NiTi Spreader #25 handle #7 red diam.25

What is the NiTi Spreader #25 handle #7 red diam.25?

The NiTi Spreader #25 from the brand Hu-Friedy is a manual instrument specific to endodontics, used for cold lateral condensation of obturation materials. Unlike stainless steel models, this device is manufactured from Nickel-Titanium (NiTi), an alloy recognized for its shape memory and high flexibility. It features a diameter of 25 and is mounted on a red number 7 handle, facilitating its identification within the technical tray. This instrument allows the practitioner to exert controlled lateral pressure inside the root canal to ensure optimal sealing of the final obturation.

What are the clinical indications?

This device from the brand Hu-Friedy is indicated for endodontic treatment procedures, specifically during the obturation stage of the root canal system. Its primary use lies in the lateral condensation technique, where it serves to displace the master gutta-percha cone to free up space for secondary cones. Thanks to its NiTi composition, it is particularly suitable for canals presenting pronounced anatomical curvatures, thereby reducing the risks of canal transport or ledge formation compared to rigid instruments. It is exclusively intended for qualified healthcare professionals practicing dental surgery and endodontics.

What are the technical characteristics?

The NiTi Spreader #25 is distinguished by its metallurgical properties related to Nickel-Titanium. Its fine tip with a diameter of 25 allows for deep penetration into the canal preparation, even in narrow apical zones. The number 7 handle is designed to provide a stable grip during compaction movements. The red color code corresponds to sizing standards for immediate identification. As a Class I product, this instrument meets the basic regulatory requirements for non-invasive or invasive medical devices for temporary use. Its intrinsic flexibility allows it to follow the natural trajectory of the canal without exerting excessive force on the root walls.

What are the contraindications for use?

According to the information provided by the manufacturer Hu-friedy, the use of this device is strictly reserved for healthcare professionals. Although specific contraindications are not detailed in the raw documentation, standard endodontic principles apply: the instrument must not be used if the practitioner cannot guarantee secure access to the canal or if the root anatomy presents risks of imminent instrumental fracture. It is imperative to read the instructions carefully before use to become familiar with all safety warnings. Like any precision instrument from the brand Hu-Friedy, a prior visual examination is recommended to detect any signs of wear or metal fatigue.

What are the precautions for use and maintenance?

As the NiTi Spreader #25 is a non-resorbable instrument, it requires a rigorous cleaning and sterilization protocol between each patient, in accordance with the directives of the manufacturer Hu-friedy located in Chicago. The practitioner must ensure not to apply excessive torsional forces, as NiTi, although flexible, can undergo cyclic fatigue. It is advisable to check the integrity of the flutes and the tip before each canal insertion. Storage must be in a dry and clean environment. Handling by expert hands is required to avoid any root perforation, particularly when applying the lateral pressure necessary for the condensation of obturation materials.

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. Compliance with this classification ensures that the instrument meets the safety and performance standards defined for this category of surgical and dental equipment.
