Treatment with a mandibular advancement device (MAD) is recommended for mild obstructive sleep apnea (OSA), primary snoring and as a secondary option for Continuous Positive Airway Pressure, because it has better adherence and acceptance. However, edentulous patients do not have supports to hold the MAD. This study aimed to present a possible to OSA treatment with MAD in over complete upper and partial lower dentures. The patient, a 38-year-old female with mild OSA, was treated with a MAD. The respiratory parameter, such as apnea-hypopnea index, arousal index and oxyhemoglobin saturation was improved after treatment.

Mandibular advancement device (MAD) has been described as an alternative treatment to the severe obstructive sleep apnea (OSA), once it is not as effective as the continuous positive airway pressure therapy (CPAP) in reducing the apnea and hypopnea index (AHI). The objective of this study is to report a case using a MAD in a CPAP-intolerant patient suffering from severe OSA. Polysomnography exams were performed before and after treatment. Five months after fitting and titrating the MAD, the AHI was reduced from 80.5 events/hour to 14.6 events/hour and the minimum oxyhemoglobin saturation (SpO2) increased from 46% to 83%. A two-year assessment of therapy revealed an AHI of 8 events/hour and SpO2 of 85%.

The cone beam computed tomography (CBCT) image provides clear differentiation of soft tissues from empty spaces. This paper presents a literature review to evaluate the effects of orthopedic and surgical treatment on the pharyngeal dimension by CBCT. It was concluded that treatments involving dentofacial orthopedics and orthognathic surgery have been related with an increase in the upper airway volume. Standardized capturing of tomographic images and more controlled and randomized studies are necessary.
