Brief Summary
The aim of this clinical trial is to apply a new objective titration procedure in obstructive sleep apnea hypopnea syndrome (OSAHS) patients treated with mandibular advancement device (MAD), and to compare this new objective titration procedure with the subjective titration procedure which is commonly used in clinical practice. The remotely intelligent sleep monitoring system (RISMS) will be used in the new objective titration procedure. The main questions it aims to answer are:
- 1.The efficacy of MAD therapy after each titration procedure.
- 2.The titration time efficiency and the improvement of subjective symptoms after each titration procedure.

Outcome Measures
Primary Outcomes (1)
efficacy of MAD therapy
The efficacy of MAD therapy is in terms of AHI (Apnea-hypopnea index) reduction compared to baseline, as well as the number of responders defined as patients with a reduction in AHI of 50% or more compared to baseline, and/or a follow-up AHI of 10 events/hour or less.
The parameter of AHI will be recorded at baseline before the titration and the end of the titration procedures (up to 60 days) using the same PSG device to diagnose OSAHS.
Secondary Outcomes (3)
titration time efficiency
The prescribed time is 60 days. The actual titration time is the time taken from the start to the end of the titration procedures (up to 60 days). The saved time is 60 days minus actual titration day.
Epworth sleepiness score(ESS)
ESS will be determined at baseline and the end of titration procedures (up to 60 days).
Snore Scale(SS)
SS will be determined at baseline and the end of titration procedures (up to 60 days).
Study Arms (2)
objective titration procedure
EXPERIMENTALObjective titration procedure will be based on the objective diagnosis and treatment indicator AHI(Apnea-hypopnea index)which will be provided by RISMS (Remotely intelligent sleep monitoring system). SC-500TM is a comfortable contactless under-mattress sleep monitor, as a main component of the RISMS will be given to patients to collect the sleep data every night at home setting. The sleep report will be generated automatically every day providing the value of AHI and uploaded to the clinicians in real-time. The clinicians will contact the patients by phone every 3-7 days and instruct them remotely to adjust the MAD to increase the mandibular advancement by 0.25-1mm each time, according to AHI together with the self-reported evolution of symptoms. The patients will adapt this new mandibular advancement for 3-7 days and the clinicians will contact them again for further adjustment until a significant improvement of AHI and resolution of symptoms occurs.
subjective titration procedure
ACTIVE COMPARATORThe subjective titration procedure in this study will be based on self-reported evolution of symptoms and physical limits of the OSAHS patients. Patients will be recalled to the hospital every 1-2 weeks and will be asked about the subjective changes such as snoring, daytime sleepiness,ache of tooth, temporomandibular pain and so on. Then, the clinicians will adjust the MAD to increase degree of mandibular advancement by 0.5-1mm each time. The patients will adapt this new mandibular advancement for 1-2 weeks and have to come back to hospital for further adjustment until an improvement or a resolution of symptoms occurs, or until the patients could not tolerate any further advancement.
Interventions
The OSAHS patients referred for MAD treatment will experience either the objective titration procedure or the subjective titration procedure.
