The Moses

5008428d12c7dfd4b266dea7146046ec_ir0t_z98vThe Moses® appliance has been shown to be the most effective oral airway dilator available for dentists to use in the treatment of obstructive sleep apnea (OSA). By incorporating tongue management, the Moses appliance has improved on the effectiveness of simple mandibular advancement splints. The Moses appliance has been shown to activate reflexes to advance the tongue, lower elevator muscle activity, reduce clenching and decrease bruxism. The two part design is very comfortable, allowing the patient to close their lips, talk and even sip water.

The Moses appliance was invented by Dr. Allen Moses DDS, DABCP, DABDSM. Dr. Moses holds a faculty appointment as an assistant professor of Rush University Medical School in the Department of Sleep Disorders. He is a Diplomate of both the American Board of Cranio-facial Pain and the American Board of Dental Sleep Medicine.

Dr. Moses selected Modern Dental Laboratory USA as exclusive manufacturer and distributor of the Moses appliance world-wide.
The Moses® appliance 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

  • Activates tongue protruding reflexes resulting in tongue advancement
