Head gear should not be prescribed in which of the following situation
**Core Concept**
Head gear is a type of orthodontic appliance used to treat mandibular prognathism or Class III malocclusion. It is a removable appliance that applies a downward and backward force on the maxilla to correct the mandibular excess. The use of head gear is based on the principle of altering the growth pattern of the maxilla and mandible.
**Why the Correct Answer is Right**
Head gear should not be prescribed in cases of craniosynostosis, a congenital condition where one or more of the sutures in the skull fuse prematurely. This is because craniosynostosis can lead to increased intracranial pressure and head gear may exacerbate this condition. In such cases, a more conservative approach or surgical intervention may be necessary to address the underlying condition.
