SISU^® is made from a non-compressible, perforated material and doesn't cave in under impact like conventional mouth guards. Using our one-of-a-kind Diffusix™ technology, the impact force is distributed over larger areas, which means less risk of dental injury during competition.

“the perforations in the SISU mouthguard act similar to the trusses on a bridge, allowing the structure to flex when an impact occurs.””
Johannes Schwank, Ph.D

Material Impact Dispersion

DIFFUSIX™ absorbs and diffuses impact throughout the entire mouth guard.

Conventional mouth guards are made from a material that's too soft to fully protect your teeth from harm.

SISU mouthguards are made from a material that absorbs and diffuses impact throughout the entire mouth guard, meaning that much less impact force is transferred your teeth.

Diffusix™ technology works with unique impact-absorbing perforations and special 'crumple zones' which direct the impact forces away from your teeth. When a SISU mouthguard is properly fitted, these energy-absorbing zones direct forces away from your teeth, reducing the risk of dental injury.

Energy Absorbing Crumple Zones

Just like a bridge is built in compartments that can move slightly, the perforations in SISU mouth guards oscillate under impact and absorb impact forces. Energy is directed away from the teeth, and into the specially designed crumple zones.

But why the perforations?

The perforations serve three important functions:

Custom fit
Vacuum-like suction allows you to create that custom fit so unique to your mouth, the guard stays snugly on your teeth during the entire game or practice.
Talk. Breathe. Drink.
Natural flow of air and saliva empowers you to talk naturally, breathe normally and stay hydrated during the game or practice.
Better Protection
Like the support systems on a suspension bridge, the perforations oscillate on impact and redirect the forces to scientifically engineered reinforced parts of the guard.
