By incorporating your occlusion (the way your upper and lower teeth fit together) into your custom guard, we can get added stabilization of the head by head and neck muscles. Due to the thickness and elasticity of the material, athletes can safely clench down on them during competition.
This clenching activates various head and neck muscles which stabilized the head. Concussion specialist Dr.Karen Johnston states that, “the force require to concuss a fixed head is almost twice that of a mobile head.”
Further studies show that intracranial pressure is more than halved when an athletes clenches down on a mouth guard during traumatic events.
