Orthodontic high pull headgear is fitted in two steps, as there are two pieces of equipment included with your child's headgear. First, the portion that goes into the mouth (and also extends outside the cheeks from an attachment at the corners of the lips). This portion is called the face bow or just bow. It has an inner and an outer portion. The inner portion of the face bow attaches to the teeth via bands attached to the back teeth.
The second part of the high pull headgear is the head strap. The head strap attaches to the outer bow of the face bow and applies force from the top and back of the head for stability or anchorage. Elastic straps built into the head strap allow your child's orthodontist to adjust the tension or strength of the headgear. During treatment this elastic strap might be adjusted or the tension increased in order to continue progress with jaw alignment treatment.
