What is the cleoid-discoid #89/92 handle #41 - Hu-Friedy?

The cleoid-discoid #89/92 from the Hu-Friedy brand is a manual operative dentistry instrument equipped with a #41 handle. This device consists of two distinct active ends: a claw-shaped tip called a cleoid and a circular disk-shaped end called a discoid. Designed by the manufacturer Hu-Friedy Mfg. Co., LLC, this tool is specifically structured for the manipulation of restorative materials. Its design allows for a stable grip for meticulous finishing work. It is a robust instrument intended for professional use in dental practices or hospital environments, ensuring a response adapted to the requirements of anatomical carving during direct restoration procedures.

What are the clinical indications for the cleoid discoid?

The use of the cleoid discoid is primarily indicated during the carving and modeling phases of dental restorations, particularly for amalgams or composite resins before their complete hardening. In conservative surgery, it allows the practitioner to recreate the natural occlusal anatomy of the tooth. The discoid part is used to remove excess restorative material and to flatten surfaces, while the cleoid tip is ideal for engraving occlusal pits and grooves. This Hu-Friedy instrument is therefore essential for ensuring functional occlusion and precise dental morphology after caries removal and cavity filling.

What are the technical characteristics of this instrument?

The cleoid-discoid #89/92 is characterized by its double functional end mounted on an ergonomic #41 type handle, manufactured by Hu-Friedy. The technical reference #89/92 defines the specific curvature and size of the working parts. The discoid part features a circular sharp edge allowing for controlled material removal, while the cleoid part offers a tapered tip for precision work in narrow areas. As a Class I medical device, this instrument meets the rigorous manufacturing standards of Hu-Friedy Mfg. Co., LLC, ensuring adequate resistance to sterilization cycles and longevity in line with the expectations of healthcare professionals.

What are the contraindications for the use of this device?

According to the information provided by the manufacturer Hu-Friedy Mfg. Co., LLC, the use of this instrument is strictly reserved for qualified healthcare professionals. There are no specific medical contraindications listed other than those related to inappropriate use by untrained personnel or misuse of its primary function of modeling restorative materials. The practitioner must ensure that the instrument is used in accordance with its intended use and must consult the instructions before any use. Any use on anatomical structures not compatible with the shape of the #89/92 ends must be avoided to prevent any iatrogenic risk.

What are the maintenance precautions for this non-resorbable instrument?

As a reusable and non-resorbable metallic surgical instrument, the Hu-Friedy cleoid-discoid requires a rigorous decontamination and sterilization protocol after each patient. Although composition specifics are not detailed here, Hu-Friedy instruments are designed to withstand standard thermal sterilization methods in an autoclave. It is imperative to carefully clean the discoid and cleoid ends to remove any restorative material residue (composite or amalgam) before autoclaving. Compliance with the cleaning instructions from the manufacturer located in Chicago, USA, is crucial for maintaining the integrity of the sharp edges and the performance of the instrument over the long term.
