a dry working area free from salivary contamination. Its structure is adapted to the anatomy of the premolars of the lower arch, offering optimal stability throughout the duration of the intervention. Manufactured according to Hu-Friedy standards, this accessory is a central element of the therapeutic arsenal for practitioners requiring rigorous sealing during their clinical procedures.

What are the clinical indications?

This lower premolar clamp is indicated for all procedures requiring absolute isolation by a dam. It is mainly used during endodontic treatments to prevent the ingestion of instruments or irrigation solutions, as well as in restorative dentistry to guarantee the adhesion of composite materials in a dry environment. Its use is particularly recommended for lower premolars whose morphology requires a firm grip at the cervical level. By keeping the dam taut and stable, it allows the dental surgeon to focus on the technical act while protecting the surrounding soft tissues and improving the visibility of the operative site.

What are the technical characteristics?

The #29 clamp from Hu-Friedy features a robust design adapted to the mechanical stresses of placement under tension. Its shape is specifically calibrated to follow the contour of the lower premolars, thus minimizing the risk of the clamp tipping or jumping during treatment. Although the exact composition is not specified, this type of device is traditionally designed to withstand the repeated sterilization cycles necessary in a dental office. As a Class I product, it meets the basic regulatory requirements for non-invasive medical devices, guaranteeing reliability of use for the practitioner and increased safety for the patient during isolation phases.

What are the contraindications for use?

According to the information provided by the manufacturer Hu-friedy, the use of this device is strictly reserved for qualified healthcare professionals. Contraindications include clinical situations where the supporting tooth has too much coronal decay to allow a stable grip of the clamp, or when the gingival anatomy does not allow positioning without excessive damage to the periodontium. It is necessary to systematically refer to the instructions for use and the manufacturer's warnings to identify any specific restriction related to the patient's health status or potential material incompatibilities before proceeding with the placement of the operative field.

What are the precautions for use for this non-resorbable material?

As it is a non-resorbable metallic instrument, the #29 clamp from Hu-Friedy requires careful handling to avoid any deformation of the jaws which would harm its retention capacity. Before each use, the practitioner must inspect the structural integrity of the device to detect any signs of metal fatigue or corrosion. It is imperative to follow the cleaning, disinfection, and sterilization protocols recommended for Class I devices in order to prevent the risk of cross-contamination. Particular attention must be paid during placement with the clamp forceps so as not to injure the periodontal tissues or damage the dental enamel at the point of contact.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Hu-friedy, located at 3232 N. Rockwell St. Chicago, Il 60618 USA. This product is classified as a Class I medical device, which implies that it meets the safety and performance standards defined for this category of instruments. Hu-Friedy ensures the conformity of the product with the regulatory requirements in force for dentistry accessories. As indicated in the safety information, the use of this clamp is exclusively reserved for healthcare professionals. It is essential to carefully read the instructions provided by the manufacturer before any use to ensure compliance with the recommended clinical and maintenance procedures.
