Final answer:
A headgear placed on the cervical or pull up areas is often used to correct Class II malocclusions, which typically present as overbite problems. The malocclusion is not related to conditions such as craniosynostosis where the skull shape is abnormal but the brain is able to continue growing normally. The headgear applies precise pressure to reposition the jaw and correct the teeth misalignment.
Step-by-step explanation:
When a headgear is placed on the cervical or pull up areas, it is commonly used to correct Class II malocclusions.
In context of the information given about early fusion of a suture in primary craniosynostosis, it's important to understand that this condition could cause a misshapen skull. However, despite this abnormality, the brain continues to grow, and there is no abnormal neurological development.
Generally, Class II malocclusions often result in overbite problems where the upper jaw and teeth significantly overlap the lower ones. The headgear can apply a specific pressure to correct this misalignment.
