 Obstructive sleep apnea is an inflammatory, chronic, and evolutive disease often needing adequate treatment and follow-up. The oral appliance (OA) is an accepted alternative therapy for obstructive sleep apnea (OSA) control. Due to greater adherence, OA with mandibular advancement (OA) is being recommended treatment for patients who refuse or do not tolerate continuous positive airway pressure. The mode of action of OA is to promote the advancement of the mandible or tongue with a subsequent increase in the tone of the pharyngeal muscles and the permeability of the upper airway, but most OA use conventional models as reference, analogic, or digital, dissociating dental arches of the skull structures.
