Prevalence and Clinical Significance of Supine-Dependent Obstructive Sleep Apnea in Patients Using Oral Appliance Therapy

摘要

Study Objective: The prevalence of supine-dependent obstructive sleep apnea (sdOSA) in a general population ranges from 20% to 60%, depending on the criteria used. Currently, the prevalence and evolution of sdOSA once oral appliance therapy with a mandibular advancement device (OA(m)) has started is unknown. In addition, literature on the correlation between sdOSA and treatment success with OA(m) is not unequivocal. The first purpose of this study was to assess the prevalence of sdOSA before and under OA(m) therapy. Second, the conversion rate from non-sdOSA to sdOSA during OA(m) therapy was evaluated. The third and final goal was to analyze the correlation between sdOSA and treatment success with OA(m) therapy in the patient population.
