It is estimated that an athlete is sixty times more likely to sustain a dental injury while not wearing a mouthguard. This book indicates that there is a necessity for improving the impact absorption ability of mouthguards by considering how to achieve a full-balanced occlusion, improving design and developing materials.

The purpose of the study was to determine how use of a mouth guard and movement complexity affect reaction time of whole body movement. The design was developed to study whether wearing a mouth guard or not affects simple reaction time. Further the study examined the hypothesis that movement complexity affects simple reaction time. The experiment consisted of three prescribed whole body movements of varying complexity. Participants in the experiment were 12 college aged males enrolled in a kinesiology major. They were free from injury and had some experience playing sports. Reaction time was determined using ground reaction force data measured by a force plate. Video data captured by a single video camera were digitized to verify the onset of movement. A two-way analysis of variance with repeated measures on both factors revealed no significant mouth guard effect. A significant movement complexity effect resulted in longer reaction times for a high complexity movement than for low and moderate complexity movements that revealed similar reaction times. A significant interaction effect resulted in shorter reaction times on the low and moderate complexity movements when wearing a self-adapted mouth guard than when not wearing a mouth guard. The current study examined the "memory drum" hypothesis by applying new technologies for understanding whole body movement. Further research will be required to replicate the results of the current study and to apply them to practice.

Oral Physiology and Occlusion: An International Symposium contains the proceeding of the """"Bite Centennial"""" conceived as part of the 1976 Bicentennial Celebration of the College of Medicine and Dentistry of New Jersey. The symposium aims to provide a broad based review of the """"state of science"""" of oral physiology and occlusion. Organized into 13 chapters, this book first discusses the effects of lesions of jaw muscle spindle afferents on mastication and regulation of the incisal biting force in monkeys. Subsequent chapters describe the occlusal forces and mandibular movements; muscl ...

Advances in mouthguard design applied the dental technique of jaw-repositioning to not only prevent negative effects but to enhance athletic performance. Improved posture and proprioception have been observed with use of jaw-repositioning appliances (1-4). In a previous study, a jaw-repositioning mouthguard improved muscular power in athletes (5). We compared a neuromuscular dentistry-designed jaw-repositioning mouthguard to a standard mouthguard in a randomized, crossover study evaluating muscular endurance and anaerobic capacity in male athletes. The advanced jaw-repositioning mouthguard led to improved muscular power performance (6). Although effective, the neuromuscular dentistry-designed mouthguard was highly expensive causing it to be impractical for the typical athlete. The next two studies utilized affordable versions of the above mouthguard to expand the practical application of the findings. We evaluated the effects of two jaw-repositioning mouthguards on other aspects of physical performance including balance, flexibility, agility, power and strength in male athletes. A battery of exercise tests was completed in a randomized, controlled, crossover study. No significant differences between the jaw-repositioning mouthguards, the placebo mouthguard, and the no-mouthguard control were observed in these aspects of physical performance. Our final study evaluated the effects of two jaw-repositioning mouthguards on aerobic performance. Jaw-repositioning devices treat sleep apnea by increasing the size of upper respiratory airways (7-11). Jaw-repositioning mouthguards may have similar effects on the airways in athletes lending to improved aerobic performance. The effects of two jaw-repositioning mouthguards on aerobic dynamics at rest and during a graded treadmill test in male athletes were evaluated. No significant differences between the jaw-repositioning mouthguards and the controls were observed in respiratory functional tests, ventilation, gas exchange, or maximal aerobic performance. These results indicate that the affordable jaw-repositioning mouthguards did not have any effect, positive or negative, on various performance aspects. This information can be used to encourage mouthguard compliance and dissuade the concerns of performance impediments. Incorporation of advanced dental techniques and individualized design may be necessary to obtain an "optimal jaw position" that promotes positive physical responses. Future research on jaw-repositioning mouthguards should use advanced dental techniques and explore effects on other aspects of physical performance.
