What does a head frame do?
A head frame, also known as a headgear, is an orthodontic appliance that is used to correct the alignment of the upper teeth and jaw. It consists of a metal framework that is attached to the molars with bands or brackets, and extends around the back of the head.
The main function of a head frame is to apply gentle, continuous force on the upper jaw and teeth, directing their growth and movement. It is commonly used in cases where there is an overbite, crossbite, or excessive protrusion of the upper jaw.
To understand how a head frame works, it is helpful to know a little bit about orthodontic principles. The human jaw consists of two bones, the upper (maxilla) and the lower (mandible). In normal occlusion, or bite, the upper teeth should slightly overlap the lower teeth. However, in some cases, the alignment of the upper jaw and teeth is not optimal. This can lead to functional and aesthetic problems.
The head frame is designed to modify the growth of the upper jaw and teeth by exerting forces on them. By applying a specific amount of force in a particular direction, the head frame helps to guide the jaw and teeth into their proper positions over time. This can help to correct the bite, improve facial symmetry, and create a harmonious dental occlusion.
It is important to note that a head frame is usually used as part of a comprehensive orthodontic treatment plan, and it is often combined with other appliances such as braces or aligners. The specific design and use of the head frame will depend on the individual needs of each patient, as determined by an orthodontist.
