Case of premature obturation with titanic titanium which sunk in the MB canal
- took a little cajoling to retrieve this "shorty" 2.5 some mm. of an
instrument which obstructed my mission to apical city! Rest all was fun as
usual! - Rajiv Patel
Great case! Congratulations. How did you manage to remove de fragment?
Magnification? Ultrasonics? any specific device IRS, Remove All Kit,
Spriggs technique? Why did it fracture? Cyclic? Torsional stress?
Dentin preservention is great. Very nice case. I find really difficult
to work inside mesial canals in lower molars with the scope. - Javier Pascual
Hi Javier, Thank you for your comments.
I did use a microscope to remove the SI.
Used a combination of gates and ultrasonics to expose the head of the instrument.
If you can't see it you can't do it. I use alcohol + EDTA to keep flushing the
debris around the instrument to get a sense of the direction the canal follows
and according make attempts to trough around it.
I use my favorite work horse for SI's - UT4 from www.eie2.com to trough around
the instrument and out comes shorty!....wish it happened easily...(;
Don't forget to plug the other orifices with sponge or cotton, otherwise you
just might get more practice removing SI's.
I did not separate "this" instrument, but my forensic suspicion at the scene
of the crime is that it happened because of the lack of a glyde path prior to
using the NiTi rotary in the canal led to the premature obturation. And you
are absolutely right about need to aware of the limited M- D width of lower
molars - not much room to work with...before you enter Perf city.- Rajiv
