About this study
Official title: Evaluation of the Effects of Mandibular Advancing Device in Obstructive Sleep Apnea Patients
The goal of this clinical trial is to learn if Mandibular advancing devices work to treat obstructive sleep apnea in adults. Selected Participants have a mild or moderate degree of obstructive sleep apnea.The main questions it aims to answer are:
Do Mandibular advancing devices (MADs) lower the number of times participants experience apneas or hypopneas during sleep? Do MADs lower Apnea Hypopnea Index in adults when worn during sleep?
Read the detailed description
This clinical trial aims to evaluate comprehensively the effects of a custom made titrable bi-block mandibular advancing device on the respiratory variables in polysomnography. This includes the apnea hypopnea index and the oxygen desaturation index. Also sleep variables such as sleep efficiency and snoring duration are evaluated. Also cone beam computed tomography scans are taken before treatment and after 6 weeks of using te appliance. the second CBCT scan is taken with the appliance intra-orally. The cahnge in airway volume and minimal axial area are measured.

Who may be eligible to take part?
The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
change in AHI (time frame: frpm enrollment to assessment of outcomes at least 8weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jun 2025.
