NAPA
SLEEP APNEA
The Nocturnal Airway Patency Appliance, or NAPA, is very effective in reducing the signs and symptoms of both OSA and snoring. The NAPA is a monoblock appliance that uses delta clasps for retention and has an anterior mouthpiece. A construction bite taken in a forward position with a minimum of 5mm between the incisors is necessary to fabricate the NAPA.
In moderate to severe OSA, 80% of the patients received good to excellent results with the NAPA. In non-OSA snoring, 95% of those sleeping with a NAPA found their nighttime noise is stopped or greatly reduced. NAPA is one of the industry’s early sleep designs and Johns Dental has had significant success with the NAPA through the years.
