Mandibular Advancement Appliance for Obstructive Sleep Apnea Treatment

A combination of abnormal anatomy and physiology of the upper airway can produce its repetitive narrowing during sleep, resulting in obstructive sleep apnea (OSA). Treatment of sleep-breathing disorder ranges from lifestyle modifications, upper airway surgery, continuous positive airway pressure (CPAP) to the use of oral appliances. A proper treatment selection should be preceded by thorough clinical and instrumental examinations. The type and number of specific oral appliances are still growing. The mandibular advancement appliance (MAA) is the most common type of a dental device in use today. The device makes the mandible protrude forward, preventing or minimizing the upper airway collapse during sleep. A significant variability in the patients' response to treatment has been observed, which can be explained by the severity of sleep apnea at baseline and duration of treatment. In some trials, patients with mild OSA show a similar treatment effect after the use of CPAP or MAA. It is worthwhile to give it a try with an oral appliance of MAA type in snoring, mild-to-moderate sleep apnea, and in individuals who are intolerant to CPAP treatment.
