Our history of customer loyalty is a strong testament to our product quality. But just because we have a great product, doesn’t mean we can’t make it better! [SISU NextGen](https://blog.sisuguard.com/whats-different-about-sisu-nextgen) is the latest evolution in mouthguard engineering by the makers of SISU Guard. Simply put, it is the most powerful mouthguard we’ve ever built. With its unmatched quality and functionality, the SISU NextGen mouthguard was designed with the athlete in mind, and its unique new features are hyper focused on additional protection and comfort. ## **The Science of SISU: ** In our labs, we have put each mouthguard through strenuous testing to see how it performs in relation to its competitors. SISU Guards are made from unique medical grade thermo-polymer, which is, remarkably enough, free of harmful chemicals. SISU material is non-compressible, which enables SISU Guards to outperform the competition in tensile strength tests.   The [tensile strength](https://simple.wikipedia.org/wiki/Tensile_strength) of our SISU material is consistently at least 30% higher than that of conventional EVA (a material most other mouthguards are made of). In reality, our material performs even better, due to the built-in Diffusix™ Technology, better protecting your teeth from damage. (Learn more about the [Science of SISU](http://www.sisuguard.com/the-science-of-sisu/)). ## **Engineering: ** Powered by our patented Diffusix™ Technology and engineered to withstand even more impact, the SISU NextGen mouthguard delivers even more protection with its scientifically re-designed perforation pattern. Based on suspension bridge technology, the main function of the perforations is to redirect the forces of impact. On impact, perforations oscillate and send the forces into our scientifically engineered Crumple Zones - the reinforced points of the guard that don’t cave in under pressure. Here, the force of impact is redirected away from teeth and absorbed into the non-compressible surface of the guard. This unique design empowers SISU NextGen to protect you from even the toughest hits. ## **Comfort:** Custom fit, remoldable SISU NextGen mouthguards feature a wider bite pad, rounded edges and improved moldability. Rounded, bevelled edges soften the point of contact between the guard and the mouth, and improvements in the perforation alignment enable maximum dissipation of force transmitted from the point of impact. Superior protection is not the only function of the perforations. They also allow for flexibility to create an intimate custom fit, so unique to the player’s mouth that the guard remains in the mouth during the entire game or practice. Additionally, perforations allow for natural flow of air and saliva to empower athletes to talk normally, breathe naturally and stay hydrated during the game. ## **Core Features: ** - 1.6 mm thin - Custom Comfort fit - Remoldable - Wider bite pad - Rounded Edges - Works with braces - Talk, Breathe, Drink - Diffusix™ Technology - Stays in the mouth the entire game or practice - Minimizes chewing
