Mouthguard testing. View of a mouthguard being subjected to an impact from a boxing glove. The mouthguard is fitted onto an artificial jaw designed to test the performance of various types of mouthguard. The jaw is the invention of Andrew Greasley of the Open University, England. It is made of a composite material and is fitted with teeth (white) moulded from a ceramic material. The mouthguard being tested is first fitted onto the jaw. Then the jaw is fitted onto a spring loaded support and subjected to an impact similar to that which could occur during sport. The performance of the mouthguard is evaluated by assessing the teeth for damage and dislocation.
