Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a severe and life-threatening disorder that affects both adults and children. It is a breathing disorder characterised by brief interruptions of breathing during sleep as many as 5-80 times per hour. Each time you stop breathing in your sleep, the resulting lack of oxygen alerts your brain, which temporarily wakes you up to restart proper breathing.

Since the time spent awake is so brief, most people with sleep apnea don't remember it, and many feel like they are getting a good night's sleep when, in fact, they are not. The constant wake-sleep, wake-sleep cycle prevents those with sleep apnea from achieving deep sleep, resulting in a constant drowsy feeling during the day.

The gold standard treatment for OSA

Oral Appliance
Oral appliance therapy is recommended by the American Academy of Sleep Medicine as a comfortable and effective alternative to CPAP. It is a custom-made type of appliance that moves your lower jaw forward and opens your bite.

This in turn will hold your tongue forward and your throat muscles are then activated to open the airway, so your airway stays open and won’t relax and collapse when you’re asleep. It is is an effective, non-invasive and comfortable solution.
