The “Moses” appliance is properly categorized as a mandibular advancement device (MAD). A “Moses” is an acrylic appliance that is worn in the mouth at night to treat obstructive sleep apnea, hypopnea, upper airway resistance and snoring. It is custom-fitted and laboratory fabricated.

The MAD works in the following ways:
  • Supports the lower jaw in a forward position of low muscle activity and it prevents collapse of the tongue on the pharynx
  • Increases volume of space for the tongue in the mouth
  • Dilates pharyngeal muscles, lifts the drooping soft palate
  • Raises the position of the hyoid bone relative to cranial base
  • Lowers elevator muscle activity, reduces clenching, decreases or prevents bruxism
Additional, advantages of the “Moses” appliance:
  • Open anterior facilitates a forward tongue position against the lips
  • Elevates tongue to hard palate and increases nasal air flow
  • Allows lip seal
  • Corrects dysphagia
  • Comfortable and adjustable
