Thermoforming technique The instructions in this brochure are the suggestions of the Development Team of Erkodent. The fields of use as well as the fabrication procedures in Thermoforming Technique are not limited to the instructions that are shown and may vary. Please do not hesitate to contact us if you have any suggestions. Please find videos to the fabrication of several applications at: www.erkodent.com > Service/Download > Videos Basic principles of thermoforming: • The models should consist of hard plaster (class 3). For thermoforming the hard plaster can contain residual moisture but...

The function of the Occluform device Occluform-3 The Occluform is an occludator that can be integrated in a thermoforming unit to imprint the opposing bite (pat. 19915567). • The Occluform-3 can only be installed at the Erkoform units serie 3. • It allows to directly imprint the opposing bite in the Erkoform units serie 3 during the thermoforming process! • Plaster-free model fixation. • The single column construction enables best model accessibility. • The articulation of the models is ensured by a hydraulic system that can be fixed in every position. • The construction of the Occluform-3 device...

Occlusal splints with and without adjusted occlusion Materials & Accessories Fabrication: • Hard splints: • Hard / soft splints: (2-layered) • Semi-soft splints: • Tough-hard splints: Erkodur, adjusted splints 1.5 - 5.0 mm, stabilization splints 0.8 - 1.5 mm Erkoloc-pro, adjusted splints 2.0 - 5.0 mm, stabilization splints 1.0 mm / 1.3 mm Erkoflex-95, adjusted splints (biting) 2.5 and 4.0 mm Erkolign, 1.0 and 2.0 mm (at extreme stress, most resistant, but only limitedly adjustable) • For adjustment by addition: auto-polymerizing resin for Erkodur and Erkoloc-pro, Erkoflexsticks-95 (177 006) with...

7. Smooth the edges with Liskosil-l (10 000 rev/min). Smooth narrow interdental spaces with Liskosil-m or -s (10 000 rev/min). 8. If necessary, polish the matt areas with the polishing set using a lab handpiece, however, for these relatively thin splints a polish is mostly superfluous. Erkolign: smooth with Liskosil-m and -l and white silicone polishers. 9. It would be best to now take off the insulating foil. 10. Finished stabilization splint. Pay attention to the cleaning and maintenance instructions on page 34. Occlusal splint with adjustment by reduction (grinding), for ex. centric splint...

20. After cooling take it off the unit and finish as described in step 9 to 12. 21. Finished adjusted Michigan splint without addition, the splint consists in the occlusal area only of one material type. Pay attention to the cleaning and maintenance instructions on page 34. Soft occlusal splint with imprinted adjustment, for ex. relief splint Thermoforming material: Erkoflex-95, 2.5 and 4.0 mm, Shore A 95 22. Addition: Erkoflex-95, 2.5 mm Embed the models so far into the high grade steel granules that only the thermoforming area plus 5 mm protrude from the granules. Cover the granules with the...

36. Fix the antagonistic jaw onto the upper model plate. Prefix the model in a preferably high position with the arrest joint. Close the Occluform. 38. If a construction bite is available the models are articulated in the same way (3). 37. Point the supporting pin on the 0-line (arrow), open the arrest joint and articulate the models. The bite can be elevated to a median value. 39. Hold the upper model plate in position and firmly close the arrest joint. Open the Occluform. That way the imprint corresponds exactly to the bite registration. 40. Fill as many high grade steel granules in the pot...

Temporary appliances Materials & Accessories Fabrication: • Moulding as negative mould without bonding to acrylics for temporaries: • Moulding with bonding to acrylics for temporaries by a primer: • Primer for a durable combination of cartridge acrylics and liquid  powder acrylics with the foil types Erkodur. / • or model insulation and shrinkage compensation thermoform the ex works applied insulating foil together with the desired plate, in doing so the F insulating  shrinkage compensation foil has to show towards the model (otherwise primer, only insulation). / • over templates (110 900) to...

9. Press the mould onto the edentulous area. With suitable, mostly cartridge acrylics, the adaptation can also be done in the mouth. 10. To avoid a raised bite and to compensate for the thickness of the foil, put the temporary appliance into occlusion with the opposing bite. 11. Grind the edges with the crosscut tungsten carbide bur (> 20 000 rev/min). 12. Smooth and prepolish the edges with Liskosil-l (10 000 rev /min). 13. Smooth and prepolish narrow areas with Liskosil-m (10 000 rev /min). 14. Finished, break-stable temporary appliance out of a compound of foil (Erkodur or Erkodur-0M1/-A1/-A2/-A3)...

Radiation protection splints Materials & Accessories Fabrication: • Erkoflex, 4.0 and 5.0 mm, Erkoflex-95, 4.0 mm Model preparation: • When using plaster models: Erkogum (110 844) for blocking out, high-fusing wax (725 080) for filling bubbles in the plaster. Finishing: • Special scissors XL (220 301), tungsten carbide bur (110 837) for grinding, Liskosil-l (223 240) or Lisko-S (223 200) for prepolishing, hot air burner (177 540) and if necessary, FG-sheets (177 400) for shining Hints • Areas of the model (exterior vestibulum, oral floor) which obstruct the adaptation have to be removed.
