MECHANICAL GLIDE PATH &
PREFLARING
Slide 3
PREFLARING & GLIDE PATH– DEFINITION
Preflaring is the preliminary root canal enlargement needed to
reduce the risk of taper lock of the tip of the first rotary instrument
used to shape the canal.
Glide Path is obtained during preflaring and corresponds to the
smooth canal preparation that rotary instruments can follow
without the risk of blockage or bending.
Until now, this stage is conventionally performed with hand SST
instruments, such as K-Files 008, 010 or 015.
Slide 4
PREFLARING & GLIDE PATH– IMPORTANCE
Study conclusions
By creating a canal (a Glide Path) at least as large as the diameter
of the NiTi rotary instrument that will be used successively (and
which has a greater taper), drastically reduces the torsional stress
and, therefore, the risk of file separation.
Slide 5
PREFLARING & GLIDE PATH– IMPORTANCE
Glide Path is an essential step:
-
to fully understand and appreciate the anatomy of the canal to
be treated (i.e. mentally develop a three dimensional image of
the canal system to shape)
-
to reduce the risk of rotary instrument breakage
Slide 6
MANUAL PREFLARING – PROBLEMS
The initial preflaring and glide path are normally carried out with
stainless steel hand files.
Because of the relative stiffness of these instruments, it can be
difficult to avoid the risk of:
- canal transportation
→ may lead, in severe cases, to root canal perforation
Slide 7
MANUAL PREFLARING – PROBLEMS
Because of the relative stiffness of these instruments, it can be
difficult to avoid the risk of:
- ledges
→ the tip could block in the canal and, if not withdrawn but
pushed apically, could eventually break
- apical zip
→ may lead to obturation difficulties
Slide 8
PREFLARING & GLIDE PATH – NEW SOLUTION
PathFile™, a new rotary Nickel-Titanium solution for Mechanical
Glide Path and Preflaring
A new range available in 3 ISO sizes (013, 016 and 019) and 3
lengths (21, 25 and 31mm).
Flexible and resistant to cyclic fatigue, they offer many advantages
compared to manual solutions.
Slide 9
PATHFILE™ – STANDARD SEQUENCE
Scout and negotiation with a standard K-File #010 until it can
move smoothly along the canal
With same file, working length determination in combination with
an Apex locator
PathFile™ #013 to working length
PathFile™ #016 to working length
PathFile™ #019 to working length
Canal shaping with any NiTi rotary system
Slide 10
PATHFILE™ – OTHER SEQUENCES
LARGE AND EASY CANALS
If it is possible to reach the full working length with a K-File #020,
the Glide Path is not necessary and no PathFile™ will therefore
have to be used.
Slide 11
PATHFILE™ – OTHER SEQUENCES
“INTERMEDIATE” CANALS
If the user feels, during the initial scouting with the K-File 010, that
the canal is rather wide, the recommendation is to use either
PathFile™ 016 and 019 or even only PathFile™ 019.
Slide 12
PATHFILE™ – OTHER SEQUENCES
THIN, CUVED, CALCIFIED CANALS
In these cases the standard sequence is recommended, i.e.
PathFile™ 013, 016 and 019
Slide 13
PATHFILE™ – DIRECTIONS FOR USE
Rotation speed ≈ 300 rpm
Instruments should be used with a delicate in/out movement until
they reach the full length. Strong axial forces should therefore be
avoided.
Time needed to reach working length normally does not exceed 35 seconds/file
The rotating motion will carry debris in a coronal direction
Slide 14
FEATURES AND BENEFITS
Development in collaboration with Prof Berutti,
Prof Cantatore and Dr Castellucci
support of 3 internationally renowned Opinion Leaders as well
as of the Dentsply Maillefer OPL network
quality evidence thanks to their expertise
Slide 15
PATHFILE™ – FEATURES & BENEFITS
NiTi – Square Section – 2% Taper
high strength against cyclic fatigue
flexibility
Tip diameters (013-016-019)
gradual increase that facilitates the progression of the files
without the need for strong axial pressure
Slide 16
PATHFILE™ – FEATURES & BENEFITS
Tip design (transition angle reduction)
Reduced risk of ledges and canal transportation
PathFile™
K-File
Slide 17
PATHFILE™ – STUDY CONCLUSION
The study carried out by Prof Berutti, Prof Cantatore and Dr
Castellucci clearly shows that, when compared to manual
instruments, PathFile™:
1. better maintains the original canal anatomy
→ less canal transportation and canal aberrations
2. is more forgiving procedural errors such as incorrect working
length
→ no apical transport when WL is too long
→ no ledges when WL is too short
Slide 18
PATHFILE™ – STUDY CONCLUSION
The study carried out by Prof Berutti, Prof Cantatore and Dr
Castellucci clearly shows that, when compared to manual
instruments, PathFile™:
3. reduces the instrumentation time needed
4. allows General Dental Practitioners to obtain similar results to
those achieved by endodontists
