Cephalometric Analysis: History And Clinical Application, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

When roentgen cephalometry was first introduced to the orthodontic profession in 1931 by Broadbent in the USA and Hofrath in Germany it was a major milestone in terms of new diagnostic tools available to orthodontists. Until that time only clinical observation and study casts of the patients had been available to the clinician but now a more in depth understanding of the facial makeup became possible. This meant that each patient’s malocclusion could now be related to their facial skeletal and dental morphology. The dentoalveolar components could now be studied in detail and better treatment plans could be developed that …
