There is no fixed amount. Thickness loss depends on model height, occlusal anatomy, material, original sheet thickness and how far the material has to stretch. Prominent cusps and incisal edges…

How do I make a thermoformed splint more comfortable?
Choose an appropriate material and thickness, avoid unnecessary bulk and excessive extension, and finish the margins smoothly. Retention should be firm without making insertion and removal difficult. A hard/soft material…
How do I avoid excessive retention on a splint?
Identify significant tooth undercuts before forming and selectively block out only the areas likely to lock the appliance onto the model or patient. Consider model orientation and the planned trim…
How do I block out undercuts before thermoforming?
Fill significant undercuts with a suitable heat-resistant block-out material before thermoforming. Common areas include deep interproximal spaces, strongly inclined teeth, pontic areas and pronounced cervical undercuts. The goal is selective…
Can a thermoformed splint be repaired?
Some thermoformed splints can be modified or repaired using compatible materials, depending on the original polymer and the type of damage. Minor adjustments or additions may be possible, but a…
How long should a thermoformed occlusal splint last?
There is no fixed lifespan. Durability depends on the material, thickness, appliance design, severity of bruxism, cleaning method, frequency of use and whether the patient chews or grinds heavily on…
What is the difference between a thermoformed and 3D-printed splint?
A thermoformed splint is made by heating a thermoplastic sheet and adapting it over a physical model. A directly 3D-printed splint is manufactured from a digital design using a printable…
Why is my thermoformed splint too loose?
Possible causes include excessive block-out, insufficient extension, inaccurate model reproduction, distortion during removal or use of material that is too flexible for the intended design. First check whether the appliance…
How do you adjust the occlusion on a thermoformed splint?
The occlusal surface can be adjusted after forming using appropriate rotary instruments and polishing techniques. Where compatible, additional material may also be added. An alternative is to incorporate the opposing…
Can occlusion be incorporated during thermoforming?
Yes. With an Erkoform machine and Occluform-3, the antagonist can be brought into the heated material during the forming process so an initial occlusal relationship is incorporated directly into the…
