How does a sleep apnea oral appliance work?

The core mechanism is mandibular advancement. By holding the jaw 50-75% forward of maximum protrusion, the genioglossus muscle tension increases enough to keep the airway patent through inspiration cycles. The result is reduced apnea-hypopnea index (AHI) in mild-to-moderate obstructive sleep apnea cases, and documented compliance rates above 70% at 12 months compared to CPAP's reported 50-60% range in the same population.

For general dentists prescribing MADs, the fabrication quality of the device determines how well titration tracks the prescribed position. A poorly fitting appliance drifts from the target advancement measurement, forcing the patient through repeat adjustments and adding chair time. Custom devices built from accurate digital impressions or intraoral scans hold their calibration position reliably across the titration window. Dani Dental fabricates MADs from scanned models with less than 0.2 mm dimensional variance, verified at delivery.

Prosthodontists and restorative-focused GPs managing complex occlusal situations should note that MAD therapy interacts with existing restorations and bite relationships. A lab that understands crown and bridge occlusal planes can flag potential interferences before the device is delivered, not after the patient reports morning soreness at the four-week check. That upstream collaboration cuts remakes and keeps the titration protocol on schedule.
