Cone beam computed tomography (CBCT) imaging has had a tremendous impact on the practice of orthodontics and craniofacial surgery since its inception almost a decade ago. However, the limitations and pitfalls regarding this imaging method should be addressed in order to fully appreciate and correctly apply the possibilities that CBCT imaging offers. The aim of this thesis was to address the issues regarding limitations of CBCT as an imaging modality in orthodontics.

In all aspects of CBCT imaging inherent limitations and pitfalls exist. The technical advances regarding further radiation reduction and improved image quality of CBCT imaging is rapidly evolving. Therefore, CBCT imaging will play an even more important role in orthodontics and maxillofacial surgery in the near future. It is expected that future application of CBCT images will take full advantage of the potential of the 3D images, especially in cephalometry and planning of maxillofacial surgery. In addition, future clinical studies will use 3D superimposition which might cast a brighter light on the prediction of treatment outcomes. New applications, not possible with traditional radiography e.g., the use of mirror imaging, will be continually developed and evaluated to determine if the benefits of the CBCT images outweigh the risks. Finally, the use of CBCT imaging brings added ethical and legal responsibilities for the clinician which should not be taken lightly.
