A mouthpiece for oral delivery for oral delivery of CPAP treatment has a
vestibular shield for location between the teeth and lips/cheeks of a
wearer. The vestibular shield is formed from a very supple material and is
dimensioned to extend laterally into the buccal vestibule and vertically
to overlap the gums. A gases pathway is provided through the vestibular
shield and may include a hard plastic insert through the shield. A
connection for connecting the mouthpiece to a breathing circuit is
provided which reduces the transfer of forces caused by movement
therebetween.
