The diagnosed soft tissue or brain injury component of concussions is generally defined by the symptoms of the temporal lobe manifestations. However, there is an undiagnosed structural fractured component of concussions occurring within the jaw joint complex which is the focus of this invention. A precise imaging technique and the powerful 3D Cone beam scanning technology, together, have revealed fractures in temporal bones of the jaw joint space which supports the temporal lobe of the brain. These fractures are the results of the lower jaw impact forces that cause concussions and this mechanism account for a large percent of the concussions arising in sports and military operations. These fractures have never been considered, diagnosed, or treated in the management of concussions. Fracturing temporal bones in the jaw joint that supports the temporal lobe will certainly produce the symptoms of temporal lobe manifestations. With early detection, these fractures can be more rapidly healed, eliminating many temporal lobe symptoms of concussions. The device of the present invention reduces the risk of the lower jaw impact concussion and temporal bone fractures, while enhancing the ability to speak and orally communicate.
