(0.PSG): First-night polysomnogram without using any appliance so as the baseline severity of OSA to be determined.
(PSG.M1): The first week of control polysomnogram performed to group MAS following 1-week insertion of the mandibular advancement splint appliance.
(PSG.M2): Third control polysomnogram after one-month usage of MAS appliance.
