Thermoforming Machine Lab Technique - Erkoform-3d - Glidewell Direct Dental Thermoforming Lab Supplies

Introduction

This step-by-step technique explains how to make a bite splint with a flat plane using the Erkoform-3d with Occluform-3 attachment and 4 mm Erkoloc-pro co-polyester discs.

Figure #1
Begin by placing the upper model into the model container. Tighten the Allen screw.
Figure #2

As you see, all thermoformed areas are above the model container.
Figure #3

Fill the model container with steel granules. Be sure to fill in any open areas and pack firmly.
Figure #4

Next, place the model container into the Erkoform-3d thermoforming chamber and align the dots.
Figure #5

Loosen the joint screw on the Occluform-3 and place the opposing model. Tighten the Allen screw.
Figure #6

In this step, the joint screw is tightened.
Figure #7

With the model container in the thermoforming unit, position the open construction bite onto the upper model.
Figure #8

Then loosen the joint screw on the Occluform-3 hanger and position the opposing lower model into the bite.
Figure #9

Be sure the joint screw is tightened completely.
Figure #10

Remove the construction bite and close the Occluform-3.
Figure #11

Remove a 4 mm Erkoloc-pro disc from its packaging.
Figure #12

Enter the desired material into the machine.
Figure #13

Enter the thickness into the machine (shown in millimeters).
Figure #14

Remove the disc cover ring.
Figure #15

Place the Erkoloc-pro disc with the soft side down, towards the model. Then replace the disc cover ring.
Figure #16

Tighten the disc cover ring completely.
Figure #17

Place the Erkoloc-pro disc under the heater.
Figure #18

Use the Isolac separator to paint the upper model completely. Let it dry.
Figure #19

Repeat this step on the opposing model.
Figure #20

Use the granule cover template over the steel granules.
Figure #21

Prepare an Erkolen sheet to create the flat bite plane.
Figure #22

After heating is complete, remove the disc frame and thermoform.
Figure #23

Place an Erkolen sheet between it and close the Occluform-3.
Figure #24

Remove the Erkolen and imprint the opposing bite. Hold down firmly.
Figure #25

Be sure the incisal pin is completely seated on the Occluform frame.
Figure #26

Allow the disc to cool before removing.
Figure #27

Remove the disc foil ring and lift the disc frame.
Figure #28

Remove the model container from the unit.
Figure #29

Loosen the Allen screw and be sure the granules are over a container.
Figure #30

Now we will remove the model.
Figure #31

Cut the splint away from the disc using a fissure bur.
Figure #32

With the bur set to 10000 RPMs, cut the splint away from the disc completely. NOTE: Cutting the splint off the model will damage the model. We suggest a second model be made prior to starting the thermoforming procedure.
Figure #33

Once the disc is cut, remove the splint as shown.
Figure #34

Begin trimming your splint.
Figure #35

Using the crosscut carbide, fine-tune and smooth the edges of the Erkoloc-pro splint.
Figure #36

It is easy to trim away flash. Once trimmed, begin to contour the splint.
Figure #37

You can see that there has been some relief around the anterior region. At this point, you can make any type of modification to the edges of the splint.
Figure #38

Feather the palette area and continue smoothing the splint.
Figure #39

Using the Lisko-S disc, go around all cut areas and begin to smooth the splint. The Lisko-S disc is ideal at 10000 RPMs.
Figure #40

High shine the splint using polishing paste with a cotton wheel.
Figure #41

The Erkoloc-pro-fabricated bite splint shines up to a very high shine. It also provides sparkling clear transparency.
Figure #42

You've now completed your Erkoloc-pro splint.
