Application
The retreatment file is mainly used for the teeth that have finished root canal treatment, because the infected pulp in the root canal has not been cleaned, and the filling is not tight enough, resulting in re-inflammation and pain in the root canal.
Note: Before treatment, it is necessary to completely remove filling material in the root canal before treatment.
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.
ADVANTAGES AND FEATURES
Easier:
· F3-Q instrument can be used whatever the canal shape
· An easy to remember protocol (colour coded)
Faster:
· High cutting power
More efficient:
· Increased apical taper for better canal cleaning
· 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).
Note: Root canal retreatment is difficult, so it is recommended to use a microscope in clinical practice.
The EDTA lubricant is pushed into the root canal.
During retreatment, the canal was gradually penetrated into the root canal every 1mm, Rinse the root canal with 1%~3% sodium hypochlorite solution and dry the root canal with absorbent paper tip.
