Snoring and Sleep Apnea

These are the findings of one of our patients whom is using a sleep apnea appliance:


“The overnight study showed evidence for short episode of soft snoring in the end of the night without significant breathing disturbances. Her arterial blood oxygen saturation was within normal limits. Good response to dental appliance. The sleep EEG showed some difficulties in maintaining sleep with changes in sleep architecture consisting of a frequent periodic EEG sleep disorder (cycling alternating pattern) with mild impairment in sleep efficiency.”

The SomnoDent® MAS


The SomnoDent® MAS is a Mandibular Advancement Splint (MAS) that treats mild, moderate and severe OSA by moving the lower jaw slightly forward. This movement tightens the soft tissue and muscles of the upper airway, which prevents obstruction while you sleep. The SomnoDent® MAS also prevents the tissues of the upper airway from vibrating as air passes over them, which is the major cause of snoring.
