Face Pulling : A Mechanical Engineering Challenge

The theory behind a facepulling headgear is rather simple. You want to apply constant forces on the palate to move it forward, upward and to expand it. Creating a headgear that is light enough to be worn for hours and that is comfortable enough to sleep with is the challenge.

Headgear_Force_Forward

First, there is the forward force. The biggest surface to apply this force is the anterior region of the palate, from where it will drag the maxilla forward. A forward force alone is problematic, because it would rotate the maxilla in a counter-clockwise direction and disrupt a healthy bite.
