2. Wax clasp using 12 gauge sprue wax. Wax connection to
framework incorporating two or three squares of meshwork.
3. Trim excess wax away. Clasps should be as close to 2mm x
2mm as possible. This size is important to ensure complete
injection of the DurAcetal.
4. Using a black felt-tip marker, place dashes on the facial and
tongue or roof area of the model. When aligned, these dashes
correspond to the tip of each clasp.
5. Mix one scoop of CDM brand Extra Hard Putty A with one scoop
of putty B. Mix the putty until consistent. Place the putty on the
occlusal surface and work down over the buccal and lingual
covering the clasp. When the putty is in place, observe the lines
created in step 4 to estimate where the tip of the clasp is. Using
the Elite Putty Tool, indent down to the base of the tool. Repeat
this step when creating two clasps making sure the rst putty
matrix is set as not to move or warp it.
7
myerson HOTSHOTELITE MANUAL ENGLISH.indd 7 3/23/10 9:54:29 AM

7. With the putty matrix removed, boil off the wax from the
model and partial.
8. After all the wax has been removed, put the putty matrix
and the model into a heating oven set at 235°F (113°C)
for 8 minutes.
Make sure to use the recommended amount of putty
The putty has two purposes:
To act as a matrix to form the clasp and insulate the area and hold
in heat If the putty matrix is too small, the matrix can ex and move,
and may not keep the injection area at the proper temperature.
Using enough putty is essential to ensure complete injections.
6. Remove the putty and drill a sprue hole from outside to inside
using a #8 2mm bur. Drill your sprue hole in through the indention
of the putty tool and out through the other side trying to come
as close as possible to the tip of the clasp. If you come out
ahead of the clasp tip, just make a channel from the hole to
the tip of the clasp. Make sure the channel is 2mm by 2mm.
Where the clasp joins the frame work, drill a hole out through
the putty coming out the lingual side. This is a vent hole and
is very important to ensure a proper injection.

Do not place the model/ appliance in a heater set at a temperature
any higher than 235°F (113°C), some dental materials (acrylic) will
begin to degrade at temperatures higher than 235°F (113°C).
9. With the Injection Sleeve removed from the device, turn on
the myerson HotShotElite. To set the Melt Temperature,
press the Scroll Key once until “SP1” reads on the display.
Use the up or down keys to adjust the Melt Temperature
to 392°F (200°C). Pressing both the up and down keys
simultaneously will return the display to the process
temperature. See Section 4 for more information about
setting the Melt Temperature.
10. Allow the device reach the set temperature before
proceeding.
11. If using DurAcetal from a 225g bottle, measure out 8 grams
of DurAcetal (10ml mark on the measuring cup). If using
a Single Shot, pour the entire contents of the Single Shot
into the Injection Sleeve. Using the ller funnel, pour the
DurAcetal into the Injection Sleeve.
INJECTION SLEEVE MUST BE AT ROOM TEMPERATURE
BEFORE FILLING.
12. To load the device, slide the lled injection sleeve into the
end of the device. Then rotate the sleeve clockwise until the
sleeve locks into place. Place the loaded gun on the supplied
base as shown. Set a timer for 8 minutes and allow the injector
to heat undisturbed.

myerson HOTSHOTELITE MANUAL ENGLISH.indd 9 3/23/10 9:54:34 AM

13. When the timer sounds, place the Injection Rod into the back
of the injector with the teeth facing down. Push the rod into the
injector until it contacts the molten material. Squeeze the trigger
and discharge the aerated molten material onto the supplied
injector base until the ring on the injection rod reaches the back
of the injector. For safety reasons, expel molten material on to
Elite injector stand only. The material will not stick and is easily
removed once cooled. Allow the material to fully cool before
removing and wear supplied safety gloves.
DO NOT ATTEMPT TO REUSE INJECTED MATERIAL.
This process is important to keep aerated material from
becoming part of the final clasp or appliance.
14. After priming the myerson HotShotElite for injection, use the
supplied gloves to clear off the tip of the injector with your nger.
If material bulges from tip after cleaning, pull back on the
injection rod about 3mm. This will take the pressure off the
material and keep it from bulging out the tip. A bulge from
the injector tip can cool quickly and possibly plug the sprue
during injection. Pay attention not to allow a plug to form.
This may cause an incomplete injection.
10
myerson HOTSHOTELITE MANUAL ENGLISH.indd 10 3/23/10 9:54:36 AM

