Gergen’s · 3D printed night guards
G-Force Night Guard
The night guard designed on the scan and printed in Keystone KeySplint. Every point the thickness you prescribed, the bite set before it is made, and a replacement that is the same guard again. Hard for the grinder, soft for the patient who will not wear hard.
The thickness you asked for, everywhere
A pressure-formed guard thins over the cusps. A printed one is the thickness you specified at every point, because the thickness is in the design.
Occlusion set before it exists
The scheme is built against the opposing scan, flat plane or with guidance, and printed that way. Less grinding-in at the chair.
Identical on remake
Lost, worn or chewed through: the file is kept, and the replacement is the same guard. No new impression, no drift.
Resins made for this
KeySplint Hard and Soft are night guard resins, not general printing resins. Both are FDA 510(k) cleared for splints and night guards.
Two guards
Hard for the grinder. Soft for the patient who won’t wear hard.

Which one
Pick by the patient, not the material.
Most practices settle on one and prescribe it for everyone. The patients who come back with a guard in a drawer are usually the ones who got the wrong hardness.
- Heavy grinder, broken guards before
- Hard
- First guard, or gags on bulk
- Soft
- Protecting new restorations
- Hard
- Daytime clencher who needs to talk
- Soft, thin
- Not sure
- Say so on the Rx and we will recommend
Same printer, other designs
Splints we also print
