Oral Appliances for Sleep Apnea

Oral appliance therapy (OAT) is an effective treatment option for patients with mild to moderate obstructive sleep apnea (OSA). Although continuous positive airway pressure (CPAP) therapy is the first line of treatment for sleep apnea, many patients prefer an oral appliance to CPAP. An oral appliance is a small plastic device that fits in the mouth like a sports mouth guard or orthodontic retainer. Oral appliances help prevent the collapse of the tongue and soft tissues in the back of the throat, keeping the airway open during sleep and promoting adequate air intake. Oral appliances may be used alone or in combination with other treatments for sleep-related breathing disorders, such as weight management, surgery or CPAP.
