The safety benefits of mouthguards have been demonstrated in many studies, with many authors and sports dentists strongly recommending the wearing of mouthguards. However, wearing a mouthguard with incorrect occlusion might cause a variety of problems. It comes as no surprise that a traumatic blow to the chin, while wearing an insufficient mouthguard lacking anterior contact, can result in severe distortions to the mandibular bone, and bone fractures. The aim of this study was to clarify how ineffective insufficient occlusal supporting mouthguards are and how dangerous they can be to use. Consequently, in this study, occlusal supportive areas were varied and accelerations of head and distortions of the mandible were measured using an artificial skull model and a pendulum impact device. As a result, the distortions of the mandible tended to increase as the supported area decreased. On the contrary, accelerations of the head decreased as the occlusion part decreased. Thus, a lot of impact energy was consumed in the distortion of the mandible; accordingly, it seemed that only a little destructive energy was transferred to the head. From this study, it would seem that wearing a mouthguard, which is insufficient in the occlusion, has the potential of causing a bone fracture of the mandible. Consequently, mouthguards should have proper occlusion.

In contact sports such as rugby and American football, there are injuries to the head, neck, and oral regions when playing sports due to collision of the body and sports goods. Interest is growing in the prevention of trauma and injuries due to contact sports, according to the increasing use of mouth protectors. It is thought that the wearing of inappropriate mouth protectors can affect both athletic performance and bodily functions and can even lead to serious injuries. In this study, several types of upper jaw resin splint were used in various horizontal maxillomandibular positions to investigate their influence on the cervical neck muscles. The effects on cervical back strength and the activity of the neck and mastication muscles were observed. The results suggested that positional changes in the horizontal maxillomandibular affect cervical back strength and the activity of the neck and mastication muscles. Therefore, it seems important to select an appropriate mandibular position when wearing a mouth protector.
