Canule aspiration Pontius - Hu-Friedy

What is the Hu-Friedy #1/2 cleoid-discoid?

The #1/2 cleoid-discoid with #41 handle is a high-precision manual instrument manufactured by Hu-Friedy Mfg. Co., LLC. This device consists of an ergonomic central shaft (#41 handle) and two distinct working ends. The first end, discoid-shaped (similar to a disc), is optimized for removing surplus restorative materials. The second, cleoid-shaped (claw or leaf-shaped), is specifically designed for fine carving of occlusal grooves. This product is part of the brand's INSTRU range, recognized for the quality of its restorative dentistry instruments.

What are the clinical indications for this instrument?

The dental cleoid-discoid is primarily indicated in operative and restorative dentistry procedures. Its use is essential for shaping amalgams or composites before they fully harden. In conservative surgery, it allows the practitioner to carve marginal ridges and recreate functional occlusal morphology. This Hu-Friedy instrument helps ensure perfect marginal adaptation of the restorative material, thereby limiting the risks of over-occlusion or post-operative discomfort for the patient. It is exclusively reserved for use by qualified healthcare professionals.

What are the technical characteristics of the #41 handle?

The #41 handle equipping this Hu-Friedy brand cleoid-discoid is designed to provide a stable grip and optimal tactile control during delicate carving phases. Although specific material details are not provided, the instrument's design meets the rigorous requirements for Class I medical devices. The double-ended structure allows for a rapid transition between the roughing phase (discoid) and the anatomical finishing phase (cleoid), thus optimizing the workflow during direct restorations in the dental office.

What are the contraindications for the use of this device?

According to information provided by the manufacturer Hu-Friedy Mfg. Co., LLC, the use of this instrument is strictly reserved for trained healthcare professionals. There are no specific medical contraindications listed in the technical documentation, other than compliance with standard sterilization and asepsis protocols. The instrument must not be used for applications other than those intended in restorative dentistry, such as prying on bone structures or fixed prostheses, which could damage the fine cleoid-discoid tips.

What are the maintenance and safety precautions?

Like any Class I instrument intended for oral surgery and dentistry, the Hu-Friedy cleoid-discoid requires rigorous maintenance. It is imperative to read the instructions carefully before use to ensure patient safety and the longevity of the tool. Cleaning must be performed immediately after use to prevent the fixation of restorative material residues. Although resorption specifications do not apply here (non-implantable instrument), checking the integrity of the working tips before each procedure is crucial to maintaining the precision of the clinical movement.

Who is the manufacturer and what standards are respected?
