How do I trace cephalometric?
Manual tracing of cephalometric Alms is performed by identifying radio-graphic landmarks on acetate overlays and using these reference points to construct lines, planes and angles to enable the measurement of linear and angular values, using a millimetre scale and a protractor.
What would an orthodontist use a cephalometric tracing for?
Cephalometrics can help orthodontists determine whether malocclusions are due to skeletal or alveolar deviations, and in patients with skeletal discrepancy, cephalometrics can identify if this is due to dento-alveolar compensation or dysplastic development.

What is SNA SNB ANB?
The ANB angle measures the relative position of the maxilla to mandible. The ANB angle can be measured or calculated from the formula: ANB = SNA – SNB. A positive ANB angle indicates that the maxilla is positioned anteriorly relatively to the mandible (Class I or Class II malocclusion cases).
What is cephalometric radiograph?
Cephalometric x-rays (also called ceph x-rays or radiographs) show a side view of your head, exposing teeth, jaw, and surrounding structures. This technology is considered safe and often useful or necessary to help professionals evaluate and assist patients.
