1. F3-Q is a retreatment files,used for root canal reteatment,
which can be used 8-10 times repeatedly after high temperature and
high pressure disinfection.
2. F3-Q system proved to be faster than hand instruments in
removing root filling materials.
· Easily cleaning the shards in the canal.
F3-Q Operation Manual
F301902 ,which is a channel file , and is used to establish
straight access to the root canal and play the role of
exploration(300rpm/1.0N)
F3-Q01506 , which is the first treatment file, gradually enlarge
the canal, maintain the apical narrow area, clean the upper part of
the canal, and remove the infectious material(350rpm/2.0N).
F3-Q02007 , which is the second treatment file, gradually enlarged
the canal, maintained the narrow apical area, cleaned the upper
part of the canal again, and removed infectious
material(350rpm/2.0N).
F3-Q02508, which is the third treatment file. The apical diameter
of the root canal was maintained at 0.025mm. The middle and upper
parts of the canal were enlarged to remove the infected
material(350rpm/2.0N).
F3-Q03009,which is the fourth treatment file, The apical diameter
of the root canal was maintained at 0.030mm,enlarging the middle
and upper of canal root to remove the infected material, the
anterior root canal treatment can choose this number(350rpm/2.0N).
