"This is a great textbook, and I will use it in my classes. Highly organized and elaborately illustrated, the authors' work is inspired by problem-based learning and stimulates cognitive processes by encouraging critical thinking. Their text deserves a 'must read' category for orthodontic professionals of all ages."

Dr. Jeryl D. English DDS, MS, Chairman and Graduate Program Director, Department of Orthodontics, The University of Texas Health Science Center at Houston

"A terrific book for students of orthodontics and dentofacial orthopedics, covering the vertical dimension and much more. A wide range of cases are presented, treatment plans are realistic, and the authors openly discuss complications encountered during treatment."

Dr. Greg J. Huang, DMD, MSD, MPH Professor and Chair Department of Orthodontics, The University of Washington School of Dentistry

"This comprehensive text prepares the reader in the context of a mini-residency with a question answer teaching style. Resident and experienced orthodontists can match their cases with fully worked up patients and alternative treatment options. Well written."

Dr. Katherine L. Vig, BDS, MS, FDS, D.Orth Professor Emeritus and Former Head of Orthodontics, The Ohio State University College of Dentistry
