This device belongs to the category of consumables for the maintenance of surgical and prophylaxis equipment in dental practices.

What are the clinical indications for this product?

The use of this conical Arkansas stone is indicated for the regular maintenance of periodontal, oral surgery, and implantology instruments. It is particularly effective for scaler maintenance and the resharpening of Gracey curettes or universal curettes. By maintaining an optimal cutting edge, it allows the practitioner to perform more precise movements during root planing or subgingival scaling, thereby reducing manual fatigue and improving patient comfort during periodontal care.

What are the technical characteristics of the #299 stone?

The Arkansas #299 sharpening stone is distinguished by its conical shape, a geometry essential for treating the internal faces of instruments with curved blades. Manufactured by Hu-Friedy Mfg. Co., LLC, this natural stone offers a fine grit that removes only a minimal amount of metal, thus extending the life of the instruments. Its compact format allows for easy handling for rigorous control of the sharpening angle, ensuring perfect regularity of the cutting edge along the entire length of the treated instrument blade.

What are the contraindications for the use of this stone?

According to the information provided by the manufacturer Hu-Friedy, there are no specific listed medical contraindications for the use of this sharpening stone on instruments. However, its use is strictly reserved for qualified healthcare professionals. It is imperative to follow sharpening protocols so as not to alter the initial morphology of the instruments. Incorrect inclination or excessive pressure could compromise the integrity of the surgical or periodontal instrument, making its clinical use potentially ineffective or dangerous.

What are the maintenance and storage precautions?

To guarantee the longevity of the Arkansas stone, it is recommended to follow the cleaning and lubrication instructions specified by Hu-Friedy. Although this product is classified as non-resorbable (maintenance device), it must be kept clean to avoid the accumulation of metal residues in its pores, which would reduce its abrasive power.

A saturated or damaged stone will no longer allow for the surface finish required for a high-performance surgical instrument.
