Clinical trial for Sleep

Official title Impact of a Mandibular Oral Repositioning Device on Sleep Quality, Heart Rate Variability, & SpO2

ClinicalTrials.gov ID: NCT07359638

What this study is testing

What it's testing
The study compares a jaw‑advancing oral device with a neutral placebo to see if it changes sleep stages, heart‑rate variability, and blood‑oxygen levels.
Who it's for
Healthy adults who have trouble sleeping or feel fatigued after sleep
What's involved
Participants will wear two custom‑made devices, one that gently moves the lower jaw forward and one that keeps it neutral, while a wrist‑worn monitor records sleep, heart‑rate variability, and oxygen saturation. They will also fill out short questionnaires and sleep logs.
Time commitment
The study lasts about 12 weeks, including a baseline period, two device phases with a washout in between, and a brief follow‑up, with regular sleep‑monitoring and questionnaire completion.
