Re-treatment files (NiTi) have been specifically designed to remove obturation material from the root canal.
There are three re-treatment files: D1, D2 and D3, one for each third of the canal.
D1 has a cutting tip for effective entrance into the obturation material in the coronal third.
D2 is used in the mid third of the canal
D3 is used in the apical third and have non-active tips that have been designed to closely respect the path of the canal
The tapers of these three files match the diameters of average root canals and the handles are only 11mm long, improving visibility.
Pack: 6 files
