About the Authors
Charles J. Burstone, DDS, MS (1928 – 2015), was a pioneer in his field, introducing biomechanical concepts to clinical orthodontics by formulating the segmented arch technique. He was responsible of developing robust orthodontics departments at Indiana University and later at the University of Connecticut, which both became internationally known for their research and for the quality of their graduates, many of whom went on to become outstanding clinicians and teachers throughout the world. Always an innovator, Dr Burstone was an early developer of interactive computer programs for diagnosis and treatment planning, a codeveloper of new wires using titanium-molybdenum alloy (TMA) and Chinese nickel titanium (NiTi) alloy, and the lead researcher in the development of long-fiber-reinforced composites in appliance design. He held various patents related to his work. As an active member of numerous dental societies and organizations, Dr Burstone was the recipient of many distinguished awards and honors. He published many books and chapters as well more than 200 articles in refereed journals. Dr Burstone was professor emeritus of the Division of Orthodontics at the University of Connecticut, where he donated much of his time and energy until his passing in February 2015.
Kwangchul Choy, DDS, MS, PhD, is a former professor of orthodontics at Yonsei University. He completed his orthodontic training at Yonsei University and was a research fellow and visiting professor at the University of Connecticut. Dr Choy is currently a clinical professor at Yonsei University as well as an adjunct professor of orthodontics at Ewha Womans University. He has published over 30 papers and book chapters in the field of biomechanics of tooth movement and orthodontic appliances. Dr Choy lectures around the world on biomechanics and maintains a private practice in Seoul, South Korea.
