NiTi Spreader #40 handle #7 black diam.40

What is the NiTi Spreader #40 handle #7 black diam.40?

The NiTi Spreader #40, marketed under the brand Hu-Friedy, is a manual instrument specific to endodontics. Its structure consists of a Nickel-Titanium (NiTi) active part with a diameter of 40, mounted on a number 7 handle in black for quick visual identification. Unlike steel models, the use of NiTi by the manufacturer Hu-friedy gives this instrument increased flexibility, allowing it to follow the anatomical curvatures of the root canals during condensation phases. This device belongs to the consumables category (CONSO) and is strictly reserved for professional use in dental practices.

What are the clinical indications?

This device is indicated for performing root canal obturations using the lateral condensation technique. As an endo lateral plugger, it is used after the shaping and cleaning of the canal system. Its clinical role is to compact the master gutta-percha against the canal walls to release space for secondary cones. The use of the Hu-Friedy NiTi Spreader #40 is particularly relevant in canals with marked curvatures where the material's flexibility reduces the risk of mechanical stress on the root structure. It thus ensures optimal apical sealing through homogeneous compression of the filling material.

What are the technical characteristics?

The NiTi Spreader #40 presents precise technical specifications to meet the requirements of modern endodontics. It has a diameter of 40 at the tip, corresponding to canal preparation standards. Its main characteristic lies in its Nickel-Titanium alloy composition, offering shape memory and superior flexibility compared to stainless steel. The black #7 handle ensures a grip adapted to the rotation and pressure movements necessary for condensation. This Hu-Friedy product is manufactured by Hu-friedy in the USA, guaranteeing a controlled manufacturing process for Class I medical devices.

What are the contraindications for use?

According to the information provided by the manufacturer Hu-friedy, specific contraindications are not detailed beyond general warnings for use. However, the use of this instrument is strictly reserved for qualified healthcare professionals mastering endodontic techniques. Current sterilization and asepsis protocols for any intracanal medical device must be respected. A visual inspection of the NiTi active part is recommended before each use to detect any signs of metal fatigue or twisting, in order to prevent risks of instrumental fracture inside the root canal.

What are the precautions for use and maintenance?

As the NiTi Spreader #40 is a non-resorbable and reusable instrument, it requires a rigorous maintenance protocol. As a gutta lateral plugger, it must be cleaned, disinfected, and sterilized before each intervention in accordance with the manufacturer's instructions for use. Practitioners must be careful not to exert excessive apical pressure that could fracture the root or the instrument itself. Although NiTi is extremely flexible, respecting instrumental sequences and the match between the spreader size (diameter 40) and the canal preparation are essential to guarantee treatment safety and the longevity of the clinical result.

Who is the manufacturer and what standards are respected?

The NiTi Spreader #40 is manufactured by the company Hu-friedy, located at 3232 N. Rockwell St. Chicago, Il 60618 USA. This medical device is listed under Class I, meeting the regulatory safety and performance requirements for this category of products. The brand Hu-Friedy ensures the distribution of this instrument intended exclusively for healthcare professionals. It is imperative to read the instructions for use carefully and respect the manufacturer's warnings before any clinical implementation. Although CE marking is not specified in the source data, the product follows the rigorous manufacturing standards imposed by American and international regulations for surgical instruments.
