Are We Practicing Evidence Based Orthodontics: Biomechanics, Aligners and TADs

Ravindra Nanda

Dr. Ravindra Nanda is Professor Emeritus, Former UConn Alumni Endowed Chair and Head of the Department of Craniofacial Sciences and Division of Orthodontics, University of Connecticut, Farmington, Connecticut, U.S.A. He is also an Adjunct Professor at The Forsyth Institute, Cambridge, Ma, USA.

He received his dental and orthodontic training first at Lucknow, India and then from Nymegen, The Netherlands and the University of Connecticut. He also received a Ph.D. from the University of Nymegen. Since 1972 he has been associated with the University of Connecticut in various academic roles including Chair of Orthodontics from 1991 to 2017.

Dr. Nanda has been active in orthodontic research in the area of biomechanics, clinical trials and acceleration of orthodontic treatment. He has authored with his colleagues more than 250 scientific papers. He is Editor-in-Chief of Progress in Orthodontics and he is on the editorial board of ten different national and international orthodontic journals. He is also an associate editor of Journal of Clinical Orthodontics.

He is an active member of various organizations, including the American Association of Orthodontists, European Orthodontic Society and Edward H. Angle Society. Dr. Nanda is a Diplomate of the American Board of Orthodontics. He has given numerous named lectures at national and international societies including Mershon and Angle Heritage Lectures at the American Association of Orthodontics and Sheldon Friel Lecture at the 2011 EOS Congress. He has been recognized with Honorary memberships and has received various awards from numerous international orthodontic organizations.

Dr.Nanda has authored and co-authored eight text books Retention and Stability (with Dr. Burstone), Biomechanics in Clinical Orthodontics , Biomechanic and Esthetic Strategies In Clinical Orthodontics, Temporary Anchorage Devices in Orthodontics (with Dr. Uribe), Current Therapy in Orthodontics(with Dr. Kapila), Esthetics and Biomechanics in Orthodontics, and recently ЁА Orthodontics, two volumes ЁА (with Prof. Farronato), and Atlas of Complex Orthodontics (with Dr. Uribe). He has two new books coming out in 2019, Temporary Anchorage Devices (with Drs. Uribe and Yadav) and Principles and Biomechanics of Aligner Orthodontic Treatment (with Castroflorio, Garino and Ojima).

Lecture Description

Orthodontics specialty is quite unique and different than medicine as far as introduction of new devices is concerned as well as existing treatment modalities. There is a serious lack of randomized trials and prospective studies as noted by various systematic reviews and meta-analyses. Almost always new devices are being marketed by the orthodontic companies without any background evidence- based research or peer reviewed publications. This presentation will concentrate on how aligners and temporary anchorage devices (TADs) were introduced and adopted by the orthodontic profession without any supportive data about their efficacy for treating various malocclusions Most of the understanding of biomechanics and research related to TADs has been exemplary few years after their introduction. Unfortunately, it is not the same with aligners. Research studies on aligners lagged considerably during the first 15 years or so following their introduction. Only in recent years research has shown limited efficacy of various tooth movements with conventional aligners, pointing out limitations due to inadequate biomechanics, not so optimal attachments, rigid material, and compliance issues. This presentation will go over recent research and advances in mechanics and aligner materials.
