Keystone Industries’ Pro-form Mouthguard delivers a high level of protection, retention, comfort, and fit without hindering speech, breathing, and most of all athletic performance. The custom-fit mouthguard goes above and beyond typical boil-and-bite mouthguards because of a double layer of laminated sheet vinyl and a lingual plate imbedded behind the incisors. The mouthguard maintains its form because of the heat and pressure laminating process. The tensile strength is excellent due to the two layers of laminate while the density is maintained during the pressure laminated process for controlled, uniformed shape. Overall, the risk of injuries is lessened by about 90% when wearing a custom-made mouthguard.
