摘要：
A mouthpiece having a vestibular shield overlapping a user's teeth and gums, a gases passageway extending through the vestibular shield allowing for the passage of the gases through the mouthpiece and an extra oral sealing member is associated with the gases passageway. The passageway in use causes gases to be diffused when exiting from the gases passageway. The mouthpiece may have a noseflap to seal the user's nose or provide a passageway for the user's nasal passages. The mouthpiece may have an adjustment arrangement to alter a distance between the vestibular shield and the extra-oral sealing member.
