Mandibular advancement splint

A mandibular advancement splint is a special device that you wear in your mouth while you sleep. It helps to keep your jaw pushed forward a bit, which can help to treat certain breathing problems like snoring or sleep apnea.

When you breathe in air while you sleep, it goes through your mouth or nose and down into your throat. But sometimes your tongue or other tissues in your throat can get in the way and block your airway, which makes it hard to breathe.

The mandibular advancement splint works by gently pulling your lower jaw forward so that your airway stays open and unobstructed. That way, you can breathe more easily and sleep better.

The device is made of soft material that fits over your teeth, and it has a hinge that connects the upper and lower parts of the splint. A special key or tool is used to adjust the hinge so that your jaw is in the right position.

Overall, the mandibular advancement splint is a simple, non-invasive way to treat sleep-related breathing issues and improve your overall health and well-being.
