Cone-beam computed tomography is the imaging technique of choice for comprehensive orthodontic assessment

Abstract

It is interesting to observe the adoption of new technology in dentistry and orthodontics. Of particular interest is the use of cone-beam computed tomography (CBCT) as the imaging protocol of choice for comprehensive orthodontic treatment. A concise review of the diffusion of innovation in dentistry was published by Parashos and Messer, who concluded that the adoption of technology is affected by factors that “include a complex interplay of perceived benefits and advantages, and psychosocial and behavioral factors, in decision-making.” Lateral and posteroanterior cephalograms were introduced to orthodontics in the early 1930s by Broadbent; yet, adoption of this technology, which is an accepted standard today, was still being resisted when Steiner wrote in 1953 about the use of cephalogram films: “It has been claimed by many that it is a tool of the research laboratory and that the difficulties and expense of its use in clinical practice are not justified. Many have argued that the information gained from cephalometric films, when used with present methods of assessment, do not contribute sufficient information to change, or influence, their plans of treatment.” Steiner’s statement could easily be applied to the use of CBCT today. A recent review suggested that CBCT should be used as an adjunct imaging technique in orthodontics. I propose that, although we still have much to learn about how to best use CBCT imaging to improve the outcomes of orthodontic treatment, we know enough about its application to consider it the imaging of choice for comprehensive orthodontic treatment.
