The author has treated over 2,000 patients with SAS using mainly oral appliances [9, 19, 22, 39]. The patients sometimes experienced a transitory discomfort of the masticatory muscle or temporomandibular joint, excessive salivation, and transient tooth discomfort after first using the device. It would be very meaningful to develop a new treatment device with fewer complications for safe and long-term use. The author aims to develop a device which allows free jaw movements during sleep and advance the mandible if sleep apnea occurs based on respiratory pattern sensoring. The device could be combined with CPAP. When sleep apnea occurs, the device protrudes the mandible, and even if the apnea disappears, the positive airway pressure additionally works to diminish any remaining upper airway obstruction. The device could minimize the airway pressure because it prevents patients from mouth breathing, air-leak, and upper airway collapse by advancing the lower jaw. Many patients with severe SAS have been intolerant to CPAP because of discomfort related to the high pressure sensation and air-leak. This device will be highly beneficial for such patients and patients with poor compliance with standard CPAP or other oral appliances [124].
