For a long time, the thermoformed splint was the usual approach: an impression with an impression tray, a plaster model, a heated plastic sheet drawn over the model and then finished by hand. Today this can be done digitally – and more precisely. We make occlusal splints and sports mouthguards by **3D printing**.

In short

For a printed occlusal splint, the teeth are scanned digitally, the splint is designed on the computer and printed layer by layer from a dental resin. Compared with a thermoformed splint, the fit is more precise and reproducible, the biting surface is matched directly to the bite, and if the splint is lost it can be remade from the stored data.

## Thermoformed or printed – the comparison

The printed splint is digitally matched to the bite.

## How the splint is made

Procedure 
1. **Functional diagnostics**We examine the muscles, jaw joints and bite and clarify which splint makes sense.
2. **Scan**The upper and lower jaw and the bite are recorded digitally in a few minutes.
3. **Design**Thickness, biting surface and guiding surfaces are planned on screen.
4. **3D printing**The splint is printed from a resin approved for use in the mouth and then finished.
5. **Fitting and check-up**We check the fit and bite and make adjustments in the first few weeks.

## Who is the printed splint suitable for?

- for night-time [teeth grinding](https://zahnarztpraxis-st-peter.de/en/guide/teeth-grinding-what-helps/) and clenching
- for [TMD](https://zahnarztpraxis-st-peter.de/en/guide/tmd-symptoms/) with jaw and muscle pain
- to protect ceramic crowns, veneers and implants in people who grind
- as a custom [sports mouthguard](https://zahnarztpraxis-st-peter.de/en/sports-dentistry-mouthguard-nuremberg/)
- with a strong gag reflex, because no impression tray is needed

Good to know

The splint protects the teeth and relieves the muscles, but on its own it does not remove the cause of grinding. If the splint, physiotherapy and relaxation are not enough, [botulinum toxin](https://zahnarztpraxis-st-peter.de/en/botox-teeth-grinding-nuremberg/) can be a complementary option.

## Frequently asked questions

Is a printed splint strong enough?

Yes. The splint is made from a dental resin intended for long-term use in the mouth, and its thickness is adapted to your situation.

What do I do if the splint is lost or breaks?

Because the design data remain stored, the splint can usually be reprinted without a new scan – provided your teeth have not changed.

Does health insurance pay for the printed splint?

German statutory health insurance contributes to a medically necessary occlusal splint. We discuss with you in advance whether any additional costs arise.
