An observational study in Obstructive Sleep Apnea (OSA) and Oral Applliance Therapy, sponsored by Nevada Dental Sleep. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-08.
Sponsored by Nevada Dental Sleep · Observational
Prospective, real-world observational study in a dental sleep practice to assess the feasibility of incorporating the PLATO into a dental sleep practice and applicability for patients who are undergoing oral appliance therapy for the treatment of obstructive sleep apnea(OSA).
The PLATO questionnaire was recently developed by the American Academy of Sleep Medicine specifically for use in patients with obstructive sleep apnea.
2,240 studies on the registry are indexed under Sleep Apnea, Obstructive; 475 are open to participants now.
This study's planned enrollment of 20 is below the median of 105 across 666 observational studies indexed under Sleep Apnea, Obstructive.

Individuals who are referred by a qualified healthcare provider to the dental sleep clinic will be approached to participate. The community is located in Henderson, Nevada. The dental sleep clinic is a private dental sleep clinic located in a medical complex. Typically, most referrals come from within the community at large. The practice also treats individuals who are in the military (VA, active duty, special ops etc)
Inclusion Criteria:
Inclusion Criteria
Exclusion Criteria:
Patients who have been diagnosed and prescribed a custom fabricated oral appliance/mandibular advancement device (Panthera D-SAD) for the treatment of mild to moderate obstructive sleep apnea or those who are severe, who decline to use a continuous positive airway pressure (CPAP) device.
Other: The study will assess the feasibility of incorporating the PLATO questionnaire into a dental sleep practice. The PLATO questionnaire was developed as a patient reported outcome measure
The primary outcome will be to assess the difference in pre and post (within subject) scores on the PLATO questionnaire in a population of patients with a diagnosis of obstructive sleep apnea who will be treated with an oral appliance.
Change from baseline of the PLATO questionnaire at the completion of the oral appliance titration period.
The PLATO questionnaire is a patient reported outcome measure. The questionnaire will be completed prior to the beginning of the therapy, until the dental practitioner, based on subjective and objective measures determine that the optimum position to treat the sleep apnea has been attained. Minimum Value: 0 Maximum Value: 50 Outcome Interpretation: Higher scores indicate a worse outcome (more severe obstructive sleep apnea symptoms and greater daytime fatigue)
Time frame: The time from enrollment unit completion is as follows: Initial assessment to device delivery 10-30 days, after delivery the time depends on the participants response, which can be between 30-90 days.
Plan to share: No — For this study, it does not require the data to be shared.
Started Oct 2026 (actual). Primary completion is estimated for Dec 2026, 2 months after the start.
Of 258 non-industry observational studies under Sleep Apnea, Obstructive, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 61. This study's planned 2 months is below that.
Counting every sponsor, half of 294 studies reached it within 28 months; a quarter within 14 and three quarters within 63.
Start moved once since we started tracking on Sep 25, 2026: Sep 2026 → Oct 2026, on Oct 8, 2026.
