Splitter NiTi Num MA57 Handle Num 7 Yellow Diameter 20 - Hu-Friedy - Delynov

What is the Hu-Friedy NiTi Spreader #MA57?

The NiTi Spreader #MA57 is a manual endodontic instrument developed by Hu-Friedy. It is distinguished by its Nickel-Titanium (NiTi) structure, an alloy recognized for its high flexibility and shape memory. This niti lateral spreader features a yellow number 7 handle and a diameter of 20. Its design allows for precise handling during critical phases of root canal obturation. Unlike stainless steel instruments, its NiTi composition allows it to follow canal curvatures with increased efficiency, thereby reducing the risks of apical transport or deformation of the initial canal trajectory.

What are the clinical indications for this niti endodontic spreader?

This device is specifically indicated for endodontic procedures, more precisely for the lateral condensation technique of gutta-percha. In restorative dental surgery, the NiTi Spreader #MA57 is used to compact the master cone against the canal walls to free up space for accessory gutta-percha cones. Its use is particularly relevant in narrow canals or those presenting marked curvatures where the rigidity of a standard spreader could be limiting. It ensures a homogeneous obturation density, essential for guaranteeing apical seal and the long-term therapeutic success of endodontic treatments.

What are the technical characteristics of the NiTi Spreader #MA57?

The NiTi Spreader #MA57 presents precise technical specifications to meet the requirements of practitioners. It features a Nickel-Titanium working part with a diameter of 20, offering a balance between fineness and torsional resistance. The #7 type handle, identified by its yellow color code, ensures a stable grip and rapid identification within the clinical tray. The inherent flexibility of NiTi allows this instrument to adapt to anatomical variations of the canal system without exerting excessive pressure on the dentinal walls. This device is designed to withstand standard cleaning and sterilization cycles in the dental office.

What are the contraindications for the use of this instrument?

The specific contraindications mentioned by the manufacturer Hu-Friedy Mfg. Co., LLC primarily concern adherence to the professional framework. The use of this spreader is strictly reserved for healthcare professionals qualified in odontology. Although the source text does not list medical contraindications related to systemic pathologies, it is imperative to refer to the instructions for use before any intervention. As with any endodontic instrument, its use may be contraindicated in clinical situations where canal access is impossible or if the patient presents a known hypersensitivity to the components of the Nickel-Titanium alloy.

What are the precautions for use and maintenance for this non-resorbable device?

As a non-resorbable metallic instrument, the NiTi Spreader #MA57 requires a rigorous maintenance protocol. Before each use, the practitioner must perform a meticulous visual inspection to detect any signs of metal fatigue, deformed flutes, or corrosion. Although NiTi is extremely resistant, intensive use can lead to instrumental fracture if torsional limits are exceeded. It is essential to read the instructions carefully to respect the sterilization cycles recommended by Hu-Friedy. Adequate cleaning after each procedure is crucial to maintain the mechanical properties of the instrument and ensure the aseptic safety of the patient.

Who is the manufacturer and what standards are respected by this product?

The NiTi Spreader #MA57 is manufactured by Hu-Friedy Mfg. Co., LLC, headquartered in Chicago, USA. This manufacturer is globally recognized for the quality of its surgical and endodontic instrumentation. This product is classified as a Class I medical device according to current regulations.
