Our HXC and Damproband technologies add extra protection to the most vulnerable teeth.  These technologies are recommended for those who participate in combat sports.Technology Commonality:90% of oral injuries happen to the two front teeth. These technologies  help distribute energy forces from your two front teeth to stronger teeth that have bigger rootsDifferences Between the  Damproband and HXC Technologies:HXC technology is internal to the mouthguard. It is a hard layer inside two soft layers of the mouthguard. You can add artwork with HXC technologyDamproband technology is external.  We use high shock absorbing material called Damprotech. This material is used for the dispersion bands we constuct the mouthguard with.  You can NOT add artwork to our Damproband sinc the technology is external to the mouthguard not allow space for artwork or 3D designs.
