CMOA is a customized maxillary removable oral appliance with a “base plate” and the “counter plate.” The base plate was adjusted over the upper jaw taking support of hard and soft tissues that is namely teeth and hard palate. The counter plate is adjusted over the base plate with a space of 2 mm in between the two plates. The space between these two plates was made empty or hollow. The upper plate had the anatomy of the occlusal surface of the upper teeth for occluding with the lower teeth in present occlusal relation but at an increased vertical dimension that is attained by hollowing the plate. The hollow upper plates had an opening or a hole in the central incisor area that is in the anterior region, for the uninterrupted instreaming of the fresh air towards the posteriors region of the tongue. Moreover, a bulge was outlined on the upper plate on the palatal aspect of the appliance in the most posterior back region to restrain the tongue from fallback.Frontal view of CMOA placed intra-orallyLateral view of CMOA placed intra-orally
