Efficacy of mandibular advancement devices in two patients with moderate obstructive sleep apnea: Case reports

Abstract

Oral appliances are an alternative to continuous positive airway pressure (CPAP) for thetreatment of obstructive sleep apnea (OSA). Mandibular advancement device (MAD) is apopular treatment alternative particularly for mild to moderate OSA . Polysomnographic (PSG)evaluation were performed on two patients before and about one year after continuous use ofthe MADs. The results were compared. In the first case, the apnea-hypopnea index (AHI) beforetreatment was 22.0 and decreased, to 4.3, after one year of treatment. After one year, the AHIdiffer significantly from the pretreatment value. In the second case, before treatment, the AHIwas 21.4 and decreased to 10.1 after one year of treatment. The one year follow-up showedthat occlusion was preserved, masticatory muscles and temporomandibular joint (TMJ) wereprotected. The MADs reduced apneas and improved sleep quality in patients with OSA .
