Orthodontic imaging is a routine procedure in offices, yet fundamental questions regarding its purpose, information provided and reliability are generally not well-understood. This presentation reviews the challenges of common orthodontic images and critically evaluates their reliability from an evidence-based perspective. Attendees may be surprised to learn about the scientific conclusions regarding common orthodontic images. For these reasons, there is rapid change towards improved imaging using the latest technology known as Cone-Beam CT (CBCT). This technology gives clinicians a choice toward improved clarity of images and more reliable clinical information. Considerations such as patient perception of 3D imaging and select cases will be presented to reinforce the limitations of conventional imaging and the advantages of multi-dimensional imaging.

Learning Objectives:

  • Learn the limitations of conventional orthodontic imaging (superimposition, distortion, magnification, and lack of alternative perspectives)
  • Learn the fundamentals of 3D imaging using Cone beam CT
  • Learn the common orthodontic applications of 3D imaging (cephalometrics, impacted teeth, TMJ evaluation, airway assessment, review of the dentition, rule out pathology, etc.)
