The invention relates to devices designed to be used in conjunction with continuous positive airway pressure devices in order to improve the performance of the positive airway pressure in treating a disorder in breathing during sleep. In one embodiment, connection points on each side of both a maxillary and mandibular bite form are connected in order to maintain a space between the teeth substantially equal to the maximum intercuspal distance or space. Used with available continuous positive airway pressure devices, the invention can substantially improve obstructive sleep apnea or similar treatments with lower failure or patient non-compliance rates.
