Installation of the HEAT GUARD
To prevent damage, the myerson FlexPress™ has been shipped
with the heat guard not installed. To install the heat guard, place
the heat guard over the corner posts with the warning label UP.
Install the (4) black acorn nuts nger tight. The acorn nuts are
simply holding the heat guard down, so they do not need to be
wrenched tight.
The heat guard can be removed periodically for cleaning.
Just follow the above steps in reverse order to remove the
heat guard.
Thank you for your purchase. Feel free to call myerson with
any questions.

section 5 ~
Processing using the
“Run Stored Profile”
(Recommended Option)
1. From the main menu use the UP or Down buttons until the
“Run Stored Prole” is displayed then press the enter button.
2. Next use the UP/DOWN buttons until prole you wish to run
s displayed.
3. After selecting the prole the display will show the prole name.
Pressing ENTER will scroll between prole name, melt tempera-
ture, melt time and hold time. It is recommended to check the
setting before starting a prole.
4. Press the START button and the machine will begin running the
prole. If the machine is at room temperature, it will take approxi-
mately 15 minutes to reach the processing temperature.
5. Prepare the cartridge by scoring
a “+” using a utility knife.
See the illustration to the right. This will
create an even “Burst” of the cartridge
6. Next, coat the sides of the cartridge
with a light coat of release compound.
This will prevent the cartridge from sticking
to the walls of the heating chamber.
7. When the myerson Flexpress has calibrated itself at the Melt
Temp an alarm will sound and the upper display will read “LOAD”
signaling you to load the cartridge. At this time insert the cartridge
into the heating chamber, center the ask and tighten using the
ask strap and knobs. If you are not ready to start the prole at
this time and want to turn off the alarm, press the UP button.
This will silence the alarm, but the myerson Flexpress™ will
remain calibrated until you press START or put the unit in standby
by pressing the STBY button.
8. Press the START button to begin the prole. Now let the myerson
Flexpress™ do the rest. The unit will begin counting down the
Melt Time and once it expires the unit will automatically inject the
material into the ask. The piston will stay in the up position for
the duration of the Hold time then release.
9. The upper display will read “DONE”.
10. You can now remove the ask strap and knobs.
11. Grasp the ask using heat resistant gloves and press the
EXTEND/RETRACT button. This will extend the piston and
push out the remaining cartridge attached to the ask.

section 7 ~ myerson DuraFlex partial
injection procedure
The following procedure outlines the steps necessary to create
myerson DuraFlex Partials with the myerson Flexpress™ Digital
Injection System.
1. Evaluate the model for major undercuts and block out the
undercuts. Due to the exibility and adjustability of the material,
very little if any blocking out will be needed.
2. Paint the model with myerson Thermoplastic Model Separator
MS-0200.
7
section 6 ~
processing using the
“Re-run Last Profile”
1. From the main menu use the UP or DOWN buttons until the cursor
is to the left of “Rerun Last Prole” then press the enter button.
2. The display will show the prole name and prole settings of the
last injection. If this is not the prole you wish to run, press the
LEFT arrow button to return to the main menu.
3. The myerson Flexpress™ is now ready to process your case.
See steps 5-13 of Section 5 for a complete injection.
12. Press the EXTEND/RETRACT button again to retract the piston.
13. The myerson Flexpress™ is now ready to process another case.
Repeat steps 1-9 for your next injection.

3. Wax and set up the teeth just as you would for an acrylic partial.
4. Add the clasps to the partial. myerson,LLC recommends using
12 gauge sprue wax for creating clasps.
8

5. Coat the inside of the ask with a petroleum jelly. This will prevent
the stone from adhering to the ask.
6. Invest the partial using regular Buff stone. When stone sets, place
sprues using 3/16” (4.75mm) utility rope wax. Extend the sprue to
the injection port in the ask.
7. Coat the stone with stone separator and bolt the top half of the
ask in place. The utility wax should ll the injection port of the
ask. This will keep the stone from leaking out during the second
half of the investing process.
9

