Dental Appliance in Severe Sleep Apnea

Dental appliances (mandibular advancement devices) are traditionally recommended primarily for mild-to-moderate obstructive sleep apnea, with CPAP reserved as the first-line treatment for severe cases. This article reviews the evidence for their use in severe OSA as well.

While CPAP remains highly effective for severe obstructive sleep apnea, real-world adherence rates are often lower than desired. This has led clinicians to reconsider dental appliances as a viable option for select severe cases, particularly when CPAP is not tolerated.

Studies and clinical experience show that a meaningful proportion of patients with severe OSA achieve significant improvement in breathing indices with a well-fitted, properly titrated dental appliance, even if the reduction is sometimes less complete than with CPAP.

For patients who cannot tolerate CPAP, or who prefer a smaller, quieter, more portable solution, a carefully monitored trial of a dental appliance – with follow-up sleep testing to confirm efficacy – is a reasonable clinical path even in severe cases.

Prof. Yaron Haviv evaluates each severe case individually, combining sleep study data with careful appliance titration to maximize outcomes.
