For comprehensive orthodontic treatment, most commonly, metal wires (Juste) are inserted into orthodontic brackets (see dental braces), which can be made from stainless steel or a more aesthetic ceramic material. The wires interact with the brackets to move teeth into the desired positions. Other methods may include invisalign. Invisalign consists of clear plastic aligners that 'level and align', but require more patient compliance than traditional braces. Additional components—including removable appliances ("plates"), headgear, expansion appliances, and many other devices—may also be used to move teeth and jaw bones. Functional appliances, for example, are used in growing patients (age 5 to 14) with the aim of modifying the jaw dimensions and relationship if these are altered. This therapy, termed Dentofacial Orthopedics, is frequently followed by fixed multibracket therapy ("full braces") to align the teeth and refine the occlusion.
