Cone-beam computerized tomography and the transverse dimension

Abstract

For decades, orthodontists have largely been limited to 2D analyses for investigating the effects of palatal expansion. The advent of CBCT has added the third dimension, and the ability to investigate the mechanisms of palatal expansion and different expansion techniques has never been more promising. However, CBCT is not without risk and cost, and debate exists on the role CBCT should play in everyday orthodontic practice, as well as in orthodontic research. We asked Dr. Flores-Mir to respond to a list of specific questions regarding the impact this new technology has had on our knowledge of the transverse dimension.
