Which statement correctly describes indications for oral sleep appliances in suspected sleep-disordered breathing?

• A. Indicated for severe OSA with no medical clearance
• B. Not indicated for sleep-disordered breathing
• C. Indicated for primary snoring without medical clearance
• D. Indicated for mild-to-moderate OSA or primary snoring with medical clearance; requires sleep study and physician collaboration

Answer: (D)

Oral sleep appliances are appropriate only when there is a confirmed, non-severe sleep-disordered breathing condition and there is medical oversight. These devices move the lower jaw forward to help keep the airway open during sleep, which can reduce snoring and mild-to-moderate obstructive sleep apnea. They should be used after a sleep study confirms the diagnosis and severity, and with collaboration from a physician to ensure safety and appropriateness. Severe obstructive sleep apnea or lack of medical clearance means another treatment path (like CPAP or other therapies) is more suitable. Primary snoring or sleep-disordered breathing without a confirmed, milder diagnosis also wouldn’t be the right context for initiating this therapy.
