2. • Vacuum formers in the dental industry are used to
imprint opposing bite and fabricate other dental
appliances like sports mouth guards, bleach trays
and orthodontic appliances.
• These formers can use a variety of thermoplastics
depending on necessary thickness and flexibility
needed.
• A vacuum former should be composed of a
vacuum pump and a heating element
Also known as thermoforming

8. Procedure
Step 1
• Insert selected sheet
resin material into the
clamping frame. The S
or screw-handle clamps
allow adjustment of the
frame according to the
thickness of the
material used.

9. Step 2
• Place model or cast on
vacuum plate.

10. Step 3
• Slide clamping frame
upward until it locks
into position. Turn
main switch on.

11. • Allow appropriate time
(usually 2-4 minutes)
for the material to
heat sufficiently to
achieve optimal sag for
vacuum forming.
Wait 2-4 minutes!

12. • Most other
materials are
heated until they
sag 0.5-1 inch

13. • Milky, semi-
transparent coping
material should be
formed when it
becomes clear and
barely begins to sag.

14. Step 4
• When the desired sag
has been achieved,
lower the clamping
frame over the model.
Activate the vacuum. A
smooth, controlled
lowering is
recommended forthin
materials.

15. Step 5
• Run vacuum motor
for 10-20 seconds
for thin plastics and
20-40 seconds for
thick materials to
ensure adaptation.
Turn off main switch.
Allow material to
cool until it is
comfortable enough
to handle.

16. Step 6
• Trimming of the
appliance.

17. • The Machine III has been a staple in
Keystone Industries’ long-lasting line of
highly recommended vacuum former
machines.
• more power than any other dental
vacuum former, which means the
production of more accurate and
definite dental thermoplastic appliance.
• This machine is used to process
bleaching trays, sports mouthguards,
implant stints, temporary splints, custom
impression trays, denture bases, copings,
temporary crowns and bridges and
orthodontic appliances.Machine III

18. • the Machine IV’s compact and
lightweight design takes less space
than other vacuum formers and is
can be easily picked up and stowed
away when not in use.
• The vented heated cover allows heat
to quickly dissipate, allowing the
machine to cool quicker.
• A locking handle allows varying the
height of the material play during the
heating process.
• Built-in safety timer that shuts down
the heater if not used for 15 minutes.
• The base of the machine is made
from super strong, lightweight space-
age thermoplastic material that is
designed for high-temperature
application.
Machine IV

19. • The Single Chambered
Vacuum Former is an
economical answer that can
still excellently fabricate most
thermoplastic appliances.
• The all-aluminum construction
eliminates rusting and the
heating element is
symmetrically engineered for
uniform heat distribution.
• The hexagonal post keeps the
frame from rotating or sliding.

Sta-Vac II Vacuum
Forming System

22. • This new attachment works in
conjunction with keystone industries
vacuum formers to create a better
fitting dental appliance.
• The dome uses positive pressure during
vacuuming, allowing for a form-fitting
mold of thermoplastics.
• The pressure dome hooks into any
existing air compressor lines to provide
extra pressure when adapting
thermoplastics over an existing model.
• Works great for making laminated
mouthguards, heavy-duty splints,
hard/soft dual laminated splints,
proflex base plates, model
duplication, orthodontic retainers and
more.
KEYSTONE - Pressure
Dome

23. • The powerful pressure unit provides
superior adaptation for dental plastics
using laboratory or operatory internal air
compressors.
• Because the unit has no motor, it is
compact and very quiet. Also, the
vacuum pressure from an office
compressor is usually greater than the
pressure generated from smaller
vacuum units.
• The greater the pressure, the better
definition and adherence the dental
appliances will have.
