Cervical Headgear

This is applied via an elastic strap or spring, which runs around the neck (Fig. 8 a). It has the advantage of being relatively unobtrusive and easy to fit. However, it does tend to extrude the upper molars and tip them distally because of the downward and backward direction of force. This later effect can be counteracted to some degree by adjusting the height and length of the outer bow. Cervical headgear should not be attached to removable appliances because it is prone to dislodge the appliance and propel it to the back of the mouth.
