Cephalometry is a very useful technique in dentistry and especially in orthodontics, since it allows obtaining measurements of the skull from radiographs that are then traced on an acetate to establish the most significant anatomical points and to measure the distances and relationships between each other and others (bones, muscles, teeth, etc.) according to different criteria and then comparing them with normal patterns.
It is for this reason that cephalometry is a fundamental diagnostic procedure before starting any orthodontic treatment, since it allows determining the morphological, placement and growth abnormalities of the teeth, in order to establish the objective of the treatment and be able to adequately monitor the same.
During the test, the patient has to stand or sit. The most important thing is that the head is well positioned. It is normally done in a lateral plane, although you may be asked for a frontal plane.
