353:, which the orthodontist will adjust so it is correctly positioned in front of the patient's mouth to get the elastics to apply the force in the desired direction. The mouth yoke has a number of hooks (four to six depending on type of appliance, see photo with six hooks), which allows the orthodontist to attach elastics or springs directly into from the facemask into the patient's mouth. The frame allows the patient to move his or her head freely and to talk. All other oral activities are typically limited or restricted, such as eating or playing sports or playing a wind musical instruments, although drinking is recommended using a straw so as not to remove the whole appliance at night or in the day when thirsty.

Multiple appliances and accessories are typically used along with the headgear, such as: power chains, coil springs, twin blocks, plates or retainers, facemasks, a headgear helmet (a headgear helmet is a

359:: some facemasks and all reverse-pull headgear have a second part which consists of a head cap, and is made up of a number of straps fitting around the patient's head. In this case the head cap is used to stabilize the face-frame described above and to ensure it is held correctly in position (see photo example of reverse-pull headgear with head-strap/cap).
316:
The appliance normally consists of a frame or a center bars that are strapped to the patient's head during a fitting appointment. The frame has a section which is positioned in front of the patient's mouth, which allows for the attachment of elastic or rubber bands directly into the mouth area. These

Researchers who have studied the long-term effects of orthodontic headgear have found that it may flatten the face and prevent the chin from coming forward, pushing both the upper and lower jaw down and back, into the airway. In more technical terms, it inhibits the natural growth of the jaws and

The need for headgear in orthodontics and its application by practitioners has somewhat decreased in recent years as some orthodontists use temporary implants (i.e., temporary anchorage devices) inside the patient's mouth to perform the same tooth movements. However, the headgear is still widely

The appliance is very effective in correcting Class III orthodontic problems in younger or adolescent patients that are still growing. Initially, it can be difficult for children to wear a mask or headgear, however most doctors and parents agree that children and adolescence adapt quickly to such

Facebow: first, the facebow (or J-Hooks) is fitted with a metal arch onto headgear tubes attached to the rear upper and lower molars. This facebow then extends out of the mouth and around the patients face. J-Hooks are different in that they hook into the patients mouth and attach directly to the

Unlike braces, headgear is worn partially outside of the mouth. An orthodontist may recommend headgear for a patient if their bite is more severely out of alignment. The device typically transfers the force to the teeth via a facebow or J hooks to the patient's

In some cases surgery is required in conjunction with a facemask or reverse-pull headgear. Many parents and doctors recommend using early intervention (typically between ages 7 to 13) by using a facemask to avoid costly and painful surgical procedures later.

Headgear is most commonly used to correct the bite of the patient. The headgear attaches to the braces via metal hooks or a facebow. Straps or a head cap anchor the headgear to the back of the head or neck. In some situations, both are used.

Parents should be aware that their child is often better-off wearing a facemask or headgear to avoid later surgery and the patient, friends and school peers normally get used to the new appliance after just a few weeks of wear.