15. Take the model and putty out of the oven, place the tip of the
injector into the putty indent and squeeze the trigger once and
hold the trigger in the pulled position keeping pressure on the
injection for 5 seconds. Do not repeatedly pull the trigger.
IF CREATING A SECOND CLASP ON THE SAME PARTIAL,
REMOVE THE INJECTOR FROM THE PUTTY, CLEAN THE
TIP, AND ALLOW THE INJECTOR TO SIT FOR ONE MINUTE.
THEN INJECT THE SECOND CLASP FOLLOWING THIS
SAME PROCEDURE.
16. Expel the remaining material onto the Elite gun stand and
remove the rod. While wearing heat resistant gloves, remove
sleeve and nozzle from gun and place on metal stand to cool.
Refer to Section 5 for more information regarding cleaning
of the sleeve and nozzle. Let the model bench set for about
10 minutes or until the model is cool to the touch.
17. Section the putty matrix using a thin bladed knife. Cut a
section of the putty with the knife and using an instrument,
pry off the pieces of the putty until all the putty is removed.

section 10 ~ adding a myerson
DurAcetal Clasp to an existing
removable partial denture
The following procedure outlines the steps necessary to create
DurAcetal clasps onto an existing removable partial denture.
1. Using CDM brand Thermoplastic Model Separator paint the
area on the model where the clasp will touch. Be sure to wear
eye protection and use proper air ventilation. Avoid skin contact.
After the separator dries, place the partial on the model.
2. Mark where the clasp will connect to the partial. Using a #8
round bur (2mm) drill into the partial and exit the partial on
the lingual side. A counter angle will help the clasp lock into
the partial.
3. Wax the clasp and create the putty matrix as previously
described in section 9.

Section 13 ~ myerson VisiClear
or myerson DuraFlex flexible clasps
to metal framework
Myerson VisiClear and myerson DuraFlex have been specially designed
for creating strong yet exible clasps using the myerson HotShotElite
handheld clasp injector. The following is the procedure for creating
VisiClear clear clasps or DuraFlex tissue-coloured clasps onto a
metal framework.
1. Using CDM brand Thermoplastic Model Separator paint the
area on the model where the clasp will touch. Be sure to wear
eye protection and use proper air ventilation. Avoid skin contact.
After the separator dries, place the partial on the model.
2. Create the clasp using 12 gauge sprue wax. Place the wax
down at the gingival. Using a hot spatula, seal the sprue wax
to the model and extend the wax down onto the tissue.
This will give the clasp stability. Once you are done waxing,
make surethe clasps are 2mm by 2mm. Wax connection to
framework incorporating two or three squares of meshwork.
3. Mark the model where the tips of the clasps are located using
a marker. Mark a line on the front of the model and on the
palate or tongue side. These lines will help once the putty is
on the model, later you will have an idea where the tips of the
clasps are. 15
myerson HOTSHOTELITE MANUAL ENGLISH.indd 15 3/23/10 9:54:50 AM

4. Mix one scoop of CDM brand Extra Hard Putty A with one scoop
of putty B. Mix the putty until consistent. Place the putty on the
occlusal surface and work down over the buccal and lingual
covering the clasp. When the putty is in place, observe the lines
created in step 3 to estimate where the tip of the clasp is. Using
the Elite Putty Tool, indent down to the base of the tool. Repeat
this step when creating two clasps making sure the rst putty
matrix is set as not to move or warp it.
5. Remove the putty and drill a sprue hole from outside to inside
using a #8 2mm bur. Drill your sprue hole in through the
indention of the putty tool and out through the other side trying
to come as close as possible to the tip of the clasp. If you come
out ahead of the clasp tip, make a channel from the hole to the
tip of the clasp. Make sure the channel is 2mm by 2mm. Where
the clasp joins the framework, drill a hole out through the putty
coming out the lingual side. This is a vent hole and is very
important to ensure a proper injection.
16
myerson HOTSHOTELITE MANUAL ENGLISH.indd 16 3/23/10 9:54:52 AM

