Using LA Axxess Bur
1. The LA Axxess Bur should be used in a low-speed latch-type
hand piece at 5,000 – 10,000rpm.
2. Place the tip of the bur in the center of the hollow core. Activate
the hand piece at 5,000 – 10,000 RPM and drill out the core to the
desired depth using an intermittent pulsing technique. Start the
bur – press it down – stop – pull the bur back etc..., in this way
the LA Axxess Bur melts and removes the plastic core. You could
start this procedure by making a center mark with a small round
bur. The LA Axxess Burs should only be used in the top coronal
part of the filling until just below the canal opening. When using
the LA Axxess Bur, the obturator core and gutta percha will, due to
the friction heat, melt and be coiled out of the canal. However, the
plastic core will only melt to the point where the LA Axxess Bur is
placed.
3. When the desired depth has been reached using the LA Axxess
Bur, use your usual post space bur. Choose a bur dimension that
fits the post system and complete the post preparation. Other
cutting burs may be used, but care should be taken to prevent
perforation or displacement of the apical portion of the obturator
core.
3. Retreatment of an obturated root canal
Removal of the obturator is relatively simple prior to the gutta percha cooling.
Simply grasp the excess core with cotton pliers and remove it. Once the
gutta percha has cooled, or for retreatment at a later appointment, removal is
easiest achieved by using a Peeso bur, Gates, Rotary file or similar.
1. Place the selected rotary instrument between the canal wall and the
plastic core so that the rotational direction will be counter clockwise. Use
the instrument at very low speeds (250-400 rpm) and work slowly until you
feel resistance. The instrument will grasp between the plastic core and the
canal wall. The plastic core will be coiled out of the canal after a short time.
2. If necessary, a small dimension hand file can be worked down apically
along the plastic core.
3. When the plastic core has been pulled out of the canal, the gutta percha
is removed by traditional means.
Technique tips
1. Obturating multi-rooted cases
There will almost always be more than enough gutta
percha on each obturator. When obturating the canal, the
gutta percha and sealer will therefore be transported to
the coronal part of the tooth and in this way block the
opening creating a challenge when working with multiple
canals. Here is a step by step guide for obturating mul-
tiple canals.
1. Obturate the shortest canal first.
2. Place paper points or size verifiers in the other
canals prior to obturation to prevent them being cov-
ered by gutta percha. Remove them as each canal is
obturated.
3. While there is sufficient gutta percha on each obtu-
rator to fill even the most severe internally resorbed
canal, it may be too much in some cases. If it is obvi-
ous that there will be an excess of gutta percha for the
canal, use a sharp blade to trim some of the material
from the coronal end of the central core prior to heat-
ing. Care must be taken not to remove too much gutta
percha or fracture the obturator.
2. Post space preparation
Post space creation is accomplished by removing the
coronal portion of the obturation. Since the coronal 6 mm
of the plastic core is hollow, this procedure should be
easier with the Soft-Core Endodontic
Obturator than with other obturation systems.
STEP 2: Heating of the obturator
Place the selected obturator in the Soft-Core heater and activate the heater.
For more information on how to use the heater, please see section 1 of this
manual.
STEP 3: Application of sealer
While the obturator is heating, mix any heat resistant sealer with long
working time (a non-eugenol sealer is recommended). Make sure that
the root canal is completely dry, before applying sealer. Place a very thin
coating
of sealer on the wall of the canal. Too much sealer is neither desirable nor
necessary. Utilize a paper point or a Soft-Core Size Verifier
to apply a thin layer of sealer on the canal walls. When
obturating more than one canal, apply sealer in all
canals at once.
STEP 4: Insertion of the
obturator into the canal
When the oven indicates that the obturator
is ready for use, the obturator may be removed
from the heater.
Immediately insert the obturator into the
canal to the working distance, without
twisting the handle, and while using a firm
and steady pressure.
Important: The obturator should be inserted
to the full working length.
STEP 5: Removal of the handle,
excess central core and gutta percha
The handle, excess core and gutta percha may be
removed once the gutta percha has hardened.
1. For canals less than 18mm: Twist the
handle and plastic core to one side to break
off the excess.
2. For all Canals: Stabilize the plastic core
with a finger or cotton pliers, and cut away
the handle and excess plastic core with a
small inverted cone bur.
Important: Be careful to prevent vertical
movement of the core to minimize the
chance of disturbing the apical seal.
Trim away the extra gutta percha using
an endo excavator or similar instrument.

