Cervical Headgear (cHG)

Cervical headgear is used to help retract or retard the forward growth of the upper jaw and teeth. This type of appliance is referred to as an extra oral appliance because it has a strap that is worn around the neck (cervical area) and is then attached to the braces within the mouth. The headgear applies a constant pressure on the upper teeth and maxilla to help prevent further growth and forward movement of the upper teeth, and to retract the upper molars. This appliance is typically used to help correct a large overjet (commonly referred to as the “overbite”) of the upper teeth.
