◆ 04 taper, final shape
Minimally invasive concept, better protection of dentin
◆ Challenging complex root canals
When preparing to bend the root canal, the original root canal shape is better maintained, saving time and effort to evenly cut the inner and outer walls of the root canal, following the original root canal anatomy
◆ CM phase a NITI material
1, rotate around the curved axis of the root canal 2, adaptive root canal inherent anatomical structure
◆ Exclusive second blade technology
It makes up for the problem of insufficient cutting force of CM phase nickel-titanium instruments
◆ Smoother passage
Avoid stepping, offset, lateral penetration, or root tip pulling

Order of operation:

Unclog the root canal by hand with a 10, 15 gauge stainless steel K-file.
Use open file (1708), pre-open crown square and middle upper.
Measure the working length with a 10 gauge stainless steel K file and prepare to the root tip with a 15 gauge stainless steel K file.
Machine channel file (1902) to create smooth channels.
Use 2004 (yellow), 2504 (red), 3004 (blue) in turn, in the wash solution soaking, with brush method, every 1-2mm is short lift, ready to the working length.
Every time the file is changed, rinse with a flushing solution (sodium hypochlorite is recommended), and use a No. 10 stainless steel file to return the file. Tip: 'Always' keep 1/3 of the root tip well lubricated without straining.
