The etiology is multifactorial, mainly associated with obesity, craniofacial abnormalities and systemic diseases due to this therapy is multidisciplinary, requiring the exams for modified Mallampatti classification, Epworth Sleepiness Scale and polysomnography for the diagnosis and evaluation of severity of SAOSH. The objective of this study is to detail the importance and the main snoring plates in treating SAOSH through the literature review. The intraoral devices (AIOs) are conventional therapeutic modalities employed in very mild OSAS in patients with moderate, especially with mandibular advancement device (MAD), which provides initial patient comfort and improves the quality of sleep and life.