A step-by-step guide to the
Soft-Core Endodontic
Obturator
Before using the Soft-Core Endodontic Obturator,
assure that you have achieved the following:
A. A properly cleaned and shaped canal – the key to
any successful root canal filling. Utilize any technique
which provides a smooth tapered form, and provides
you with a coronal opening wide enough to give
room for the instruments.
B. A completely dry root canal.
C. An established working length. The plastic core is
flexible enough to negotiate curved canals. It is highly
advised that rotary files with a higher conicity are
utilized to create a sufficient taper for the obturator
core. When using files with a conicity of .02, it is
advised to combine them with a procedure using
Gates Glidden Drills or other les which can be used
to create a sufficient opening in the coronal part of
the canal.
The use of size verifiers is always recommended.
STEP 1: Determine the working length and choose
the proper obturator size
The working length is measured all the way to the apex. We
recommend measuring the working length from the edge of the
cusp. The working length can advantageously be measured by use
of both x-ray, file and electronic apex locator. Soft-Core Size Verifiers
are radiopaque and can be used for working length verification.
Generally, the appropriate size Soft-Core Endodontic Obturator will
be the same size as the last file used at the apex of the canal.
Tip: For very narrow and/or highly calcified canals, it may be
useful to select one size smaller than the last file used at apex.
If you do not use rotary files with a taper of 4 % or more, you
should always verify the size of the cleaned root canal with a
size verifier before inserting the obturator.
Setting the working length on your Soft-Core obturator
When the size verifier has a slightly loose fit in the apical
third, the rubber stop is placed at the working length.
Afterwards, the working length is transferred to the
obturator. Soft-Core obturators and Size Verifiers
are the exact same length.

Operating the Heater
1. Pre-heat the heater.
2. Place 1 to 4 obturators in the slots in the
obturator rest.
TIP: Place the first obturator to be used in
slot #1, the second in slot #2 etc.
3. Press the timer activation button to
plasticize all of the obturators. The timer
will chime and the timer status light will
turn red to indicate that the time cycle has begun. It is not necessary to
re-activate the timer or re-plasticize the obturators once they have
been heated, unless a new obturator is added. The heater will keep
them at the appropriate temperature for up to 30 minutes.
4. Once the oven sounds a long chime and the timer status light is green,
the obturator(s) is ready for use. To prevent using an unheated obturator,
Soft-Core recommends using the heated ones prior to adding additional
obturators to the heater. If it is necessary to add another obturator,
re-activate the timer and do not use until the timer chimes,
RE-ACTIVATING THE TIMER WILL NOT HARM THE OBTURATORS.
5. Once all the needed obturators have been used, remove and dispose
of the unused obturators.
6. If the heater is going to be used again on the same day, it should remain
on between procedures.
Service and Repair
The Soft-Core heater is covered by a 1-year warranty.
CAUTION: The Soft-Core heater must only be serviced and repaired by
your Soft-Core distributor, otherwise the warranty will be void.
Cleaning
Cleaning the unit after each procedure is recommended.
1. Unplug the heater and remove the obturator rest by
rotating it counter-clockwise. The obturator rest can then
be cleaned using a damp cloth with a disinfectant. This
should be done after each procedure.
2. Use a damp cloth to wipe down the outside of the heater
with a disinfectant. Do not spray or wipe down the inside
of the heater.
3. Once the heater and obturator have cooled, any gutta
percha on the heating chamber, ceramic elements or on
the rest can be removed with a dull instrument.

The Soft-Core Endodontic Obturator
A Soft-Core Endodontic Obturator is a core of biocompatible plastic, sized
according to ISO standards sizes 20 to 60, coated with thermoplastic gutta
percha. The obturator sizes correspond to the ISO standards of root canal
files. A single obturator is all that is needed to totally obturate a root canal.
The result will always be a perfectly placed root canal filling with a tight
apical seal.

colour coded handle
24 mm 9 mm
A Soft-Core Endodontic Obturator consists of three parts:
1. Plastic handle with a metal insertion pin
The injection molded plastic handle is color-coded ac-
cording to the size of the obturator. The stainless steel
insertion pin is 9 mm long, and is permanently attached to
the plastic handle. The hollow portion of the plastic core
surrounds 6 mm of the pin.
2. Outer layer of thermoplastic Natural GP™ gutta
percha
The gutta percha is reversible thermoplastic. This means
that it becomes soft and highly adhesive when heated to
temperatures above approx. 100°C. When cooled it re-
turns to a firm rigid state. Another heating will once again
make the gutta percha soft and adhesive.
3. Plastic core with endo stop
The tapered plastic core is sufficiently flexible to negotiate
curved canals.
The Soft-Core plastic core is slightly oval-shaped. This
secures adequate backflow of the heated gutta percha.
The length of the core is 24 mm. The coronal 6 mm of the
core is hollow to accommodate the metal insertion pin.
A rubber endo stop is provided to indicate the working
distance measurement. The plastic core and gutta percha
are radiopaque.
