Cleoid-discoid carver #89/92 #6 handle - Hu-Friedy - Delynov

What is the cleoid-discoid carver #89/92?

The cleoid-discoid carver #89/92 is a precision manual instrument manufactured by Hu-Friedy, a recognized manufacturer in the field of surgical and dental instrumentation. This device consists of a double working end mounted on a #6 handle. Its structure is specifically designed for working with restorative materials. The discoid end has a flat circular shape, while the cleoid end adopts a claw or pointed leaf shape. This instrument is a classic of restorative instrumentation, allowing practitioners to manipulate materials with great finesse before their complete hardening.

What are the clinical indications for this instrument?

The cleoid-discoid carver is primarily indicated for carving amalgams and composites during direct restoration phases. In conservative surgery, it is used to recreate the functional anatomy of occlusal surfaces. The discoid part allows for roughing the surface and removing excess material on the cavity margins. The cleoid part, thanks to its tapered tip, is used to engrave secondary grooves and deepen pits, thus ensuring an occlusal morphology close to the natural tooth. Its use is essential to guarantee correct occlusion and avoid post-operative high spots.

What are the technical characteristics of the #6 handle?

The cleoid-discoid carver #89/92 uses the Hu-Friedy #6 handle. This handle is distinguished by a specific diameter designed to provide a stable grip during the translation and rotation movements necessary for carving materials. Unlike thinner handles, the #6 handle allows for controlled force transmission while limiting muscle fatigue during prolonged procedures. The junction between the handle and the #89 and #92 working ends is made according to the rigorous quality standards of Hu-Friedy Mfg. Co., LLC, ensuring the durability of the instrument during cleaning and sterilization cycles.

What are the contraindications for the use of this instrument?

According to the information provided by the manufacturer Hu-Friedy, the use of this instrument is strictly reserved for qualified healthcare professionals. There are no specific medical contraindications listed in the raw technical documentation, other than the usual precautions for use related to manual instrumentation. This instrument should not be used on structures for which it was not designed, such as prying on bone elements or rigid prosthetic elements, which could damage the working ends. The practitioner must systematically inspect the instrument before use to detect any signs of wear or deformation.

What are the maintenance precautions for this Hu-Friedy device?

Although specific sterilization details are not provided in the raw text, Hu-Friedy Class I instruments must be processed according to standard dental office hygiene protocols. It is imperative to read the instructions carefully before use to comply with the decontamination and sterilization cycles recommended by the manufacturer. As a non-absorbable and reusable instrument, meticulous cleaning of the cleoid and discoid ends is necessary to remove any restorative material residue (composite or amalgam) before autoclaving, in order to preserve the integrity of the cutting edge and the metal surface.

Who is the manufacturer and what standards are met?

This medical device is manufactured by Hu-Friedy Mfg. Co., LLC, located at 3232 N. Rockwell St. Chicago, Il 60618 USA. The cleoid-discoid carver #89/92 is classified as a Class I medical device. As such, it meets the safety and performance requirements applicable to this category of instruments. The manufacturer emphasizes that the use of this equipment is reserved exclusively for healthcare professionals. Compliance with the protocols described in the instructions for use is essential to guarantee patient safety and the longevity of the instrumentation within the clinic.
