A mandibular repositioning device (MRD) is sometimes used to treat
obstructive sleep apnea (OSA) and snoring. The device pushes the tongue and jaw forward.
This makes the airway larger and improves airflow. The MRD also reduces the
chance that tissue will collapse and narrow the airway when you breathe in. You
wear the device every night to prevent breathing problems.
A dentist or orthodontist who has experience with these devices must
fit the MRD to your mouth. You may need go back to your dentist for regular
checkups to make sure the device continues to fit well.
An MRD used by a child with sleep apnea must be refitted periodically
as the child grows.
