What is cervical anchorage (headgear) designed to do?

Exert mesial forces on mandibular teeth
Move maxillary teeth forward
Exert distal forces on maxillary teeth
Stabilize the lower jaw

The correct answer is: Exert distal forces on maxillary teeth

Cervical anchorage, commonly referred to as headgear, is designed to exert distal forces on maxillary teeth. This orthodontic device is primarily used to control the position of the upper molars and to help correct dental arch relationships. By applying gentle and consistent distal forces, headgear helps to move the maxillary molars backward in relation to the mandibular teeth, which can be particularly useful in cases of Class II malocclusion where the upper teeth are positioned too far forward. This functionality allows for adjustments in the overall alignment of the teeth and contributes to the proper occlusion of the bite as treatment progresses. The use of headgear is often essential in developing an ideal dental arch that can promote a more harmonious relationship between the upper and lower teeth. In contrast, the other options do not accurately reflect the role of headgear in orthodontic treatment.
