Self-Ligation in Orthodontics

THE EDITORS Both editors graduated from the School of Dentistry, University of Athens (Greece) and the Orthodontic postgraduate program of the Ohio State University, earning a Master's degree. Theodore Eliades additionally holds a doctorate in biomedical materials from the University of Athens, and a PhD in biomaterials from the University of Manchester. He is an Associate Professor of Orthodontics at the Aristotle University of Thessaloniki (Greece), and affiliated with institutes in the USA and EU (Texas, Marquette, Manchester, and Bonn). His research on biomaterials has generated 85 articles, 15 chapters and 4 books, the diffusion of which into fields associated with natural and engineering sciences led to a fellowship at the Institute of Materials, Minerals and Mining, and a membership in both the Royal Society of Chemistry and the Institute of Physics. Dr Eliades is Editor-in-Chief of the forthcoming Journal of Dental Biomechanics (Sage), Associate Editor of the European Journal of Orthodontics, and the American Journal of Orthodontics and Dentofacial Orthopedics, Editorial Board member in 5, and reviewer in 20 journals.Nikolaos Pandis completed a fellowship in Craniofacial Orthodontics at the University of Texas, Southwester Medical Center. He is currently a doctoral Fellow at the University of Bonn and enrolled in the Master of Clinical Trials program at the College of Hygiene and Tropical Medicine, University of London. He has published over 20 articles in the areas of self-ligating appliances and bonding, and is a Diplomate of the American Board of Orthodontics. Dr Pandis maintains an orthodontic practice in Corfu, Greece.

"The introduction and subsequent 12 chapters have been written by a pool of 18 internation authors.  Each chapter is supported by literature references and there is a four-page index." (BDA News, December 2010)
