Using a mouth guard to help prevent sleep apnea

Intervention to Enhance Adherence to Mandibular Advancement Appliance in Patients With Obstructive Sleep Apnoea: A Randomized Control Trial

Not applicable Interventional Queen Mary University of London · NCT04092660

This study is testing if a special mouth guard can help people with sleep apnea breathe better at night and if extra support can encourage them to use it more often.

What this trial studies

This study evaluates the effectiveness of a Mandibular Advancement Appliance (MAA) in patients with Obstructive Sleep Apnea (OSA) and whether additional support interventions can increase its usage compared to standard care. Participants aged 40 and older with a confirmed diagnosis of OSA will be randomly assigned to either an intervention group, receiving extra support and education, or a control group receiving standard care. The study will also explore factors influencing patients' adherence to using the MAA, including psychological and social aspects. Data on usage will be collected through sleep diaries and sensors in the appliance.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40 and older with a confirmed diagnosis of obstructive sleep apnea who are referred for MAA therapy.

Not a fit: Patients with insufficient teeth for MAA fabrication, poor dental health, symptomatic temporomandibular disorder, or a history of epilepsy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved adherence to MAA therapy, enhancing treatment outcomes for patients with obstructive sleep apnea.

How similar studies have performed: Previous studies have shown that behavioral interventions can improve adherence to treatment in similar patient populations, suggesting potential success for this approach.
