An oral sleep apnea device is a dental appliance designed to advance the lower jaw of a user suffering from sleep apnea while reducing lingual discomfort and the risk of harmful tooth movement and rotation during use. The present invention accomplishes this through the use of a maxillary and a mandibular dental plate coupled to the upper and lower jaw, respectively, without direct contact with the incisal or labial surfaces of the anterior teeth. Both appliances comprise a lingual surface mount. The maxillary dental plate comprises an advancement mechanism. The advancement mechanism being operatively engaged to the mandibular dental plate repositions the mandibular plate to a forward location relative to the maxillary dental plate. During the repositioning of the mandibular dental plate the mandibular lingual surface mount distributes pressure evenly to the lingual surfaces on the lower jaw, reducing localized pressure points which can cause tooth movement.
