What type of malocclusion is corrected by placing headgear in the cervical or pull-up areas?

Malocclusion I
Malocclusion II
Malocclusion III
Malocclusion IV

The correct answer is: Malocclusion II

The placement of headgear in the cervical or pull-up areas is specifically designed to correct Malocclusion II, often characterized by the discrepancy in the positioning of the molars where the upper molars are positioned too far forward in relation to the lower molars. This type of malocclusion frequently presents as a class II division, where the patient's bite is significantly affected, leading to increased overjet and the potential for the teeth to be angled or misaligned. Cervical pull headgear applies a gentle force that encourages the upper molars to move backward and allows for the proper alignment of the dental arches, thus creating an ideal occlusion. The mechanics of this type of headgear work effectively to adjust the position of the maxillary molars, facilitating improved bite relations and contributing to long-term orthodontic success. Other types of malocclusion, such as I, III, and IV, do not typically require this specific application of headgear, making Malocclusion II the appropriate context for this treatment strategy.
