• Daytime Sleepiness (ESS)
  
• Apnea/Hypopnea Index (AHI)

Patients will be enrolled into the study based on sleep study results, a physical exam and inclusion/exclusion criteria. Once enrolled, patients are randomized into either the Pillar palatal implant group or a placebo/sham group.

In both cases, patients come into the office for placement of the implants. This is an outpatient procedure. Patients are followed at one week, one month and 3 months. At each follow-up visit, patients will undergo a physical exam and complete questionnaires related to sleep and quality of life. Patients will also undergo reaction time testing on hand-held device similar to a pocket video game. At the three month visit, patients will return to the sleep lab for another sleep study.
