Mirror number 4 with American thread - 1 piece per package - Hu-Friedy - Delynov

What is the Hu-Friedy #4 American thread mirror?

The #4 American thread mirror is an examination and surgical instrument produced by Hu-Friedy. It comes in the form of a standard #4 size circular mirror head, intended to be screwed onto a compatible handle. This device is specifically equipped with an American-type thread (US thread), which distinguishes it from European thread models (simple stem). Its structure is designed to meet the requirements of clinical practice in oral surgery, providing the reflective surface necessary for visualizing difficult-to-access areas in the oral cavity. This product is packaged in units of one.

What are the clinical indications for this mirror?

This device is indicated for all procedures requiring indirect vision, notably in oral surgery, periodontology, and implantology. The Hu-Friedy #4 mirror is used by practitioners to examine lingual or palatal tooth surfaces, as well as for observing posterior surgical sites. Beyond its reflection function, it serves as a retraction instrument to move the tongue or buccal mucosa, thereby clearing the surgical field. It also facilitates light delivery by reflection to shadowed areas during implant drilling or periodontal debridement phases, ensuring better precision of the technical gesture.

What are the technical characteristics of the product?

The Hu-Friedy #4 mirror is primarily characterized by its American thread connection system. This technical specificity requires the use of a Hu-Friedy handle or a third-party handle strictly respecting American threading standards to ensure stable and secure fixation. The #4 size corresponds to a standard diameter allowing an ideal compromise between an extended field of vision and reduced bulk in the mouth. Manufactured by Hu-Friedy Mfg. Co., LLC, this mirror is designed to withstand the cleaning and sterilization cycles required in a dental office, in accordance with current hygiene protocols for Class I reusable instrumentation.

What are the contraindications for the use of this device?

According to information provided by the manufacturer Hu-Friedy, specific contraindications are not detailed beyond standard protocols related to the use of rotary or manual instruments in the oral environment. However, the use of this mirror is strictly reserved for qualified healthcare professionals. An obvious contraindication would be using the mirror with an incompatible handle (European thread), which could lead to the mirror head detaching during the intervention. The integrity of the reflective surface should be checked before each use; a scratched or pitted mirror must be discarded to avoid any visual failure or accumulation of deposits.

What are the maintenance and handling precautions?

As a non-resorbable and reusable instrument, the Hu-Friedy #4 mirror requires a rigorous decontamination and sterilization protocol after each patient. Although composition specificities are not detailed, this type of Class I instrument must be handled with care to preserve reflection quality. It is imperative to carefully read the instructions for use provided by Hu-Friedy Mfg. Co., LLC before the first use. Practitioners must ensure that the American thread is perfectly clean and free of debris before screwing it onto the handle to avoid any seizing or permanent damage to the thread.

Who is the manufacturer and what standards are respected?

The mirror is manufactured by Hu-Friedy Mfg. Co., LLC, headquartered in Chicago, USA. This medical device is listed as Class I, in accordance with current medical device regulations. As a Class I product, it meets the essential safety and performance requirements defined for non-invasive or invasive manual instruments for temporary use.