8. Pour up the ask using myerson, LLC’s Investing Stone
INVSTONE-25LB. This stone has been designed to prevent
the teeth from shifting during injection. Notice the stone is
not protruding from the widow in the ask.
9. When the last half of the stone is set, remove the bolts but leave
the ask together and place in boiling water.
10. Once the wax has been removed, remove and place holes in
the denture teeth. The holes in the teeth are very important.
They create the mechanical retention necessary to lock the teeth
in place as well as allow air to escape as the myerson DuraFlex
is injected. Once the holes have been created, the teeth need to
be placed back into the proper locations. A small dot of Super
Glue on the incisal area of the teeth will hold them in place as the
material is injected. Bolt the two halves together.
10

11. Next, turn on the myerson Flexpress™ by pressing the
ON/STBY button. Select the method of processing referred to
in sections 4-6.
12. When the myerson Flexpress™ has reached the preset
temperature, a buzzer will sound. At this time, insert the desired
myerson DuraFlex cartridge into the heating chamber with the
crimped end down. A light coat of release compound BS-0105
on the cartridge will help eliminate the cartridge getting stuck in
the heating chamber. Press the start button this will start the
injection cycle.
11

13. Place the ask onto the myerson Flexpress™, centering the sprue
hole of the ask over the center of the heating chamber. Lock the
ask in place using the ask strap and knobs.
14. When the timer expires, the myerson Flexpress™ will automatically
inject the myerson DuraFlex cartridge. The piston will stay in the up
position according to the hold time. Once the piston retracts, it is
safe to unscrew the hold down plate and remove the ask.
15. To remove the ask, loosen the hold down knobs and remove the
ask strap. Using heat resistant gloves, grasp the ask and press
the EXTEND/RETRACT button (lower right button). This will extend
the piston and push the crushed cartridge and ask out.
16. Press the EXTEND/RETRACT button again to retract the piston.
The myerson Flexpress™ is now ready for another injection.
17. After the appliance is divested, it can be placed in a stone remover
to eliminate any extra stone that is adhering to the appliance.
Notice how the Thermoplastic Model Separator MS-0200 has
created a smooth, clean surface on the underside of the appliance.
12

18. This is the nished myerson DuraFlex case. Ready for try in.

Section 8 ~ myerson DurAcetal
framework injection procedure
The following procedure outlines the steps necessary to create myerson
DurAcetal®frameworks with the myerson Flexpress™ Digital Injection
System.
1. Block out the saddles on the model. This is in preparation for the
acrylic that will be placed later. The thickness used is 1 to 1.5 mm
thick. You will notice the large tissue stop cut out of the wax.
Stability is the reason for the large tissue stop.
2. Below is the duplicated model. This model has been duplicated
using myerson Universal Stone UNISTONE-25LB.
The expansion stone accounts for the shrinkage that occurs
when myerson DurAcetal cools.
3. Place myerson’s Thermoplastic Model Separator MS-0200
on the duplicated model.
14

4. Wax up the framework.
5. Coat the inside of the ask with a petroleum jelly. This will
prevent the stone from adhering to the ask.
6. Invest the framework using regular Buff stone. When stone
sets, place sprues using 3/16” (4.75mm) utility wax.
Extend the sprue to the injection port in the ask.
15

7. Coat the stone with stone separator and bolt the top half of
the ask in place. The utility wax should ll the injection port
of the ask. This will keep the stone from leaking out during
the second half of the investing process.
8. Pour up the ask using myerson, LLC’s Investing Stone
INVSTONE-25LB. Notice the stone is not protruding from
the widow in the ask.
9. When the last half of the stone is set, remove the bolts but
leave the ask together and place in boiling water.
10. Once all the wax has been removed, bolt the two halves
together.
16

11. Next, turn on the myerson Flexpress™ by pressing the
ON/STBY button. Select the method of processing referred
to in sections 4-6.
12. After the appliance is divested, it can be placed in a stone
remover to eliminate any extra stone that is adhering to the
appliance. Notice how the Thermoplastic Model Separator
MS-0200 has created a smooth, clean surface on the
underside of the appliance.
17

13. Here you have your nished myerson DurAcetal appliance.
The holes in the saddle areas were created using a standard
round bur. This will allow the acrylic to mechanically retain to
the myerson DurAcetal framework.
