What Is a Sleep Appliance?
A sleep appliance — also called a mandibular advancement device (MAD) or oral appliance — is a custom-fitted device similar in appearance to a night guard or sports guard. Worn during sleep, it gently repositions the lower jaw slightly forward, which opens the airway, reduces airway collapse, and decreases snoring and the apnea events associated with obstructive sleep apnea.
Sleep appliances are a well-established alternative to CPAP therapy for patients with mild to moderate obstructive sleep apnea — and for many patients, far more comfortable and practical to use consistently.
