Gracey curette #11/12 #7 handle mesial orange

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

The Gracey #11/12 curette offered by the brand Hu-Friedy is a precision instrument intended for periodontology. This device is distinguished by its specific design for the treatment of mesial surfaces of posterior teeth (premolars and molars). It features a #7 type handle, orange in color, facilitating visual recognition within the clinical tray. As an instrument in the INSTRU category, it meets the quality requirements for manual root debridement procedures. This model is manufactured by a recognized industry player, ensuring compliance with professional standards for dental surgery and periodontal hygiene.

What are the clinical indications for this periodontal mesial curette?

The use of this dental mesial curette is indicated for the non-surgical treatment of periodontal diseases, particularly during scaling and root planing (mesial planing). It is specifically adapted to access the mesial areas of posterior sectors where the angulation of universal curettes might be insufficient. Clinicians use this Hu-Friedy brand instrument to remove deep subgingival calculus and debride altered cementum in periodontal pockets. Its application is essential for restoring gingival health and promoting epithelial reattachment during initial or supportive periodontal therapies.

What are the technical characteristics of this instrument?

The Gracey #11/12 curette from the brand Hu-Friedy features precise angulation of its working part, optimized for mesial surfaces. Unlike universal curettes, it has a single cutting edge per end, tilted at 70 degrees relative to the terminal shank. This technical specificity allows for atraumatic insertion into the sulcus and maximum cutting efficiency during the pulling stroke. The orange #7 handle offers a grip adapted to the requirements of repetitive movements in periodontics. This device is classified as a Class I instrument, meeting safety standards for non-invasive or short-term invasive medical devices used by professionals.

What are the contraindications for the use of this device?

According to the information provided by the manufacturer, specific contraindications are not listed beyond use being reserved exclusively for qualified healthcare professionals. However, standard clinical protocols in periodontology should be followed. The use of this mesial curette should be avoided on fragile prosthetic surfaces or implants without specific precautions (use of dedicated implant curettes if necessary) to avoid scratching the surfaces. The practitioner must assess the state of soft and hard tissues before any intervention. As indicated in the instructions, this Class I medical device requires careful reading of the instructions before use to ensure patient safety.

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

As a reusable and non-resorbable metallic instrument, the Gracey #11/12 curette must follow a strict sterilization protocol between each patient. Although composition details are not specified, this type of Hu-Friedy brand instrument requires a pre-disinfection cleaning, followed by autoclaving according to the cycles validated by the manufacturer. It is imperative to check the integrity of the mesial curette's cutting edge before each use. Regular sharpening with appropriate stones is essential to maintain cutting efficiency and avoid traumatizing periodontal tissues through excessive pressure caused by a dull blade.

Who is the manufacturer and what standards are respected?

The official manufacturer of this instrument is Hu-friedy, located at 3232 N. Rockwell St. Chicago, Il 60618 USA. This product is a Class I medical device, meaning it meets the basic regulatory requirements for manual surgical instruments.
