Obstructive Sleep Apnea (OSA) is a medical diagnosis made with a sleep test. Continuous Positive Air Pressure (CPAP) mask is indicated for severe OSA (AHI > 30 from sleep test). CPAP is not needed for snoring, which is best treated with an Oral Appliance.
Oral appliances are worn during sleep to keep airway open to reduce its collapsibility by making room in the mouth for the tongue. View the video below to learn more about the real life experience of a Chiropractor and her appliance.
American Academy of Sleep Medicine’s Practice Parameters states: “Oral Appliances (OAs) are indicated for use in patients with mild to moderate OSA who prefer them to CPAP therapy, or do not respond to, are not appropriate candidates for CPAP, or
fail treatment attempts with CPAP.” (1)
“Oral appliances are a simpler alternative to CPAP. Over the last decade, there has been a significant expansion of the evidence base to support the use of oral appliances, with robust studies demonstrating their efficacy.” (2)
Studies on Oral Appliance (OA) include:
- Oral appliance therapy for obstructive sleep apnea over 4 weeks results in a reduction in blood pressure, similar to that reported with CPAP. (3)
- OA were less effective than CPAP based on sleep study numbers. However, no significant difference was observed on symptom scores.(4)
- OA appear to be used more (at least by self report), and in many studies were preferred over CPAP when the treatments were compared (5).
- OA is an effective treatment in some patients with mild-moderate OSA and is associated with fewer side effects and greater patient satisfaction than N-CPAP (6).
Different types of oral appliances are available for different purposes. For more information, see Oral Appliance Therapy: The Whole Health Way.
