What effect does a lower jaw advancement device have on sleep apnea?

A lower jaw advancement device primarily works by repositioning the jaw forward during sleep. This forward position helps to open the airway, thereby decreasing airway resistance. In patients with obstructive sleep apnea (OSA), airway blockage can occur due to the relaxation of the throat muscles and tissues, leading to disruptions in breathing. By advancing the lower jaw, the device creates a more open space in the airway, allowing for smoother airflow and reducing the likelihood of obstructions during sleep.

While options such as increasing airway pressure or ensuring regular breathing patterns may seem beneficial, they are not the direct effects of a lower jaw advancement device. Additionally, while the device may help mitigate snoring, which is often associated with obstructed airways, its primary function is to decrease resistance in the airway rather than solely focusing on snoring prevention.
