The brain alerts the body to its lack of oxygen, causing a brief arousal from sleep that restores normal breathing. The result is a fragmented quality of sleep that often leads to excessive daytime sleepiness.
Most people with OSA snore loudly and frequently, with periods of silence when airflow is reduced or blocked. They then make choking, snorting or gasping sounds when their airway reopens.
Custom made oral appliances reposition the tongue and lower jaw forward during sleep to maintain an open airway. Dentists trained in dental sleep medicine know how to select, fabricate, fit and adjust these devices, which look like mouth guards, to help patients breathe freely during sleep.
Follow-up visits and post adjustment sleep studies help dentists determine if oral appliance therapy is effectively treating their patients' sleep apnea.
Dentists are not permitted to diagnose sleep apnea. Diagnosis should be done at an accredited sleep center (www.sleepcenters.org.).
Oral Appliance Therapy is indicated for mile to moderate OSA patients if they prefer it to Continuous Positive Airway Pressure (CPAP), the standard treatment therapy, cannot tolerate CPAP, or are unable to use positional therapy or weight loss to control their apnea.
Oral appliances are also recommended for severe OSA patients if they cannot tolerate CPAP. Patients with severe OSA should always try CPAP before considering oral appliance therapy.
Did you know that 25 to 50 percent of sleep apnea patients do not comply with or tolerate CPAP?
