Sports have been reported as one of the major causes of maxillofacial region injuries. We reported that in contact sports especially, many players have tooth and facial bone damage. These injuries should be prevented by the efforts of the players and medical field workers.<BR>We are planning to develop proper protectors for mouth injuries, i.e. mouthguards. The most important point is that the mouthguard must play the physiological role consistent with facial bone dynamics.<BR>In this report, we showed the methods to evaluate the mouthguards made in various materials and shapes. This system was conducted to determine the effccts of mouth protectors on pressure changes and bone deformation within the facial bones reacted to a known impact delivered to the inferior border of the chin.<BR>The results show that there are sonic specific points in relation to the impacts on the facial bones with and without a mouthguard. The retromandibular regions, linguar side of the mental region and infraorbital regions are static points, but on the other hand, the inside and outside of the zygomatic arch region and nasal floor are active in the transmission of the force. According to these results, various materials were evaluated for their patterns of force transmissions, and it was possible to select a single material suitable for a mouthguard.
