2018 Annual Session Conference

Will 3D Photogrammetry replace Cephalometrics in the 21st Century?

Description

As we enter an age of radiation hygiene restricting routine radiographic exposures that do not have a direct diagnostic benefit to the patient, many countries have already made it illegal to take final cephalometric radiographs at the end of the orthodontic treatment. Advances in 3D dentofacial photogrammetry is now a viable alternative for orthodontists to diagnose dentofacial discrepancies and quantify changes due to growth and/or treatment. Studies confirm that the eyes can be used as an alternative to the cranial base. This allows the practitioner to limit the radiographic exposure to the teeth and the surrounding structures eliminating the need to expose the upper half of the face to ionizing radiation. This lecture covers evidence that supports using 3D dentofacial photogrammetry for orthodontic diagnosis as well as the equipment and software that would be needed to use it in every day orthodontic practice.

Learning Objectives:

  • Comprehend the ethical issues that relate to routine radiographic exposure of the cranial base.
  • Familiarize themselves with research related to using 3D photogrammetry for orthodontic diagnosis and the eyes as references instead of the cranial base.
  • Evaluate the set up that would be needed to use the method in their offices.
