The objective of this study is to assess the efficacy of the Orthoapnea NOA mandibular advancement device and describe the percentage of advancement (%) needed to reach efficacy, and to retrospectively compare with other MAD designs in the management of obstructive sleep apnea. Additionally, to describe patient compliance and adherence to the therapy with the Orthoapnea NOA device, and to assess the incidence and prevalence of signs, symptoms, and diagnosis of temporomandibular disorders (TMD) associated to the use of the Orthoapnea NOA mandibular advancement device.
