I support the dual arch technology you have developed for the purpose of jaw impact reduction. Certainly cushioning the condyle and teeth with a 3-4 mm interocclusal elastomeric material helps reduce impact upward against the glenoid fossa and skull. The temporal bone is thinnest at the top of the glenoid fossa/housing of the TMJ, with as little as 1/8″ to 1/16″ thickness, and susceptible to injury, including perforation. The helmeted sports accelerate a whiplash fulcrum effect on the temporomandibular joint through chinstrap force. Cushioning the mandible down and forward is essential in mouthguard design related to impact energy mittigation. This also occurs with martial arts impact sports where a direct blow to the jaw can occur.
The design of airway opening for breathing, and protection of all the teeth are other advantages of your design.

The helmet-to-helmet shot knocked Tony Dorsett out cold in the second quarter of a 1984 Cowboys-Eagles game, the hardest hit he ever took during his Hall of Fame NFL career.
“It was like a freight train hitting a Volkswagen”, Dorsett says now.
“Did they know it was a concussion?” he asks rhetorically during an interview with The Associated Press. “They thought I was half-dead.”
