All patients had worn complete dentures for at least 1 year; all patients had the dentures modified to a MAD. Five variables were assessed preoperatively and 6 months after wearing the modified MADs. These variables were: sleep efficiency, AHI, oxygen desaturation events\/hr., mean oxygen saturation, snoring index, and airway volume. This assessment was done by subjecting the patients to all\u2010night polysomnography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Without any prosthesis or device in the edentulous patients, the mean velopharyngeal volume was 8.05 \u00b1 0.58 cm<jats:sup>3<\/jats:sup>, oropharyngeal volume was 2.14 \u00b1 0.38 cm<jats:sup>3<\/jats:sup>, and hypopharyngeal volume was 3.26 \u00b1 0.78 cm<jats:sup>3<\/jats:sup>. With complete dentures (unaltered) in the edentulous patients, the mean velopharyngeal, oropharyngeal, and hypopharyngeal volumes were 10.73 \u00b1 0.98 cm<jats:sup>3<\/jats:sup>, 2.60 \u00b1 0.48 cm<jats:sup>3<\/jats:sup>, and 4.31 \u00b1 0.89 cm<jats:sup>3<\/jats:sup>, respectively. There was a statistically significant change in the airway volume following insertion of the complete dentures modified as MADs with velopharyngeal, oropharyngeal, and hypopharyngeal volume recorded as 11.76 \u00b1 1.07 cm<jats:sup>3<\/jats:sup>, 3.33 \u00b1 0.51 cm<jats:sup>3<\/jats:sup>, and 4.94 \u00b1 0.83 cm<jats:sup>3<\/jats:sup>, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>From the results obtained in this limited small sample study, it was inferred that the pharyngeal expansion induced by complete dentures modified as MADs effectively reduced symptoms of OSA.
