Adherence and Preference of Continuous Positive Airway Pressure Versus Mandibular Advancement Splints in Obstructive Sleep Apnea Patients: A Randomized Trial (CHOICE)
Obstructive Sleep Apnea
About this trial
This is an interventional treatment trial for Obstructive Sleep Apnea focused on measuring Adherence, CPAP, Oral Appliance, Mandibular Advancement Splints, Preference
Eligibility Criteria
Inclusion Criteria:
You may be able to participate in this study if:
- You are naïve to treatment (never used CPAP or oral appliance, nor had surgery for sleep apnea);
- You are between 19-75 years old;
- You have a Body Mass Index (BMI) ≤ 35;
- You have enough teeth (at least 8 per arch) for MAS;
You have:
- an Apnea-Hypopnea Index (AHI) within the range 10 ≤ AHI ≤ 50 documented with polysomnography in the last 2 years; ***OR***
- a Respiratory Disturbance Index (RDI) within the range 20 ≤ RDI ≤ 50 documented with level III portable sleep test; ***OR***
- an Oxygen Desaturation Index (ODI) ≥ 10; and
- You have had a sleep test within the past 2 years.
Exclusion Criteria:
You may not be able to participate in this study if:
- You have extensive periodontal disease with significant tooth mobility (disease around your teeth);
- You are unable to protrude the jaw (unable to extend your jaw);
- You have a lack of a sufficient vertical opening to accommodate an appliance;
- You have uncontrolled congestive heart failure (defined as a prior clinical diagnosis, an ejection cutoff of 40% or a clinical sign in the opinion of a primary care physician or cardiologist) that makes it unsafe for you to participate in the trial in the opinion of the investigators;
- You have coronary artery disease unless stable for at least 6 months and considered by the investigators to have a stable disease;
- You have a history of angina (chest pain when your heart does not get enough blood), myocardial infarction (heart attack) or stroke;
- You have a history of major depressive disorder (such as bipolar disorder) along with current moderate or severe disease;
- You have cancer unless in remission (decreasing signs of your cancer being present) for more than 1 year;
- You have known renal (kidney) failure with need for dialysis;
- You are pregnant (if a female participant becomes pregnant during the trial, she will be withdrawn from the study);
- You have had a near miss or prior automobile accident due to sleepiness within the past 12 months; and/or
- At nighttime, 30% of the night is at ≤ 90% oxygen saturation levels.

Active Comparator
MAS-PAP
PAP-MAS
Mandibular advancement splints (MAS): dental splints used to keep the mandible in an advanced position opening the upper airway during sleep; followed by positive airway pressure (PAP)
Positive airway pressure (PAP): a device which consists of a face mask attached to a plastic tube and a machine that blows compressed air through a patient's airway during sleep to keep the airway open; followed by mandibular advancement splints (MAS)
