Do sleep apnea oral appliances actually work?

The evidence base is solid. A 2015 Cochrane review of randomized controlled trials found MADs significantly reduce apnea-hypopnea index scores and improve oxygen saturation compared to inactive controls. AASM and AADSM guidelines both recognize oral appliance therapy as a first-line treatment for mild-to-moderate OSA and as a CPAP alternative for patients with severe OSA who refuse or fail CPAP. Compliance data consistently show patients wear appliances 6 or more hours per night versus 4 to 5 hours for CPAP in the same populations.

For prescribing dentists, the practical question is appliance quality and titration range. A custom-fabricated device with 10 to 12 mm of protrusion range outperforms thermoplastic over-the-counter devices in every published fit and efficacy comparison. The fabrication workflow matters too: accurate impressions or digital scans sent to a lab that maintains tight vertical dimension tolerances produce appliances that seat correctly from night one, reducing chair time on adjustments from multiple visits to one or two.

Dani Dental fabricates sleep appliances from digital or physical impressions with a standard 5-business-day turnaround. Each device ships with the technician's direct contact for fit questions, so prescribing dentists are not left coordinating adjustments through a general support queue. For practices adding sleep therapy as a revenue line, that direct-line accountability shortens the titration cycle and keeps patients on track toward their follow-up sleep study.
