  • Providing sources of less viscous heat-softenable material in structures— i.e., as protrusions 24— that are not required to maintain the general integrity of the mouthguard can introduce the relatively more flowable heat-softenable materials into the mouthguard 10 in a way that does not compromise the integrity of the form of the mouthguard 10 as a whole during the custom fitting process.

  • a protrusion 24 may be generally semi-conical, possessing more heat-softenable material near the base 12 and tapering as the protrusion 24 extends upward along the wall 14.
  • the rounded surface may provide comfort while the mouthguard 10 is being fitted.

  • One benefit is a more complete and individualized fit for the mouthguard 10.
  • a more complete and individualized fit can result in increased comfort for the user, which can increase the likelihood that a user will wear the mouthguard 10 as designed and, therefore, enjoy that maximum performance and/or protective benefit of using the mouthguard 10.
  • Better fit also improves the likelihood that the mouthguard 10 will remain in the intended, proper position when in use. This, too, increases the likelihood that the user can enjoy the maximum performance and/or protective benefit of using the mouthguard 10.
  • Another consequence of the mouthguard 10 remaining in its intended, proper position is that the mouthguard 10 may be less exposed to the user removing and chewing on the mouthguard 10, which can promote delamination of mouthguard components and/or premature destruction of the mouthguard 10.
  • protrusions 24 Another benefit that may be provided by the protrusions 24 includes addition material providing performance benefits such as, for example, impact absorption.
  • Impact force may originate from, for example, impacts, collisions, and/or blows associated with athletic competition and/or clenching stress. Regardless of the source of the impact force, additional impact absorption capacity provided by additional heat-softenable material can improve the performance and/or protection offered by the mouthguard 10 and, therefore, improve the performance of the user.
