A mouthguard is the most effective device for preventing dental or soft oral tissue trauma. Playing certain sports, especially the ones in which the player is in direct contact with the opposing player, a ball or a bat, enhances the risk of teeth loss, teeth or jaw fracture, lip and gum injury, etc. The frequency of sports-related orofacial injuries is 24,7%, while wearing a mouthguard reduces it to 4,3%. There are ready-made mouthguards available in sporting goods stores. However, an individual splint, produced in a dental practice or a dental laboratory, is designed to fit the player’s teeth perfectly. This is highly important because it ensures even distribution of impact force to the teeth.

Mouthguards are designed according to individual dental impressions. They are layered and some of their parts are reinforced. This guarantees their user complete dental safety. Due to the insertion of a thermoplastic material between layers, the initially concentrated force gets distributed in all directions, which significantly reduces the force vector, as well the force’s effect. This is extremely important for the prevention of sports-related orofacial injuries. Observed from the perspective of functional analysis, wearing a mouthguard ensures the force’s even distribution to all masticatory elements, as well as temporomandibular joints.
