Nickel Titanium hand cone file, NiTi Protaper File for Hand

     Product Description

Nickel titanium hand cone file, commonly known as hand vertebrae, is a specialized manual instrument for dental pulp and root canal treatment.

Made of nickel titanium alloy and designed with a large taper angle, it relies on manual pulling and rotating operations by doctors for root canal dredging, enlargement, and shaping, compensating for the disadvantage of stainless steel files being too hard and easy to penetrate on the side.Root canal file, Handheld instruments made of metal materials such as stainless steel and nickel titanium alloy, with engraved or spiral edges on the working end for cutting and leveling purposes. They are passive products and not sterile. Used for cutting, smoothing, cleaning, and shaping dental bones and root canals in dental root canal treatment.

NiTi Material, With progressive taper, With crown down techniq, Special designed for difficult highly calcified canal and serverly carved root canals. Niti material, Superelastic and Flexible, NiTi protaper Files have two types for machine and hand use, with lengths of 21mm and 25mm, and six models available. This is one of our dental consumables products.

Product Specifications

Main Function

•  earing narrow, curved, and small calcified root canals;

• anually expand the root canal, adjust the shape of the root  canal, and form a smooth cone shape;

• emove the decay and infected dentin from the inner wall of the root canal;

•  in root canal flushing and preparation, creating conditions for root canal filling.

Product advantages

•  Good flexibility, suitable for bending root canals, reducing steps, lateral penetration, and root tip deviation;

• Manual operation, no need for motor expansion, simple operation, low cost;

• The large taper cutting force is strong, and the forming effect is better than ordinary hand stainless steel K files and H files;

•  Good elasticity, not easily deformed or broken, and higher clinical safety.
