Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study measured dental movements in 180 adults with sleep apnea who use an oral appliance. Researchers used 3D photographs of teeth to track changes in tooth rotation and length. The goal was to better understand how these devices affect tooth position over time.

What this could mean

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

Active substance
oral appliance (dental device)
What this could lead to
If successful, this could help dentists and sleep specialists better predict and manage tooth movements caused by oral appliances for sleep apnea.
What could go wrong
This is an observational measurement study, not a treatment trial. It only looks at dental changes and does not test any new therapy or device.
