The cervical headgears are modern form of headgears that are used more comfortably to check the extra growth of mandibular and maxillary bones in orthodontics. In this treatment the head gears are put on in such a fashion that it exerts pressure on the upper jaw and controls its growth.
Headgears have been in use since past 75 years typically for people who have overbites. The headgear holds back the growing of mandibular jaw and allows your lower jaw to balance with the upper one. Cervical headgear is required to wear by the patient approximately twelve-twenty two hours a day for effective results in balancing and managing the overbites. And you need to continue its wear for at least twelve to fifteen months or more. It all depends on the severity and the growth rate of the overbite along with the age of the patient.
The cervical headgear typically consists of three main parts:
The first one is called Face bow. Its fixed to the rear upper as well as lower molar. here can also be low and upper face bows too, to wear independently.
The second component is called the head cap. It has straps to fit around the head. Its then attached with the face bow with the help of strings or elastic band. Sometimes for comfort and safety additional straps may also be fitted.
The third one is called Attachment, which is actually the set of those springs and bands used to fix the head cap and the face bow. The orthodontic surgeon will help you learn the tactics of wearing them. For one or two days you may find it difficult but once you get used to it, you can very easily wear it in a minute or less time. Thus, cervical headgear can give you the perfect smile you want.
