Summary

Mouthguards reduce uneven bite forces on teeth during sports, offering better protection. Hardness of the mouthguard did not significantly impact force distribution.

Area of Science:

  • Dental Science
  • Sports Medicine
  • Biomechanics

Context:

  • Traumatic injuries in the maxillofacial region are common during sports.
  • Mouthguards are widely used to prevent such injuries.
  • Understanding occlusal force distribution is crucial for evaluating protective devices.

Purpose:

  • To investigate the influence of wearing mouthguards on occlusal force distribution.
  • To compare occlusal force distribution with natural dentition and a conventional bite plane.
  • To analyze the effect of mouthguard hardness on force distribution.

Summary:

  • Wearing mouthguards reduced the difference in average occlusal force level (OFL) within the same dental arch.
  • No statistically significant difference in OFL was found between mouthguards of different hardness.

  • During a three-second clenching task, OFL in the posterior region showed initial fluctuation but stabilized.

    • Impact:

    • Mouthguards enhance occlusal force distribution, potentially improving their effectiveness in preventing sports-related injuries.
    • The findings suggest that mouthguard hardness may not be a critical factor in optimizing force distribution.
    • This research provides valuable data for the design and selection of sports mouthguards.
