Which type of radiograph is most commonly used for orthodontic patients?

The cephalometric radiograph is the most commonly used type of radiograph for orthodontic patients because it provides a lateral view of the skull and facial structures. This type of radiograph is essential in orthodontics as it helps in the evaluation of a patient's skeletal and dental relationships, allowing for proper diagnosis and treatment planning. It provides key information such as the size and position of the jaws, the relationship between the upper and lower teeth, and the overall facial symmetry.

By analyzing these aspects, orthodontists can determine treatment options and predict changes in tooth position and jaw development over time, which is crucial for effective orthodontic treatment. The ability to assess both hard and soft tissue structures through cephalometric analysis makes it an invaluable tool in the orthodontic field.
