An anti-obstructive airway dental orthotic is described. The orthotic includes a maxillary retainer and a mandibular retainer releasably attaching to a plurality of teeth of a wearer. The retainers are attached by at least one strut, either variable in length or of a plurality of lengths, which exert a forward force on the lower jaw, tending to advance the mandible relative to the maxilla. This advancement of the lower jaw promotes a less obstructed airway in the wearer, while fenestrations in the retainers may allow for greater comfort and tongue movement.
