Clinical Trial Summary

The purpose of this study is to compare the cost-effectiveness and effectiveness of mandibular repositioning appliance (MRA) versus Continuous positive airway pressure (CPAP) therapy in patients with moderate Obstructive Sleep Apnea Syndrome (OSAS).


Clinical Trial Description

Study design: In a randomized parallel controlled study 86 patients will be randomly assigned to either MRA therapy or CPAP therapy. Group A receives MRA. Group B receives CPAP. The total duration of the study is 12 months. Measurements will be done at baseline, after 3, 6 and 12 months.

Intervention: Group A will be treated with a bibloc MRA (Somnodent). The mandible will be set at 70% of the patient's maximum advancement and will be adjusted to the convenience of the patient. Titration will be continued until symptoms abate or until further advancement causes discomfort.

Group B will be treated with CPAP. Proper CPAP-pressure will be set for each patient separately. Patients are fitted with a comfortable CPAP mask before titration of the CPAP-pressure. For CPAP-titration, patients are instructed to adopt their own typical sleeping habits. ;
