Jaw muscle signals may predict unwanted tooth shifts from sleep apnea devices

NCT ID NCT06576310

First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time

Summary

This study investigates whether measuring jaw muscle activity can predict dental changes caused by mandibular advancement devices (MADs) used for obstructive sleep apnea. About half of people stop using MADs due to unwanted tooth movements. Researchers will track 118 adults over six months, using surface electromyography and digital bite analysis to see if muscle patterns correlate with dental shifts. The goal is to identify who is at risk and tailor treatment to reduce side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a mandibular advancement device (MAD) — a custom oral appliance that moves the lower jaw forward to keep the airway open during sleep
What this could lead to
If successful, this could help dentists predict which sleep apnea patients will experience unwanted dental shifts from a mandibular advancement device, allowing for personalized adjustments and fewer treatment dropouts.
What could go wrong
This is an observational study, not a test of a new treatment. It focuses on predicting side effects, not on curing or controlling sleep apnea itself. Results may not apply to all patients or devices.
