Mouthguard occlusion using Occluform 3

By Peter Herring, Adv Dip Dent Tech, ACCDP

Awell-designed occlusal surface, particularly in a mouthguard designed for higher impacts, is vital to unlock the full protective capability of the appliance. While both the occlusal designs described here can be achieved by articulating and reheating after forming, we fortunately have the Occluform 3 for quickly creating high quality occlusal schemes in mouthguards. The advantages of incorporating the Occluform 3 into the mouthguard thermoforming process are multiple. The time alone saved by removing the need to re- articulate is substantial but this technique also yields technical improvements by negating the need to heat the material a second time, thereby risking distortion of the formed mouthguard.

Adding the occlusion this way is performed while the material is in a hot plastic state immediately after the material has formed, with the exception of the Playsafe Triple foils - these are imprinted 60 seconds after forming, when the foil has slightly cooled. The foils are then allowed to complete the cooling cycle with the opposing model in place before final finishing.

Figure 9 (left). With the occlusal opening set, after the final layer is formed, bring the Bite Spacer down into the hot foil (allow 60 seconds delay for Playsafe Triple foils). This will create a plane with point contacts as well as displace the material buccally and incisally for added protection (“Buccal Shield”).

Figure 10. Leave in place until the cooling cycle has completed, then release the Bite Spacer from the Face Chuck arms, raise the opposing model and gently remove the reusable Bite Spacer - the occlusion is completed.

Scantist 3D vanishing scan spray

The MPF Composite Warming Palette is designed to bring composite to a more malleable consistency which aids manipulation when restoring small or long span restorations, especially when extensive gingival adaption in hybrid cases is required. The Makrolon polycarbonate palette case has stable UV properties that prevents direct UV light from polymerising the composite within the tray. The LCD display shows the temperature of the actual glass plate which can be adjusted up or down.

Scantist 3D is an extraoral scan spray to optimise the recording quality for CAD/CAM scans, camera/video recordings, structured light scans, blue light scans, etc. It evaporates / sublimates automati cally after application. It contains no pigments and no titanium dioxide (TiO2) and causes no contamination of the object, environment or user. It creates a non-slip surface and the ultra thin layer thickness results in a very fine homogeneous coating. Efficient and economical thanks to application using a special valve and fine nozzle. It adheres to all mate rials - even on very smooth surfaces and has no corrosive effect.