6. With the putty matrix removed, boil off the wax from the model
and partial.
7. After all the wax has been removed, put the putty matrix back
on the model and place the assembly into a heating oven set
at 235 °F (113°C) for four minutes.
8. With the Injection Sleeve removed from the device, turn on the
myerson HotShotElite. To set the Melt Temperature, press the
Scroll Key once until “SP1” reads on the display. Use the up or
down keys to adjust the Melt Temperature to 446°F (230°C).
Pressing both the up and down keys simultaneously will return
the display to the process temperature. See Section 4 for more
information about setting the Melt Temperature.
9. Allow the device to reach the set temperature before proceeding
.
10. Using the ller funnel, pour the entire Single Shot of myerson
VisiClear or myerson DuraFlex into the Injection Sleeve
(we recommend you use silver Injection Sleeve with VisiClear
and the blue Injection Sleeve with DuraFlex).
Do not use any Injection Sleeve for more than one type of
material; contamination may occur.
INJECTION SLEEVE MUST BE AT ROOM TEMPERATURE
BEFORE LOADING THE MATERIAL.

11. To load the device, slide the lled injection sleeve into the end
of the device. Then rotate the sleeve clockwise until the sleeve
locks into place. Place the loaded injector on the supplied base
as shown. Set a timer for 4 minutes and allow the injector to
heat undisturbed.
12. When the timer sounds, place the Injection Rod into the back
of the injector with the teeth facing down. Push the rod into the
injector until it contacts the molten material. Squeeze the trigger
and discharge the aerated molten material onto the supplied
injector base until the ring on the injection rod reaches the back
of the injector. For safety reasons, expel molten material on to
Elite injector stand only. The material will not stick and is easily
removed once cooled. Allow the material to fully cool before
removing and wear supplied safety gloves.
DO NOT ATTEMPT TO REUSE INJECTED MATERIAL
Note: This process is important to keep aerated material
from becoming part of the final clasp or appliance.
13. After priming the myerson HotShotElite for injection, use the
supplied gloves to clear off the tip of the injector with your nger.
If material bulges from tip after cleaning, pull back on the
injection rod about 3mm. This will take the pressure off the
material and keep it from bulging out the tip. A bulge from the
injector tip can cool quickly and possibly plug the sprue during
injection. Pay attention not to allow a plug to form. This may
cause an incomplete injection.
18

14. Take the model and putty out of the oven, place the tip of the
injector into the putty indent and squeeze the trigger once and
hold the trigger in the pulled position keeping pressure on the
injection for 5 seconds. Do not repeatedly pull the trigger.
IF CREATING A SECOND CLASP ON THE SAME PARTIAL,
REMOVE THE INJECTOR FROM THE PUTTY, CLEAN THE
TIP, AND ALLOW THE INJECTOR TO SIT FOR ONE MINUTE.
THEN INJECT THE SECOND CLASP FOLLOWING THIS
SAME PROCEDURE.
15. Expel the remaining material onto the Elite injector stand and
remove the injection rod. While wearing heat resistant gloves,
remove sleeve and nozzle from injector and place on metal
stand to cool.
Refer to Section 5 for more information regarding cleaning of
the sleeve and nozzle. Let the model bench set for about
10 minutes or until the model is cool to the touch.
16. Section the putty matrix using a thin bladed knife. Cut a section
of the putty with the knife and using an instrument, pry off the
pieces of the putty until all the putty is removed. Notice the
button of material on the lingual side. This if from the vent hole
created in step 5 of this section.

section 14 ~ finishing & polishing
Myerson offers several products that make it quick and easy to nish
and polish thermoplastic materials.
The Finishing Bur Kit includes all the necessary burs to trim and con-
tour a thermoplastic appliance.
•The diamond disc is used for removing the sprues and eliminating
ashing or other unwanted material.
•The #8 round bur is used when creating sprue holes as well as
any area where 2mm x 2mm is critical.
•The egg shaped burs work great for bulk reduction and ne tuning
of DurAcetal frameworks or DuraFlex partials.
•The reversed cone bur and diamond saucer bur can be used for
ne details the other burs can’t create.
The Polishing Kit was designed to decrease the time it takes get an
appliance ready for try in. Working from yellow to red to blue to green,
the appliance will become increasingly smooth. Finish off the appliance
with the rag wheel and a small amount of Fine Scratch Remover for that
high shine. (See our current catalog for details, Item No. FN-0200))
17. Finish and contour the clasp to the desired length and thickness
using the CDM Brand Finishing Bur Kit (not included in any
HotShoElite Kits)
18. See Section 14 for tips on nishing and polishing.
19. The nished appliance is now ready for try in.
