What is a method for evaluating the anatomic basis for malocclusion?

A cephalometric radiograph is a specialized type of X-ray used in orthodontics to evaluate the relationships among the teeth, jaw, and skull. It provides a lateral view of the skull and allows for precise measurements of various anatomic structures. This information is crucial when diagnosing malocclusion, as it helps in understanding the underlying skeletal relationships and growth patterns of the jaws. By analyzing these measurements, orthodontists can determine the type and extent of malocclusion and devise an appropriate treatment plan.

While panoramic radiographs provide a broader view of the dentition and surrounding structures, they lack the detailed geometric measurements necessary for assessing the spatial relationships that contribute to malocclusion. Intraoral exams focus more on the teeth and soft tissues, and clinical photographs capture the condition of the teeth and smile, but neither provide the systematic anatomical measurement required for evaluating skeletal relationships in depth. Thus, the cephalometric radiograph stands out as the most effective method for this purpose.
