Introduction

How to make a 4mm Erkoloc Pro bite splint with a flat plane using the ERKOFORM-3d and Occluform-3 attachment.

Figure #1

To begin, place the upper model into the model container and tighten the Allen screw.
Figure #2

All thermoforms areas will be above the model container.
Figure #3

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

Then place the model container into the ERKOFORM-3d thermoforming chamber and align the dots.
Figure #5

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

Then be sure the joint screw is tightened as shown.
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 an Erkoloc Pro disc from its packaging.
Figure #12

Enter the proper material into the machine.
Figure #13

Enter the thickness into the machine.
Figure #14

Remove the disc cover ring.
Figure #15

Place the Erkoloc Pro disc with the soft side down, toward 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

Then using the Isolac separator, paint the upper model completely and allow it to dry.
Figure #19

Also, paint the opposing model.
Figure #20

Now 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 over the thermoformed sheet 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 completely 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

Remove the model.
Figure #31

Now using the fissure bur, cut the splint away from the disc.
Figure #32

Using 10,000 RPM begin to 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 you've cut the disc, remove the splint as shown.
Figure #34

Now you're ready to begin your trimming.
Figure #35

Using the crosscut carbide, begin to fine-tune and smooth the edges of the Erkoloc Pro.
Figure #36

You will note how easy it is to trim away all flash and begin to contour the splint.
Figure #37

As shown, you can see that there has been some relief around the anterior region. Any type of modification to the edges of the splint can be made.
Figure #38

Now begin to feather the palette area, and continue smoothing the splint.
Figure #39

Now using the Lisko-S disc, go around all cut areas and begin to smooth the splint. The Lisko-S disc is ideal at 10,000 RPM.
Figure #40

Then using a polishing paste with a cotton wheel, begin to high shine the splint.
Figure #41

As you see, Erkoloc Pro will shine up to a very high shine and produce a sparkling clear transparency.
Figure #42

You've now completed an Erkoloc Pro hard/soft splint.
