What does cephalometry involve?

Measuring dental occlusion
Taking measurements of the skull
Analyzing bite patterns
Examining jaw alignment

The correct answer is: Taking measurements of the skull

Cephalometry involves taking measurements of the skull, particularly the head's dimensions and relationships between various craniofacial structures. This practice is essential in orthodontics as it allows practitioners to assess the growth patterns and relationships of the teeth and jaws in a three-dimensional space. By obtaining precise measurements through radiographic images (like cephalometric X-rays), orthodontists can create treatment plans that are tailored to the individual needs of their patients. These measurements help in understanding the anatomical relationships and in planning for orthodontic interventions effectively. The other options, while related to orthodontic practices, do not specifically describe cephalometry. Measuring dental occlusion refers to how the upper and lower teeth meet, analyzing bite patterns focuses on the functional relationship between the teeth, and examining jaw alignment addresses how the jaws fit together. Each of these plays a role in orthodontic diagnosis and treatment planning but does not encompass the specific focus of cephalometry itself.
