Gracey curette #11/12 handle #7 AF mesial orange

What is the Gracey #11/12 curette #7 AF handle mesial orange?

The Gracey #11/12 curette from the Hu-Friedy brand is a specific periodontal instrumentation instrument, belonging to the INSTRU category. This medical device is distinguished by its #7 AF handle and its orange color code, facilitating its identification within the clinical tray. Unlike universal curettes, this model features an angled blade with only one sharp edge, allowing precise work on root surfaces without damaging adjacent soft tissues. It is manufactured under the supervision of the manufacturer Hu-friedy, a recognized player in the field of surgical instrumentation. This model is specifically configured to treat the mesial areas of posterior teeth, offering optimal angulation for the removal of subgingival calculus and root polishing.

What are the clinical indications?

The use of this curette from the Hu-Friedy brand is mainly indicated in periodontology for the treatment of mesial surfaces of molars and premolars. It is used during periodontal debridement phases, aiming to eliminate calcified calculus deposits and bacterial biofilm located in deep periodontal pockets. In oral and implant surgery, this instrument can also be used to clean exposed root surfaces during debridement flaps. Its use is strictly reserved for qualified healthcare professionals, in accordance with the manufacturer's directives. It allows for selective curettage action, essential for promoting epithelial reattachment and the reduction of gingival inflammation in patients with chronic or aggressive periodontitis.

What are the technical characteristics?

Technically, the Gracey #11/12 curette is characterized by a precise angulation of its shank, designed to follow the anatomy of the mesial surfaces of posterior teeth. The #7 AF type handle offers a grip adapted to the requirements of daily clinical practice. As a Class I device, this instrument meets the basic regulatory requirements for non-invasive or short-term invasive medical devices. The working part is specifically sharpened on one side only, which defines the working technique: the face of the blade is tilted at 70 degrees relative to the terminal shank. This technical specificity ensures that only the lower cutting edge is in contact with the root, thus protecting the junctional epithelium during the passage of the instrument.

What are the contraindications for use?

Specific contraindications mentioned by the manufacturer Hu-friedy indicate that the use of this instrument is strictly reserved for healthcare professionals. Although the raw MDR text does not list systemic pathologies as direct contraindications, the use of this instrument from the Hu-Friedy brand should be avoided on fragile prosthetic surfaces or implants if the material is not compatible, in order to avoid any scratching or metallic contamination. The instructions for use should always be consulted before use to verify the suitability of the instrument with the patient's clinical condition. Thorough knowledge of periodontal anatomy is required to avoid any trauma to the supporting tissues or excessive alteration of the root cementum during planing.

What are the maintenance and durability precautions?

As a non-resorbable instrument in the INSTRU category, its durability directly depends on the sterilization and maintenance protocols followed by the practice. Although the exact composition is not specified, this type of Class I instrument requires rigorous cleaning after each intervention to remove organic debris. It is imperative to follow the cleaning and sterilization instructions provided by the manufacturer Hu-friedy located in Chicago. Regular sharpening of the blade is necessary to maintain cutting efficiency, while ensuring the original 70-degree angle is respected. A visual inspection before each use is recommended to detect any excessive wear or deformation of the shank, thus guaranteeing patient safety and the precision of the surgical movement.

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, in accordance with current regulations. Compliance with rigorous manufacturing protocols by the manufacturer ensures the instrument's conformity with the standards expected by dental surgery professionals. It is reminded that careful reading of the instructions is mandatory before any use. The Hu-Friedy brand guarantees that this instrument is intended exclusively for professional use in a clinical setting. Although the CE marking is not explicitly detailed in the source data, the Class I classification confirms its regulated status on the medical device market.
