AbstractA mouthguard that has a body having upper and lower troughs conforming generally to the upper and lower arches. Liners of impression material are disposed in the respective troughs for conformance to the actual impressions of the teeth of the arches. The body has an occlusal wall that contains a series of spaced-apart air/saliva ducts extending in a lingual/buccal sense to establish lingual/buccal fluid communication. The liners are mechanically interlocked to the mouthguard body by interlocking material that extend along the edges of the respective troughs and also by integral connections which extend through the occlusal wall between the two troughs in bridging portions of the occlusal wall that separate the air/saliva ducts.
